Заглавие : Polyaromatic hydrocarbon (PAH)-based aza-POPOPS: synthesis, photophysical studies, and nitroanalyte sensing abilities Место публикации : International journal of molecular sciences. - 2023. - Vol. 24, № 12. - С. 10084 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): aza-popops--click reactions--chemosensors Аннотация: 1,4-Bis(5-phenyl-2-oxazolyl)benzene (POPOP) is a common scintillation fluorescent laser dye. In this manuscript, the synthesis of 2-Ar-5-(4-(4-Ar'-1H-1,2,3-triazol-1-yl)phenyl)-1,3,4-oxadiazoles (Ar, Ar' = Ph, naphtalenyl-2, pyrenyl-1, triphenilenyl-2), as PAH-based aza-analogues of POPOP, by means of Cu-catalyzed click reaction between 2-(4-azidophenyl)-5-Ar-1,3,4-oxadiazole and terminal ethynyl-substituted PAHs is reported. An investigation of the photophysical properties of the obtained products was carried out, and their sensory response to nitroanalytes was evaluated. In the case of pyrenyl-1-substituted aza-POPOP, dramatic fluorescence quenching by nitroanalytes was observed. Доп.точки доступа: Mohammed, M. S. I.; Kovalev, I. S.; Slovesnova, N. V.; Sadieva, L.
