摘要
In this work, we report the synthesis and characterization of wholly aromatic polyoxadiazoles containing 3,4-alkylenedioxythiophenes. The polymers are synthesized using the precursor polyhydrazide route. The polymers have well-defined structures and exhibit good thermal stability with the onset decomposition temperature in nitrogen at around 330 degreesC. These polymers are characterized by FTIR, 1 H NMR, UV-Vis and fluorescence spectroscopy. Electrochemical properties of these polymers are studied using cyclic voltammetry. Polyoxadiazoles based on 3,4-alkylenedioxythiophenes exhibit good hole-blocking properties. (C) 2002 Elsevier Science B.V. All rights reserved.
