Molecular Engineering of Conjugated Polymers for Solar Cells and Field-Effect Transistors: Side-Chain Versus Main-Chain Electron Acceptors

Two model polymers, containing fluorene as an electron-donating moiety and benzothiadiazole (BT) as an electronaccepting moiety, have been synthesized by Suzuki coupling reaction. Both polymers are composed of the same chemical composition, but the BT acceptor can be either at a side-chain (i.e., S-polymer) or along the polymer main chain (i.e., M-polymer). Their optical, electrochemical, and p...
