Synthesis of PQ with its Redox Properties

Pratima V. Damre | Dr. V. M. Raut

Abstract: The thermal, electrochemical, photophysical, and electroluminescent properties of the new polyquinolines varied with the arylene linkage, including p-phenylene, 4, 4'-biphenylene, stilbene, 5, 5'-bithienylene, bis (thienyl)vinylene, and3, 7-phenothiazinylene. The new conjugated polymers combined high glass transition temperature (110-254 ?C) with quasireversible electrochemical reduction from which 2.72-3.00 eV electron affinities were estimated. The optical band gap varied from 2.19 to 2.86 eV whereas the photoluminescence emission maximum varied from blue-green (477 nm) to deep red (646 nm). Some of the new polymers with alternating donoracceptor architecture showed strong intramolecular charge transfer.
