PBBTSiD (CAS number 1334032-16-4) is a small bandgap copolymer (Eg = ~ 0.7 eV ) with a backbone alternating electron donating dithienosilole (DTS) and electron accepting fused-ring benzobisthiadiazole (BBT) units.

The balanced ambipolarity of the BBT moiety of the polymer makes PBBTSiD a good candidate for logic circuit applications. Integrating BBT backboned semiconducting polymers into the bottom gate/top contact TFTs resulted in balanced ambipolar performances with the high µh and µe charge mobility values.
