DTS-EH-Sn, for the synthesis of low bandgap semiconducting polymers

High quality monomer for applications in OLED, OPV and OFET devices

DTS-EH-Sn, namely 4,4'-Bis(2-ethylhexyl)-5,5'-bis(trimethyltin)-dithieno[3,2-b:2,3-d]silole, is the intermediate for the synthesis of low bandgap semiconducting polymers such as PSBTBT and PBBTSiD which are widely used in OLED, OPV and OFET devices.

Compared to C-C bond, C–Si bond has larger bond length which could result in improved π-π stacking of the molecules. The greater C-Si bond length also can reduce steric hindrance from the bulky alkyl side chains thereby to increase semi-crystallinity of the polymers containing dithienosilole (DTS) unit in their backbones.
