POLYMERIC COMPOUNDS CONTAINING PHENYLCARBAZOLE GROUP AND POLYMER LIGHT EMITTING DIODE EMPLOYING THE SAME

摘要

A polymer compound having a phenylcarbazole group, and a polymer electroluminescent device containing the polymer compound are provided to improve hole and electron transport property and to enhance brightness and color reproduction range. A polymer compound having a phenylcarbazole group is represented by the formula 1, 2 or 3, wherein R1 to R11 are identical or different one another and are H, a halogen atom, an alkyl group, an alkoxy group, a cyano group, a nitro group, an acyl group, a substituted or unsubstituted amino group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted hetero ring having at least one halogen, nitrogen, oxygen or sulfur atom as a ring member; X1 to X4 are identical or different one another and are an alkylene group, a substituted or unsubstituted arylene group, a substituted or unsubstituted hetero arylene group, or their combination; Y1 to Y3 are a substituted or unsubstituted C6-C60 aryl group, a substituted or unsubstituted C3-C60 heteroaryl group, or a substituted or unsubstituted fluorene group; a, b, c and d are 0 or 1; and n, m and p are an integer of 1-50,000.
