Quality Control of 1,10-Phenanthroline. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1,10-Phenanthroline, is researched, Molecular C12H8N2, CAS is 66-71-7, about Smartphone-based colorimetric method for determining sulfites in wine using a universal clamp sample holder and microfluidic cotton swab-based analytical device. Author is Khamkhajorn, Chutikarn; Pencharee, Somkid; Jakmunee, Jaroon; Youngvises, Napaporn.

A universal clamp sample holder was newly designed and fabricated for use with a microfluidic cotton swab-based anal. device (μCSAD) in smartphone-based colorimetric determination of sulfites in wine. In the process, sulfite (SO2-3) was converted to volatile SO2 by acidification, the SO2 reduced Fe(III) to Fe(II) which finally formed the complex of Fe(II)-phenanthroline with a red color. The latter two reactions occurred on a cotton swab head hanging over the sample solution in a vial. Then, the swab was placed in the sample holder that also contained a lens and a light-emitting diode, to be photographed by the built-in camera of the smartphone. A mobile software application was designed to generate the calibration equation and evaluate the amount of sulfites in the sample. The linear ranges were 0.30-2.25 as SO2 (R2 = 0.9931) and 2.25-18.75 mg L-1 as SO2 (R2 = 0.9956). The limit of detection was 100μg L-1. Compared to the Ripper method, the developed method showed no significant differences in measuring the sulfites in wine samples. This μCSAD is simple, cost-effectiveness, and eco-friendly. Moreover, the designed universal clamp holder and the software application can be used with multiple brands and models of smartphones.

Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1,10-Phenanthroline, is researched, Molecular C12H8N2, CAS is 66-71-7, about Achieving host-free near-ultraviolet electroluminescence via electronic state engineering with phosphine oxide. Author is Chen, Shuo; Zhang, Chunying; Xu, Hui.

Developing near-UV (NUV) emitters with board band gap and high photoluminescence quantum efficiency (PLQY) is a formidable challenge for organic light-emitting diode (OLED) applications. Herein, two NUV emitters PhImPOCz and PhImPOtBuCz were designed on the basis of phosphine oxide (PO) modification. It is showed that based on crescent phenanthrene (Phen) fused with acceptor imidazole (Im) as NUV chromophore, carbazole (Cz) or 3,6-di-tertbutyl carbazole (tBuCz) donors make the mol. bipolar character to balance carrier recombination in emissive layer (EML). More significantly, besides steric hindrance for aggregation suppression, the introduction of triphenylphosphine enhances localized excited feature of the electronic states, and prevents the red shift induced by intra- and inter- mol. charge transfer, which establishes the basis for fabricating host-free NUV OLEDs. The non-doped devices based on the PhImPOCz and PhImPOtBuCz emitters achieved the low turn-on voltages of 4.2 V and 4.4 V, and the state-of-the-art external quantum efficiency (EQE) up to 2.81% and 3.42%, resp. This work demonstrates the significance of electronic state engineering for high-energy OLED applications.

The emergence of drug-resistant pathogens has greatly limited the use of antibiotics in treating microbial infections. Therefore, Cu complexes have emerged as potential alternatives to ordinary antibiotics. Ternary Cu(II) complexes with N-benzoyl-DL-phenylalanine (Bzphe) and imidazole (Imi), methylimidazole (Mimi), 2,2′-bipyridine (Bipy), and 1,10-phenanthroline (Phen) ligands were prepared and investigated for antimicrobial efficacy against two Gram-pos. bacteria (Bacillus subtilis and Micrococcus luteus), one Gram-neg. bacteria (Escherichia coli), and three fungal cultures (Aspergillus niger, Candida glabrata, and Saccharomyces cerevisiae). The new complexes were characterized by elemental anal., IR spectroscopy, electronic spectroscopy, thermogravimetry, and measurements of their molar conductivity and m.p. The formulas of the new complexes were Cu(Bzphe)2(Imi)2(OH2)2, [Cu(Bzphe)2(Mimi)2(OH2)2], Cu(Bzphe)2(Bipy)(OH2)2, and Cu(Bzphe)2(Phen)(OH2)2. The obtained data revealed that the Bzphe invariably coordinates to the Cu(II) ions through carboxylic oxygen as a monobasic ligand. The addition of secondary ligands such as amines does not affect the unidentate coordination behavior of the Bzphe. The new compounds were screened for antimicrobial activity against different strains of bacteria and fungi. The results for the Bzphe ligand and its mixed-ligand Cu(II) complexes showed that the ligands exhibit low potency to inhibit the growth of both Gram-pos. bacteria (B. subtilis and M. luteus) and Gram-neg. bacteria (E. coli). However, the new ternary complexes greatly suppressed the growth of these pathogens according to the order CuBipyBzphe > CuPhenBzphe > CuMimiBzphe > CuImiBzphe. In addition, computational studies using d. functional theory calculations and mol. docking experiments were carried out to characterize the mol. properties of the new complexes and provide insights into their role in inhibiting the growth of bacterial and fungal strains.

