Rational Optimization of Benzo[2,1‐b;3,4‐b′]dithiophene‐Containing Polymers for Organic Field‐Effect Transistors

Abstract

The rational structure optimization of a polythiophene containing benzo[2,1-b;3,4-b′]dithiophene on the molecular level leads to a polymer that is easily synthesized and processed. Fabricated on a flexible substrate, the polymer shows excellent device characteristics, good reproducibility, and charge-carrier mobilities up to 0.5 cm2 V−1 s−1 without annealing.
