A Pseudo-Regular Alternating Conjugated Copolymer Using an Asymmetric Monomer: A High-Mobility Organic Transistor in Nonchlorinated Solvents.

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 tetrahydrofuran, 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).
