摘要
Two conjugated polymers using 5,6-dialkoxy benzothiadiazole derivatives as the dopant were synthesized and studied as electroluminescent materials. These two polymers were well characterized by H-1 NMR, UV-Vis absorption spectrum, gel permeation chromatography, fluorescent spectrum and cyclic voltammetry. The electron mobility and electroluminescent properties were also investigated. The highest external quantum efficiency and luminous efficiency were improved by two orders of magnitude facilely via incorporating benzothiadiazole unit in the main chain.
