Overview

Description

Thieno[3,2-b]thiophene-2,5-diboronic acid bis(pinacol ester) is a charge transport material commonly used in thin film transistors. They have very high carrier mobility because of the conjugation of the fused ring system and also due to the high concentration of sulphur atoms. The boronic acid ester group improves the solubility and also enhances the charge transport properties.Used as a charge transport material in field effect transitors.
