Melting point:260-263°C Molecular Weight:220.26 g/mol

Benzo[1,2-b:4,5-b’]dithiophene is a planar symmetrical molecular structure of the thiophene derivative, enabling a better π-π stacking and good electron delocalization that encourages charge transport. In recent years, it has been intensively studied for the application of OFETs and OPVs. The incorporation of a low-band-gap unit into the benzo[1,2-b:4,5-b’]dithiophene unit could potentially result in a red-shifted absorption due to its electron-rich properties. Benzo[1,2-b:4,5-b’]dithiophene can be chemically modified to fine-tune its chemical structure and electron properties (e.g. band gap), energy levels, and charge mobility of the small molecule/polymers of interest (at a molecular level).

Benzo[1,2-b:4,5-b’]dithiophene (BDT) backboned polymers or small molecules thus provides a relatively better device performance. The following is a good example of a finely tuned structure being synthesised with Benzo[1,2-b:4,5-b’]dithiophene as a starting material.
