文摘

•: Two new polymers were made by inserting DPPD unit on P(BDT-TDPPDT) and P(BDTT-TDPPDT).
•: The property modulation of the new polymers was systematically examined.
•: New polymers showed higher band gaps than those of the original polymers.
•: New polymers showed similar HOMO levels with those of the original polymers.
•: New polymers showed improved morphology when blended with PC₇₀BM.
