2-Fluorophenazine, a accepter unit, was prepared for the synthesis of conjugated polymers for application in organic solar cells. The introduction of a phenazine moiety containing fused phenyl groups is key since it reduces the energy levels of the HOMOs in conjugated polymers. Thus, conjugated polymers containing mono-fluorophenazine, thiophene, and benzodithiophene were synthesized using the Stille coupling reaction to generate PBDT-FPz, PBDT-TFPz, and PBDT-DTFPz, and their HOMO energy levels were determined to be − 5.86, − 5.76, and − 5.60 eV, respectively. The device based on PBDT-DTFPz:PC₇₁BM exhibited the photovoltaic performance of 1.69%.

2-氟吩嗪是一种受体单元，用于合成用于有机太阳能电池的共轭聚合物。引入含有稠合苯基的吩嗪部分是关键，因为它降低了共轭聚合物中 HOMO 的能级。因此，使用 Stille 偶联反应合成了含有单氟吩嗪、噻吩和苯并二噻吩的共轭聚合物，生成PBDT-FPz、PBDT-TFPz和PBDT-DTFPz，它们的 HOMO 能级确定为 - 5.86、 - 5.76、和 - 5.60 eV，分别。基于PBDT-DTFPz :PC ₇₁ BM 的器件表现出 1.69% 的光伏性能。
