2,5-bis(trimethylstannyl)thieno[3,2-b]thiophene can be prepared by using thieno[3,2-b]thiophene as starting material, further reaction with dibromo compounds (Stille Coupling) to form oligomers or polymers which can be used for organic electronic devices.

Thienothiophene is fused with extend conjugation over two thiophene rings. Thienothiophene is proven to be a good candidate for the materials that are used for Organic Field Effect Transistors, Sensors and OPV devices. Thienothiophene provide further tuning of energy gap of polymer materials with higher electron density over the conjugated ring systems.

DPPT-co-TT synthesis with 2,5-bis(trimethylstannyl)thieno[3,2-b]thiophene and 3,6-bis(5-bromothiophen-2-yl)-2,5-bis(2-octyldodecyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione via Stille Coupling polymerisation

Note: This product has been used in our own lab by Ossila chemists for the synthesis of DPP-DTT (high mobility p-type polymer), one of our most popular products for optoelectronic devices.
