Novel photoluminescent donor–acceptor poly( p ‐phenylenevinylene)‐type conjugated polymers containing thiophene and 1,3,4‐thiadiazole units in the main chain were synthesized from 2,5‐bis(5‐bromomethyl‐2‐thienyl)‐1,3,4‐thiadiazole and 1,3/1,4‐benzenedialdehyde by Wittig–Horner reaction. The synthesized polymers were characterized by the use of thermal analysis and spectroscopic (infrared, UV‐visible absorption, and photoluminescence) measurement. The resultant material exhibited bluish green, green, and orange fluorescence in their solution and thin film and solid forms, respectively. The redox property of the polymers has also been studied by cyclic voltammetry. The optical and electrochemical studies reveal that these novel polymers are new promising materials for the development of efficient polymer light‐emitting diodes. © 2012 Wiley Periodicals, Inc.
