Abstract Axially coordinated oligomer of ferrocene based Sn(IV) porphyrin with C60 was synthesized and characterized by the common spectral method and thermogravimetric analysis. The oligomer aggregated into irregular block structure in solid state from observation of scanning electron microscope. According to UV–visible absorption spectra, there was almost no electronic interaction in the ground state among the photoactive components in the oligomer. However, the nanosecond transient absorption spectra and steady-state fluorescence spectra experiments indicated that efficient photoinduced electron transfer among C60, excited Sn(IV) porphyrin, and ferrocene had occurred, which resulted in forming the final charge-separated state with long time of 14 μs in benzonitrile. In addition, a prompt and stable photocurrent was generated in the photovoltaic devices upon irradiation by monochromatic light of λex = 429 nm.

用于光谱和光电流研究的二茂铁基卟啉与富勒烯 C60 的轴向配位低聚物

摘要 合成了具有C60 的二茂铁基Sn(IV)卟啉的轴向配位低聚物，并通过普通光谱法和热重分析进行了表征。低聚物在固态下聚集成不规则块状结构，扫描电镜观察。根据紫外-可见吸收光谱，低聚物中的光活性组分之间在基态下几乎没有电子相互作用。然而，纳秒瞬态吸收光谱和稳态荧光光谱实验表明，C60、激发态的 Sn(IV) 卟啉和二茂铁之间发生了有效的光致电子转移，形成了最终的电荷分离态，时间长达 14 μs 在苯甲腈中。此外，
