ABSTRACT:The new poly(arylenevinylene) derivative composed naphthalene phenylene vinylene backbone was developed. The theoretical calculation showed that the model compound of the obtained polymer was highly distorted between the stryl and naphthalene units as well as between the backbone and fluorene side units. The polymer was synthesized by the palladium catalyzed Suzuki coupling reaction with 2,6-(1 0 ,2 0 -ethylborate)-1,5-dihexyloxynaphtalene and 1,2-bis(4 0 -bromophenyl)-1-(9 00 ,9 00 -dihexyl-3-fluorenyl)ethene. The structure of the polymer was confirmed by
