A luminescent bipolar polymer containing 1,3,4‐oxadiazole and triphenylamine has been synthesized. A smooth and dense thin film of polymer is easily obtained by spin coating its chloroform solution. This film exhibits a strong blue fluorescence under the irritation of ultraviolet (UV) light. The synthesized polymer possesses a high glass transition temperature ( T g ) of 167°C. A single‐layer electroluminescence (EL) device indium‐tin oxide (ITO)/polymer/Mg:Ag emitted blue light with a turn‐on voltage of 13 V. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 88:50–53, 2003
