- Abstract
A series of new copolymers with unsaturated-linker-containing donors and benzobisthiadiazole acceptors are synthesized. Two kinds of side chains (2-octyl-1-dodecyl chain and siloxane-terminated hexyl chain) are added to the polymer backbone. The introduction of unsaturated-linker-containing donor enhances the rigidity of the copolymers. The strong electron-withdrawing benzobisthiadiazole units make these copolymers display very narrow bandgaps in the range of 0.75-1.26 eV. Bottom-gate and bottom-contact transistors based on these polymers exhibit p-type field-effect behavior with hole mobilities up to 1.17 x 10-3 cm² V-1 s-1.
