| [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).
