Abstract

Pseudo-regular alternating PDPP-TVS copolymers using an asymmetric monomer (thiophene-vinylene-selenophene (TVS)) are synthesized. Unlike regular alternating copolymers, these polymers are highly soluble in nonchlorinated solvents such as tetra-hydrofuran, toluene, xylene, and tetralin. The organic field-effect transistor devices fabricated using these polymers dissolved in nonchlorinated solvents exhibit a high hole mobility up to 8.2 cm(2) V(-1) s(-1).
