摘要/Abstract

摘要： 氮杂芪(azastilbene)衍生物及其盐类,是一类重要的功能化合物,和普通的芪类化合物相比,它的光谱响应范围可以大幅度地移向长波区。同时它具有很强的分子可极化率,对外场作用响应灵敏。

Abstract: Five 2-4’-formyl styrylbenzothiazoline compounds (FSBT) were synthesized and their spectral characteristics were studied. The results indicate that FSBT compounds possess a good spectral response at visible region which varies remarkably with different counter ions. The intermolecular aggregation of FSBT is easily formed at high concentration of aqueous solution. New absorption and emission peaks of aggregates were observed at long wavelengths by the second-order derivative absorption spectra and the fluorescence spectra. This property is very important to enhance the photosensitivity.

Key words: azastilbene derivatives, aggregate state, spectral characteristics
