摘要：

The synthesis of an ambipolar pi-conjugated copolymer consisting of alternating diketopyrrolopyrrole and tetrafluorobenzene via direct arylation polymerization (DAP) is reported. Two different combinations of monomers are investigated under various catalytic conditions for DAP. The target polymer obtained under an optimized catalytic condition shows minimal structural defects, a number-average molecular weight of 33.2 kDa, and balanced electron and hole mobility of 1 x 10(-2) cm 2 V-1 S-1 in the organic field-effect transistors fabricated and tested under ambient conditions.
