摘要

我们报告了一种光响应四面体金属有机胶囊，该胶囊结合了过铼酸盐催化剂，在 350 纳米光照射下，过铼酸盐催化剂被选择性释放，从而开启了氢硅烷对有机羰基的催化还原。在 75 °C 下加热 2.5 小时可关闭催化活性，从而促进胶囊重整和催化剂重新封装。该催化剂可进行多次开关循环，产品产量与光照时间之间的关系非常明显。因此，封装可以将光响应性与催化作用结合起来，并可推广到其他催化剂和胶囊中。

Light-Responsive Aldehyde-Reduction Catalysis Through Catalyst Encapsulation

We report a light-responsive tetrahedral metal–organic capsule that binds a perrhenate catalyst, which is released selectively upon irradiation with 350 nm light, turning on the catalytic reduction of organic carbonyls by hydrosilanes. The catalytic activity can be switched off by heating at 75 °C for 2.5 h, which stimulates capsule reformation and catalyst re-encapsulation. Multiple on-off cycles were shown, with a clear relationship between product yield and light irradiation time. Encapsulation thus enables the coupling of light-responsiveness to catalysis in a manner that might be generalized to other catalysts and capsules.
