基于噻吩光电小分子的合成和性能
Synthesis and characterization of small photoelectric molecules composed of thiophene units
摘要
Abstract
Organic conjugated molecule composed of central butoxybenzoselenadiazole (BseDZ) units as electron acceptor and thiophene groups as electron donors was prepared via the Stille coupling reaction. Structure and photoelectric properties of molecule were investigated. The test results of 1H NMR and 13C NMR were consistent with the theory. UV-vis spectroscopy showed that molecule had broad absorption spectrum (237—464nm) and its fluorescence spectra exhibited strong emission peaks in red light regions either in acetonitrile solution or in PMMA films,which illustrated that target molecule was ideal red light emission materials. The conjugated molecule(2.26eV to 2.33eV) belonged to narrow band gap and exhibited stable redox curve by cyclic voltammetry. The above conclusion suggested that it had a potential application in photoelectric material fields.关键词
