Description and Uses

Thieno[3,2-b]thiophene, also known as thienothiophene (TT), is a heterocyclic compound. It belongs to the family of fused thiopehenes and is widely used as an intermediate for the synthesis of small molecules and polymers in the application of organic field-effect transistors (OFETs) and organic photovoltaic devices (OPV).

TT may be used as conjugated side chains in the synthesis of donor-acceptor copolymers. It finds potential applications in the enhancement of power conversion efficiency (PCE) for organic solar cells.
