开发了一种带正电荷的氧化还原活性金属-有机三角形，含有三个氧化还原活性铜中心，通过弱的主客体相互作用将阴离子有机染料（荧光素）包封用于光催化制氢。独特的几何形状强制适用于质子还原的扭曲正方形平面配位。用单核铜络合物作为参考光催化剂和无活性的ATP作为抑制剂进行对照实验，以证实这种酶的光催化行为。
A positively charged redox-active metal–organic triangle containing three redox-active copper centres was developed to encapsulate anionic organic dyes (fluorescein) through a weak host–guest interaction for photocatalytic hydrogen production. The unique geometry enforces a distorted square planar coordination suitable for proton reduction. Control experiments with a mononuclear copper complex as a reference photocatalyst and inactive ATP as an inhibitor were performed to confirm this enzymatic photocatalytic behaviour.
