Paper Abstract

The synthesis and luminescent properties of the homopolymers (4,5) and copolymers (9,10) carrying ion-transporting side chains are reported. When fabricated as alight emitting electrochemical cell the copolymer 10 exhibited a significant reduction in turn-on voltage and improved luminous efficiency compared with a conventionally fabricated polymer light emitting device. Similar results were observed with the pyridine copolymer 13. The model meta-linked trifluoromethyl substituted distyrylbenzene derivative 16 has been synthesized and its crystal structure has been determined with a view to evaluating the related polymers as charge transporting materials.
