Abstract:
1. An electroluminescent device, comprising a) a spaced-apart anode and cathode; and b) an organic layer disposed between the spaced-apart anode and cathode and including a conjugated polymer having an azole structure represented by formula (I) wherein: Z is NR′, or S; Q represents atoms necessary to complete a hetero ring with N and Z; R is a substituent and selected from hydrogen, or alkyl, or alkenyl, or alkynyl, or alkoxy wherein the alkyl, alkenyl, alkynyl or alkoxy can have from 1 to 40 carbon atoms; or aryl from 6 to 60 carbon atoms; or heteroaryl from 4 to 60 carbons; or F, or Cl, or Br; or a cyano group; or a nitro group; or atoms coupled to N or Z to complete a fused aromatic or heteroaromatic ring; and R′ is hydrogen, or alkyl, or alkenyl, or alkynyl of from 1 to 40 carbon atoms wherein the alkyl, alkenyl, alkynyl or alkoxy can have from 1 to 40 carbon atoms; aryl from 6 to 60 carbon atoms; or heteroaryl from 4 to 60 carbons; or F, or Cl, or Br and wherein the conjugated polymer including formula (I) is represented by the repeating unit of formula (III) wherein: X is a conjugated group of 2 to 60 carbon atoms; Ar is an aryl group having 6 to 60 carbon atoms; or heteroaryl having 4 to 60 carbon atoms, and one or more N, S, or O atoms; and L is a direct bond between Formula (I) and Ar or a carbon linking group having 1 to 40 carbon atoms or a non-carbon linking group having 0 to 40 carbon atoms.
