Description

General description

5,5′′′′′-Dihexyl-2,2′:5′,2′′:5′′,2′′′:5′′′,2′′′′:5′′′′,2′′′′′-sexithiophene (DH6T) is an alkyl substituted oligothiophene that can be used as an organic semiconductor. It has a field mobility of 1 cm²/Vs that makes it a suitable active layered material in electronic and optoelectronic applications.

Application

DH6T can be used as a p-type donor molecule for the fabrication of organic electronic devices such as organic field effect transistors (OFETs), thin film transistors (TFTs) and organic solar cells (OSCs).
