2,2'-bithiophene-5-carbonitrile


Product Code B311
Price £253.00 ex. VAT

2,2'-bithiophene-5-carbonitrile is the intermediate used for the synthesis of 3,6-bis[5-(2,2'-bithiophene)]pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione which can be further modified to form oligomers or polymers used for organic electronic devices.

2,2'-bithiophene unit is electron-rich, and thus a good building block for the synthesis of semiconducting materials that are used for organic electronic devices. Embedded in the polymer backbones, 2,2'-bithiophene unit is proven to promote cystallinity to form small domains in bulk heterojunction solar cells [4].

Synthesis of 3,6-bis[5-(2,2'-bithiophene)]pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione.
