Incorporation of polycyclic azaborine compounds into polythiophene-type conjugated polymers for organic field-effect transistors.

A thiophene-fused polycyclic azaborine skeleton was employed into conjugated polymers for organic field-effect transistors for the first time. Two polythiophene-type polymers were developed, which exhibited low HOMO levels and strong intermolecular interactions, leading to a hole mobility of up to 0.38 cm(2) V(-1) s(-1).
