Pyrene-Incorporated Side Chain in π-Conjugated Polymers for Non-Volatile Transistor-Type Memory Devices with Improved Stretchability

The direct application of a conjugated polymer as the single active layer in a field-effect transistor (FET) memory device is in high demand to integrate the conventional charge-transport and charge-storage layer. To achieve this goal, we report side-chain-engineered donor (D)–acceptor (A)-type conjugated copolymers with a D moiety of bithophene (2T) and an A moiety of diketopyrrolopyrrole (PDPP2T). Pyrene (PY)-incorporated side chains serving...
