Four novel heteroleptic Cu(I) photosensitizers with 3,8‐diaryl‐2,9‐diisopropyl‐1,10‐phenanthroline derivatives as electron‐donating bidentate N‐ligands have been designed and synthesized. The metal copper complexes are studied in light‐driven water reduction system. And the substituent effect at the 3,8‐positions of N‐ligands impacting on photosensitive activity and photoelectric chemical properties are explored and discussed. Surprisingly, with the enhancement of electron‐donating capacity of substituent group at 3,8‐sites of 1,10‐phenanthroline, the photosensitive activity of photosensitizer linearly increases, and photocatalytic performance up to 817 turnover numbers (TON) was reached combining with water reduction catalyst (WRC), Fe3(CO)12. The photocatalytic performance of these photosensitizers dramatically increased compared to 2,9‐diispropyl‐1,10‐phenanthroline complex (TON = 89). Moreover, the introduction of methoxy substituent to copper complexes, which could increase the fluorescence lifetimes (τmax = 209 ns) and promote hydrogen evolution.

含3,8-双取代邻菲咯啉的杂铜（I）光敏剂：合成，光物理性质和光催化从水中析出氢
设计并合成了四种新型的具有3,8-二芳基-2,9-二异丙基-1,10-菲咯啉衍生物作为供电子二齿N-配体的Cu（I）杂合光敏剂。在光驱动水还原系统中研究了金属铜配合物。并探讨了N配体3,8位上的取代基对光敏活性和光电化学性能的影响。令人惊讶的是，随着在1,10-菲咯啉的3,8位上取代基的给电子能力的增强，光敏剂的光敏活性线性增加，与水结合使用时，光催化性能达到817周转数（TON）。还原催化剂（WRC），Fe 3（CO）12。与2,9-二异丙基-1,10-菲咯啉配合物（TON = 89）相比，这些光敏剂的光催化性能显着提高。此外，引入甲氧基取代基的铜配合物，这可能会增加荧光寿命（τ最大= 209纳秒），并促进析氢。
