摘要
Abstract
A novel organic di-Schiff base derivative containing thiadiazole ring, which could be used as photoelectric material, was synthesized. Firstly, the intermediate 5-(p-aminophenyl)-2-amino-l, 3,4-thiadiazole was synthesized through two ways. Although the first way using 4-nitrobenzoic acid as the main raw material had one more step than the second way using 4-aminobenzoic acid as the main raw material, its intermediate yield was 18% higher. The intermediate reacted with 4-methoxybenzaldehyde, and then the target compound 2-(4-p-methoxy-phenyl-methyleneamino)-5-(4-p-methoxy-phenyl-methylene aminophenyl)-1,3,4-thiadiazole was obtained. The target compound was characterized by means of 'H NMR, FTIR and elemental analysis. Its UV-Vis spectrum, photo-luminescent spectrum, cyclic voltammetry curves and TG-DSC curves were studied. The UV-Vis result showed that the maximum absorption wavelength was 374 nm. The photo-luminescent result showed that it could emit blue fluorescence and the maximum emissive wavelength was around 442 nm. The cyclic voltammetry curves indicated that the electron affinity was 2.76 eV and ionization potential was 5.58 eV. The TG-DSC curves revealed its good thermal stability.关键词
