2,6-Bis(trimethytin)-4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b’]dithiophene has been used for the synthesis of small molecules and low band gap polymer semiconductors such as PTB-7, PCE10 (also called PTB7-Th or PBDTTT-EFT) and PBDB-T (PCE12) for OFETs, OLED, PLED, OPV applications.
Bearing two ethylhexyl alkyl side chains, with fused thiophenes and thiophenes as electron-rich pendants, 2,6-bis(trimethytin)-4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b’]dithiophene offers good solubility for synthesis of polymer chains.
