On February 5, 2022, Degirmencioglu, Ismail; Iren, Kubra; Yalcin, Izzet; Gol, Cem; Durmus, Mahmut published an article.Name: 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone The title of the article was Synthesis of axially disubstituted silicon(IV) phthalocyanines and investigation of their photophysical and photochemical properties. And the article contained the following:
In this study, the axially 1-(4-(3-(6-hydroxyhexyl)-3,4-dihydro-2H-benzo[e][1,3]oxazin-6-yl)piperazin-1-yl)ethanone and 1-(4-(3-(2-(2-hydroxyethoxy)ethyl)-3,4-dihydro-2H-benzo[e][1,3]oxazin-6-yl)piperazin-1-yl)ethanone disubstituted silicon(IV) phthalocyanines and their corresponding quaternized derivatives were synthesized for the first time as candidate photosensitizers for photodynamic therapy (PDT) in cancer treatment. The structures of these novel compounds were confirmed by some spectroscopic techniques such as FT-IR, 1H NMR, 13C NMR, UV-Vis, and mass. The axially substitution increased the solubility of the silicon(IV) phthalocyanines. The prepared silicon(IV) phthalocyanines showed great results achieved from photochem. and photophys. investigations in DMSO solution Especially, high singlet oxygen and the fluorescence quantum yield values of the quaternized silicon (IV) phthalocyanines indicates that these compounds have major potential as photosensitizers in PDT. Furthermore, studied silicon(IV) phthalocyanine complexes could be classified as the stable photosensitizer in accordance with photodegradation study results. The fluorescence quenching behavior of these phthalocyanine complexes was also examined using fluorescence quenching method by 1,4-benzoquinone (BQ). The experimental process involved the reaction of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone(cas: 67914-60-7).Name: 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone
