Синтез 4-(гет)арил- и 4,5-ди(гет)арил-замещенных пиримидинов и их использование в качестве сенсоров на нитроатроароматические соединения

Abstract

A number of push-pull dyes based on pyrimidines, bearing various electron-donating carbazole and triphenylamine fragments, have been studied as sensing fluorophores. Fluorescence studies demonstrated that the emission of all derivatives in acetonitrile is sensitive to the presence of some nitroaromatic explosives. A selective fluorescence quenching response, including a sharp color change under UV, makes these fluorophores promising fluorescence sensory materials for nitroaromatic explosives.
