Chemosensor Benzoylhydrazones of Coumarin Aldehides

Abstract: Аннотация. Синтезированы бензоилгидразоны 6,7-дигидрокси-4-метил-8-формилкумарина и 3,4-бензо-7-гидрокси-8-формилкумарина, проявляющие свойства хромогенных и флуоресцентных хемосенсоров на катионы ряда d-металлов, а также фторид-, цианид-и ацетат-анионы. Их строение установлено при помощи методов электронной, колебательной и ЯМР 1 Н-спектроскопии, а также масс-спектрометрии. ИК-спектры содержат полосы поглощения, характерные для валентных коле-баний карбонильных групп α-пиронового кольца кумаринового фрагмента… Show more

“…The detection limit is < 3 μM cyanide (dissolved in a acetonitrile medium): the coumarin group generates a bright blue fluorescent signal. The substances 6,7-dihydroxy-4-methyl-8-formylcoumarin and 3,4-benzo-7-hydroxy-8-formylcoumarin can also be used as chromogenic and fluorescent chemosensors to detect cyanide anions and Cu 2+ cations [ 74 ]. DTMC (7-(4,6-dichloro-1,3,5-triazinyl-2-amino)-4-methylcoumarin) was proposed for the chemiluminescent determination of hydrogen peroxide by the chemiluminescent method [ 75 ].…”
