Description

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

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.

Packaging

1, 5 g in glass bottle
