2,6-bis(trimethytin)-4,8-bis(5-(2-ethylhexylthio)-4-fluorothiophen-2-yl)benzo[1,2-b:4,5-b’]dithiophene (BDTTDSFSn) is an electron-rich building block that has been used for the synthesis of small molecules and low band-gap polymer semiconductors for highly efficient OSCs and OPV applications.

Bearing two ethylhexyl thioalkyl side chains, with fused thiophenes and thiophenes as electron-rich pendants, BDTTDSFSn offers good solubility for the targeted compounds. The introduction of the fluoro atoms on the side thiophene rings can also lower the HOMO/LUMO energy levels of the desired polymers.
