Abstract
We synthesized a new ether-type PPV copolymer (C10-PPV) containing dibenzothiophene-5,5-dioxide in the main chain and characterized by IR, NMR, UV-Vis, fluorescence, cyclic voltammetry, TGA, DSC measurements. The polymer is readily soluble in common organic solvent. It emits blue light in CHCl3 solution, and its quantum efficiency (Φpl) is 58%. The cyclovoltammetric investigation reveals that C10-PPV possesses high electron affinity (EA=3.36 eV) and high ionization potential (IP=6.24 eV). A single-layer light emitting diode (LED) with the configuration of ITO/C10-PPV/Al was fabricated. The LED shows a turn-on voltage at 11 V and emits blue–green light with a peak at 508 nm.
