Polyperyleneimide — Based materials for optoelectronic devices

Abstract

Here we present a study of two copolyimides containing oxadiazole and perylene units in the main chain with emphasis on their photo-optical properties and electrochemical behavior. Upon irradiation with light of different wavelengths these polymers showed photoluminescence maxima in the UV, blue or green-yellow spectral range. Cyclic voltammetry was performed in order to obtain information about the electrochemical behaviour of these polymers that proved their n-type behaviour.
