We report the synthesis and electrical property of new quinoxailne based fluorene copolymer. A donor-acceptor (D-A) type copolymer containing phenanthrene based fused-aromatic quinoxaline as the acceptor and fluorene as the donor was synthesized via Suzuki coupling reaction. The polymer was well dissolved in common organic solvents, such as chloroform, THF and chlorobenzene. The number average molecular weight and Polydispersity index of the copolymer was found to be 20,000 g/mol and 1.9. The copolymer showed an absorption band from 300 to 600nm. Detailed results of the solar cells using the polymer will be presented. |
