Photoswitchable metal-organic frameworks (MOFs) enable the dynamic remote control of their key properties. Here, a readily producible approach is presented where photochromic molecules, i.e. azobenzene (AB) and o-tetrafluoroazobenzene (tfAB), are loaded in MOF films of type HKUST-1. These nanoporous films, which can be reversibly switched with UV/visible or only visible light, have remote-controllable guest uptake properties.
可光开关的金属有机框架（MOFs）能够对其关键特性进行动态远程控制。在此，我们提出一种易于制备的方法，即将光致变色分子，即偶氮苯（AB）和邻四氟偶氮苯（tfAB），负载到HKUST-1型MOF薄膜中。这些纳米多孔薄膜可以通过紫外光/可见光或仅可见光进行可逆切换，具有可远程控制的客体吸附特性。
