Synthesis of Phenylenevinylene Oligothiophene Derivatives with and without Cyano Side Substitution and Evaluation of Optoelectronic Characteristics
Two types of phenylenevinylene terthiophene with and without cyano side substitution were synthesized to investigate the effect of the molecular structure on optoelectronic properties. The oligothiophene with cyano side substitution exhibited large bathochromic effect and behaved as organic electron acceptors with decrease in field effect conductivity due to increase in dipole moment.
