Understanding the complex photophysics of covalent photosensitizer–catalyst (PS–CAT) dyads is the basis for advanced structure and reactivity design. Here, we compare the light-induced processes of two PS–CAT hydrogen evolution dyads which differ in the chemical linkage between the Ir photosensitizer and the polyoxometalate catalyst. Variation of the linkage structure results in major changes of the photophysical properties and deactivation pathways which could be one of the factors controlling the catalytic activity.

有机键控制共价光敏剂-多金属氧酸盐氢析出二价体的光物理性质

了解共价光敏剂-催化剂（PS-CAT）二元化合物的复杂光物理特性是高级结构和反应性设计的基础。在这里，我们比较了两种PS-CAT析氢双光的光诱导过程，它们在Ir光敏剂和多金属氧酸盐催化剂之间的化学键不同。键结构的变化导致光物理性质和失活途径的重大变化，这可能是控制催化活性的因素之一。
