摘要: In this work we report the synthesis and characterization of processable poly(aromatic oxadiazole)s. The polymers are rendered by either dissolving polymer in strongly acidic organic solvent or thermal conversion a soluble precursor polyhydrazide. optical charge transporting properties have been investigated UV-Vis absorption, photoluminescence spectroscopy cyclic voltammetry. All found to exhibit strong purple-blue fluorescence good hole-blocking electron-injecting properties.
