Excimer-Type Electroluminescence and Carrier-Transporting Properties of Electron-Accepting π-Conjugated Polymers

Abstract

Rigidly linear and electron-accepting π-conjugated polymers such as poly(pyridine-2,5-diyl), poly(1,10- phenanthroline-3,8-diyl), and poly(4,4 ′ -disubstituted-2,2 ′ -bithiazole-5,5 ′ -diyl) serve as carrier-transporting and light-emitting materials in electroluminescence devices, and they show emission of light which is considered to originate from excimer-type adducts.
