Synthesis and Characterization of Small Functional Molecule Composed of BseDz

摘要

Novel organic conjugated molecule composed of central benzoselenadiazole (BseDZ) units as electron acceptor and two pyrrole groups as electron donors was prepared via the Stille coupling reaction. The molecular structure was verified by ~1HNMR and ~(13)CNMR. UV-vis spectroscopy showes that molecule has broad absorption spectrum and a low band gap by theoretical calculation, The fluorescence spectra exhibit strong emission peaks in the organic light regions. Cyclic voltammetry exhibited that molecule have reversible redox curve, property of electrochemical is stable. which suggest that it has potential application value in photovoltaic material.