This literature about this compound(66-71-7)Quality Control of 1,10-Phenanthrolinehas given us a lot of inspiration, and I hope that the research on this compound(1,10-Phenanthroline) can be further advanced. Maybe we can get more compounds in a similar way.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1,10-Phenanthroline, is researched, Molecular C12H8N2, CAS is 66-71-7, about Phenanthroline bridging graphitic carbon nitride framework and Fe (II) ions to promote transfer of photogenerated electrons for selective photocatalytic reduction of Nitrophenols, the main research direction is phenanthroline graphitic carbon nitride nitrophenol photocatalytic reduction; Fe (II); Graphitic carbon nitride; Nitrophenols; Phenanthroline; Selective reduction.Formula: C12H8N2.

Nitrophenols (NPs) are widely used in industries and highly toxic to ecol. environment and human health. Because aminophenols (APs) are important chems., catalytic reduction of NPs via efficient and environment-friendly strategies is of great importance. Herein, we developed a green photocatalysis route to efficiently convert NPs to APs using a Fe (II) modified graphitic carbon nitride (g-C3N4) photocatalyst, where phenanthroline units were employed to bridge Fe (II) and carbon nitride framework. The optimized sample P-CN-8-Fe presented significantly improved absorption of visible light, separation of photogenerated charges and carrier transportation in comparison with the pristine g-C3N4 and the modified samples of CN-Fe and P-CN-8. Accordingly, the P-CN-8-Fe showed a high conversion (97%) of p-nitrophenol (p-NP) to p-aminophenol (p-AP) under 2 h visible light irradiation, and meanwhile possessed high photocatalytic durability. Its high activity was also demonstrated through photocatalytic reduction of other NPs and nitrobenzene compounds Finally, a possible mechanism was proposed for the photocatalytic reduction of p-NP by P-CN-8-Fe. This work provides an effective approach to prepare Fe (II) modified g-C3N4 through the bridging effect of phenanthroline group, which is a potential visible light driven photocatalyst for reduction of nitrobenzene derivatives

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 66-71-7, is researched, SMILESS is C1=CC3=C(C2=NC=CC=C12)N=CC=C3, Molecular C12H8N2Journal, Article, International Journal of Biological Macromolecules called Lignin-based fluorescence-switchable graphene quantum dots for Fe3+ and ascorbic acid detection, Author is Zhu, Lingyan; Li, Dongbing; Lu, Heng; Zhang, Shangkun; Gao, Hao, the main research direction is lignin fluorescence graphene quantum dot ascorbic acid detection; Alkali lignin; Fluorescence sensing; Graphene quantum dots.Quality Control of 1,10-Phenanthroline.

The synthesis of lignin-based graphene quantum dots (GQDs) with excellent fluorescence stability, quantum yield, and biocompatibility for sensitive and selective detection of Fe3+ and ascorbic acid (AA) has remained a challenging endeavor. Using an acidolysis process with 17.5% nitric acid followed by hydrothermal treatment at 200 °C, this study provided an improved synthesis route for the production of high-quality GQDs from alkali lignin. The nitrogen-doped GQDs exhibit remarkable fluorescence stability under a wide range of pH (3-10), duration (1-12 h), and [NaCl] (0-1000 mM) conditions, and have a high quantum yield of 28%. The GQDs or GQDs/Fe3+ sensing systems ([GQDs] at 50 mg L-1, [Fe3+] at 500 °mol L-1, and UV excitation at 370 nm) for fluorescence sensing of Fe3+ or AA have excellent sensitivity, selectivity, and reproducibility. For Fe3+ and AA, the limit of detection is 1.49 and 1.62 °mol L-1, resp. Mechanism investigation shows that photoluminescence quenching is caused by the formation of GQDs-Fe3+ complexes, whereas fluorescence recovery is due to Fe3+ reduction by AA.

