The present invention provides PHPIT and fabrication thereof. PHPIT has a side-chain-tethered with hexylphenanthrenyl-imidazole polythiophene. The visible light absorption of the PHPIT/PCBM blend is enhanced by the presence of the electron-withdrawing hexylphenanthrenyl-imidazole. The PHPIT/PCBM blend experienced more-balanced electron and hole mobilities and solvability.
本发明提供了
PHPIT及其制备方法。
PHPIT具有侧链与己基
酚菲-
咪唑聚
噻吩相连。由于存在电子受体的己基
酚菲-
咪唑,
PHPIT/PCBM混合物的可见光吸收得到增强。
PHPIT/PCBM混合物具有更平衡的电子和空穴迁移率以及可溶性。
