Researchers in Sweden have shown that ladder-type polymers, such as poly(benzimidazobenzophenanthroline) (BBL), can successfully work as stable and efficient n-channel material for OECTs. BBL-based OECTs show high transconductance (up to 9.7 mS) and excellent stability in ambient and aqueous media. They have demonstrated that BBL-based n-type OECTs can be successfully integrated with p-type OECTs to form electrochemical complementary inverters. The latter show high gains and large worst-case noise margin at a supply voltage below 0.6 V. Applications of the organic components include logic circuits that can be printed on textile or paper, various types of cheap sensor, non-rigid and flexible displays, and the huge field of bioelectronics… read more.
