设计并合成了一种新型的锌酞菁-锌卟啉二元化合物(1)，其中锌的卟啉部分与ABAB型的锌酞菁部分共价连接。ZnPc-ZnPor dyad1可以在很宽的可见光光谱范围内吸收。荧光光谱分析表明，锌卟啉与锌酞菁之间存在分子内有效的能量转移。当将dyad1用作染料敏化太阳能电池的捕光敏化剂时，经dyad1敏化的电池在模拟空气质量为1.5的全日照下的功率转换效率为2.7 %。Diad1电池的入射光子-电流效率谱表明，dyad1中的两个组分对当前一代的贡献。
A novel Zn phthalocyanine‐Zn porphyrin (ZnPc‐ZnPor) dyad (1), in which a zinc porphyrin moiety is linked covalently with an ABAB‐type zinc phthalocyanine moiety, has been designed and synthesized. The ZnPc‐ZnPor dyad1can absorb over a wide spectral range of visible light. The fluorescence spectrum of dyad1revealed an intramolecular efficient energy transfer from Zn porphyrin to Zn phthalocyanine. When dyad1was used as a light‐harvesting sensitizer for dye‐sensitized solar cells, the cell sensitized by dyad1provided a power conversion efficiency of 2.7 % under simulated air mass 1.5 global sunlight. The incident photon‐to‐current efficiency spectrum of the dyad1cell suggested the contribution of both components in dyad1for the current generation.
