Patent ID: 8519068

Claim:
A 2,7-carbazole-containing conductive polymer represented by the following formula 1: wherein 1 is the molar fraction of monomer X and is 0.41 ≤ l l + m + n < 1 , m is the molar fraction of monomer Y and is 0 < m l + m + n ≤ 0.50 , n is the molar fraction of the carbazole and is 0 < n l + m + n ≤ 0.09 , each of X and Y is a monomer structure having a donor, acceptor or light absorption function, and R 1 is C 1 -C 20 alkyl, C 1 -C 20 alkoxy, C 3 -C 20 cycloalkyl, C 1 -C 20 heterocycloalkyl, aryl, heteroaryl, CN, C(O)R, or C(O)OR, wherein R is C 1 -C 20 alkyl, C 1 -C 20 heterocycloalkyl, aryl, or heteroaryl.
