BLUE ORGANIC ELECTROLUMINESCENT POLYMER HAVING 9,10-DIPHENYLANTHRACENE AND ELECTROLUMINESCENCE DEVICE USING THE POLYMER

摘要

PURPOSE: A blue organic electroluminescent polymer having 9,10-diphenylanthracene and an electroluminescence device using the polymer are provided, to improve the heat stability and the luminescence efficiency by preventing the deterioration of luminescence characteristic due to the π-stacking of an organic layer forming material. CONSTITUTION: The blue organic electroluminescent polymer has 9,10-diphenylanthracene and vinylene as a main chain and is represented by the formula 1, wherein Ar1 and Ar3 are independent each other and are an arylene group of C6-C30 substituted with an alkoxy group of C1-C25 substituted with an unsaturated alkyl group of C1-C25; an arylene group of C10-C24 having the fused aromatic ring; an arylene group of C6-C30 substituted with an alkylamino group of C1-C25 or an arylamino group of C6-C30; a carbazole derivative having an alkyl group of C1-C25 or an aryl group of C6-C30; a fluorenyl group having an alkyl group of C1-C25, a polyalkoxide group of C1-C25 or an aryl group substituted with an alkyl or alkoxy group of C1-C25, at the C-9 position; a silylene group substituted with an alkyl group of C1-C25, an alkoxy group of C1-C25 or an aryl group of C6-C30; or an arylene group having a silyl group substituted with an alkyl group of C1-C25, an alkoxy group of C1-C25 or an aryl group of C6-C30, Ar2 and R is independent each other and are H, an aryl group of C6-C30 substituted with an alkoxy group of C1-C25 substituted with an unsaturated alkyl group of C1-C25; an aryl group of C10-C24 having the fused aromatic ring; an aryl group of C6-C30 substituted with an alkylamino group of C1-C25 or an arylamino group of C6-C30; a carbazole derivative having an alkyl group of C1-C25 or an aryl group of C6-C30; a fluorenyl group having an alkyl group of C1-C25, a polyalkoxide group of C1-C25 or an aryl group substituted with an alkyl or alkoxy group of C1-C25, at the C-9 position; a silyl group substituted with an alkyl group of C1-C25, an alkoxy group of C1-C25 or an aryl group of C6-C30; an aryl group having a silyl group substituted with an alkyl group of C1-C25, an alkoxy group of C1-C25 or an aryl group of C6-C30; or a cyano group or a fluoro group, l is an integer of 1-100,000, m is an integer of 0-50,000, l is equal to or larger than m, and n is an integer of 1-100,000.
