Abstract
Poly (3-bromothiophene) was prepared by FeCl3 oxidative polymerization. UV-Vis spectrum, fluorescence spectrum, photoluminescence (PL) spectrum and cyclic voltammograms of poly (3-bromothiophene) were recorded.The maximum absorption peak at 380 nm and the maximum emission peak at 504 nm. Scanning electron microscope (SEM) of poly (3-bromothiophene) shows that its morphology is nanowire structure. Poly (3-bromothiophene) exhibits good electrical properties with conductivity of 0.8 S/cm.The optical band gap, electrochemical band gap, HOMO/LUMO energy were calculated with the value of 2.38 eV,1.99 eV,-5.18 eV and-3.19 eV , respectively.
