首次制备了二氮杂卟啉-C60连接二联体来评估二氮杂卟啉的固有电子转移性质。该二联体显示出有效的电荷分离态的形成，其寿命比具有相同间隔基的相应卟啉-C60连接的二联体的寿命长4倍。与此延伸一致，与卟啉-C60二元体相比，用二氮杂卟啉-C60二元体修饰的SnO 2纳米结构电极也显示出可见光区光电流的产生增强。这些结果表明，二氮杂卟啉是非常有前途的建筑砌块的建设人工光合作用和太阳能转换。
Diazaporphyrin-C60 linked dyad has been prepared to assess intrinsic electron transfer properties of diazaporphyrins for the first time. The dyad exhibited the efficient formation of a charge-separated state which has a lifetime 4× longer than that of the corresponding porphyrin-C60 linked dyad with the same spacer. In accordance with this elongation, a SnO2 nanostructured electrode modified with the diazaporphyrin-C60 dyad also revealed enhanced photocurrent generation in the visible region in comparison with that with the porphyrin-C60 dyad. These results show that diazaporphyrins are highly promising building blocks for the construction of artificial photosynthesis and solar energy conversion.
