Anthracene-[1]benzothieno[3,2-b][1]benzothiophene (BTBT) dyad and triads as p-type semiconductors for organic field-effect transistors and phototransistors

Abstract

[1]Benzothieno[3,2-b][1]benzothiophene (BTBT) and anthracene (An) are the most promising planar building blocks for constructing p-type small molecules for high-performance organic field-effect transistors (OFETs).
