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.
