Organic field effect transistors selenophenes

A new class of semiconductors for organic field-effect transistors (FET) has been developed and studied. Thus metalation of the 1,4-dibromobenzene derivative 141, followed by Introduction of the appropriate chalcogens gave the fused systems 142, which displayed promising FET performances, in particular the selenophene derivative <04JA5084>.
