摘要:
Organic thin film transistors with improved mobility are disclosed. The semiconducting layer comprises a semiconductor material of Formula (I): wherein R1 and R2 are independently selected from alkyl, substituted alkyl, aryl, and substituted aryl; and R3 and R4 are independently selected from hydrogen, alkyl, substituted alkyl, aryl, and substituted aryl. A silanized interfacial layer is also present which has alkyl sidechains extending from its surface towards the semiconducting layer.
摘要:
A polymer comprising one or more types of repeat units, wherein the polymer includes a substituted thieno[3,2-b]thiophene component A and a different component B in the same type of repeat unit or in different types of repeat units, and wherein the polymer excludes a substituted or unsubstituted thieno[2,3-b]thiophene moiety. The polymer can be used as a semiconductor in electronics such as in organic thin film transistors.
