Bruma // Nanomaterials: Applications & Properties (NAP-2012) : 2-nd International conference, Alushta, the Crimea, September 17-22, 2012 / Edited by: A.

Abstract The paper describes the synthesis and characterization of three copolymers containing perylenediimide units and other chromophores in the main chain, as well as various flexible groups as siloxane, hexafluoroisopropylidene or ether, with emphasis on their thermal and photo-optical properties. Very thin copolymer films were obtained from these polymers with smooth and homogeneous surfaces that are self-organized into vertically segregated structures. Upon irradiation with light of different wavelengths the polymers in solution showed photoluminescence maxima in the UV, blue or green-yellow spectral range. In solid state only a weak emission in the UV domain occurred due to aggregation of perylenediimide cromophores which leds to fluorescence quenching. The FRET phenomenon between oxadiazole to perylene-diimide chromophores was observed to occur for which the oxygen bridge appear to be responsible.
