Thieno[3,2-b]thiophene Chemical Properties,Usage,Production

General description

Thieno(3,2-b)thiophene (TT) is an electron rich conjugated polymer that has a quinoidal structure with a narrow band gap. It facilitates a strong intermolecular networking.

Application

Thieno[3,2-b]thiophene 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.

Classification

Thiophene, Fused thiophene, Dithiapentalene, Heterocylic aromatics, Five-membered ring, Semiconductor synthesis intermediates, Low band gap polymers OFETs, Organic Photovoltaics, Polymer solar cells

preparation

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).
Fused thiophenes are more electron-rich and more structurally rigid, with extended π-conjugation so they are good candidates for adjusting the band gap of the organic polymer semiconducting materials, i.e. Poly[2,5-bis(3-hexadecylthiophen-2-yl)thieno[3,2-b]thiophene] (also known as PBTTT).
