摘要

由熔融苯并噻吩-2-羧酸酯和烷基取代的 2,2′-噻吩-5-羧酸酯合成了一系列 2,5 二基-1,3,4-噻二唑衍生物。对合成化合物的光物理和电化学性质进行了研究。研究发现，取代的 1,3,4-噻二唑的供体分子中共轭链的延长会缩小能带隙，这主要是由于 HOMO 能量的增加。

Synthesis and Photophysical and Electrochemical Properties of Conjugated Donor–Acceptor–Donor Systems Based on 1,3,4-Thiadiazole and Fused Naphtho[2,1-b]thiophene Derivatives

A series of 2,5-diaryl-1,3,4-thiadiazole derivatives have been synthesized from fused benzothiophene-2-carboxylates and alkyl-substituted 2,2′-bithiophene-5-carboxylate. Photophysical and electrochemical properties of the synthesized compounds have been studied. Extension of the conjugation chain in the donor moiety of substituted 1,3,4-thiadiazoles has been found to narrow the energy band gap due mainly to increase of the HOMO energy.
