DESIGN AND SYNTHESIS OF POLYMERS FOR LIGHT-EMITTING-DIODES

Polymers with aromatic phi-conjugated moieties were utilized as electr oluminescent materials. In order to meet the requirements for light-em itting diodes (LED), the design and synthesis of electroluminescent po lymers had to be developed and viewed in this review. Focus is on poly mers with arylene vinylene, arylene ethinylene, phenylene, thiophene a nd arylene amine moieties as light-emitting, hole-transporting and ele ctron-transporting materials in LED devices. An attempt has been made to arrange a structural classification of electroluminescent polymers in nonsegmented and segmented polymers. (C) 1998 John Wiley & Sons, Lt d.
