文摘

A series of low–band gap conjugated polymers P1–P3 have been synthesized. All polymers exhibited good solubility in common organic solvents. Fluorinated BTZ units play important roles in ICT and photovoltaic performance. Optical and electronic energy levels could be tuned. Polymer P3 exhibited the highest PCE value of 3.00% with PC71BM.
