A novel silyl-substituted solvent processable poly(1,4-phenylenevinylene)(PPV) derivative, poly(2-dimethyloctylsilyl-1,4-phenylenevinylene)(DMOS-PPV) is synthesized by the dehyrohalogenation route from 2-dimethyloctylsilyl-1,4-bis(bromomethyl)benzene, and the light-emitting properties of the polymer are studied; single layer electroluminescent devices (ITO/polymer/Ca or Al) exhibit an emission maximum at 520 nm with internal quantum efficiency in the range 0.2–0.3%.
