Dedicated to Professor Waldemar Adam on the occasion of his 80^th birthday

Abstract

A series of donor-π-acceptor (D-π-A) substituted 4-hydroxythiazoles have been synthesized. Electron-donating groups (4-methoxyphenyl and 4-dimethylaminophenyl) were installed in the 5-position of the thiazole; thiophene/pyridine-bridged acceptors (formyl groups and their Knoevenagel condensation products) were placed in the 2-position. The influence of D-π-A character on the photophysical properties and electronic structure was investigated by means of UV/Vis and fluorescence spectroscopy.

抽象的

已经合成了一系列供体-π-受体（D-π-A）取代的4-羟基噻唑。给电子基团（4-甲氧基苯基和4-二甲基氨基苯基）安装在噻唑的5-位；将噻吩/吡啶桥联的受体（甲酰基及其Knoevenagel缩合产物）置于2位。通过UV / Vis和荧光光谱研究了D-π-A特性对光物理性质和电子结构的影响。