Author is Vanco, Jan; Travnicek, Zdenek; Hosek, Jan; Dvorak, Zdenek.

Heteroleptic copper(II) complexes, containing prenylated flavonoid osajin isolated from the fruits of Maclura pomifera Schneid., were prepared and thoroughly characterized, including single crystal X-ray anal. Some of the following complexes of the general composition [Cu(L)(bpy)]NO3 (1), [Cu(L)(dimebpy)]NO3·2MeOH (2) [Cu(L)(phen)]NO3·H2O (3), [Cu(L)(bphen)]NO3 (4) and [Cu(L)(dppz)]NO3 (5), where HL stands for 3-(4-hydroxyphenyl)-5-hydroxy-8,8-dimethyl-6-(3-methylbut-2-ene-1-yl)-4H,8H-benzo[1,2-b:3,4-b′]dipyran-4-one (osajin), bpy = 2,2′-bipyridine, dimebpy = 4,4′-dimethyl-2,2′-bipyridine, phen = 1,10-phenanthroline, bphen = 4,7-diphenyl-1,10-phenanthroline and dppz = dipyrido[3,2-a:2′,3′-c]phenazine, were also monitored for their solution stability and interactions with cysteine and glutathione by mass spectrometry. The in vitro cytotoxicity of the complexes was evaluated against a panel of eight human cancer cell lines: (MCF-7, HOS, A549, PC-3, A2780, A2780R, Caco-2, and THP-1). The results revealed high antiproliferative activity of the complexes with the best IC50 values of 0.5-3.4 μM for complexes (4) and (5), containing the bulkier N,N′-donor ligands (bphen, and dppz, resp.). The complexes also revealed a relatively low toxicity towards human hepatocytes (IC50 values are higher than 100 μM in some cases), and thus proved to be highly selective towards the cancer cells. On the other hand, the complexes showed a strong in vitro nuclease effect using the model pUC-19 plasmid. In the model of lipopolysaccharide-stimulated (LPS) THP-1 monocytes, the complexes revealed ability to lower the activity of nuclear factor kappa-B/activator protein 1 (NF-κB /AP-1) system and decrease the secretion of tumor necrosis factor alpha (TNF-α). Thus, the complexes have been identified as strong antiproliferative and anti-inflammatory compounds

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1,10-Phenanthroline(SMILESS: C1=CC3=C(C2=NC=CC=C12)N=CC=C3,cas:66-71-7) is researched.HPLC of Formula: 54903-09-2. The article 《Synthesis and photophysical properties of metal complexes of curcumin dyes: Solvatochromism, acidochromism, and photoactivity》 in relation to this compound, is published in Dyes and Pigments. Let’s take a look at the latest research on this compound (cas:66-71-7).

Curcumin and its dyes have attracted attention due to their environment-sensitivity and optical properties. However, the free mol. has low photoactivity, which is a limitation for use in photodynamic therapy. To overcome this limitation, we proposed the chelation of a D-π-A-π-D curcumin dye (1) with the metals Cu (II) and Pd (II). The photophys. properties of the curcumin dyes were investigated in different solvents, using UV-vis spectroscopy and time-resolved/steady-state fluorescence techniques. In our results, all curcumin dyes exhibited a pos. solvatochromism from non-polar to polar solvents, with the Stokes’ shift in the range of 1895-4970 cm-1. The acidochromism studies were performed in chloroform solution and TLC plates using trifluoroacetic acid (TFA). The results exhibited a neg. acidochromism and fluorescence quenching upon gradual addition of TFA, demonstrating reversibility upon addition of triethylamine (TEA). The main mechanism which influences the solvatochromism/acidochromism is the ICT system and fluorescence lifetime decays exhibited mono-exponential fit for aprotic solvents and bi-exponential fit for protic solvents (EtOH and MeOH). Compared to the curcumin ligand (1), the metal complexes (1a-b) exhibited higher singlet oxygen quantum yields (ΦΔ = 0.36 and 0.54, resp.). The in vitro antimicrobial photoactivity of the compounds was evaluated against six different microorganisms. The results showed that the metal complexes (1a-b) exhibited both antileishmanial (MIC = 2.29μM against Leishmania amazonensis promastigotes) and antifungal (IC50 = 10μM against Sporothrix brasiliensis yeasts) activities, while the ligand showed no activity, suggesting the chelation with the metals Cu (II) and Pd (II) may improve its photoactivity.
