本文报道了一系列含磺酸根锚基的铜光敏剂[（sic）Cu（sic）-（SO_3 Na）（2））]（+）。在二氧化钛的存在下，它们形成复合物，其在光驱动的质子还原中是活性光敏剂。这些系统的进一步稳定是通过封装在等离子体聚合的烯丙胺（PPAAm）层。所得PPAAm-CuPS-TiO 2-复合材料在可见光区表现出强吸收。光催化制氢仅使用非贵金属进行。在铁还原催化剂的存在下，获得2452的最大转换数。
A series of heteroleptic copper photosensitizers [(sic)Cu(sic)-(SO3Na)(2))](+) containing sulfonate anchor groups is described. In the presence of titanium dioxide they form composites, which are active photosensitizers in the light driven reduction of protons. Further stabilization of these systems is achieved by encapsulation within a plasma-polymerized allylamine (PPAAm) layer. The resulting PPAAm-CuPS-TiO2-composites exhibit a strong absorption in the visible region of the light. Photocatalytic hydrogen production is performed by using only non-noble metals. In the presence of an iron reduction catalyst a maximum turnover number of 2452 is obtained.
