Photoresponsive spiropyran-functionalised MOF-808: postsynthetic incorporation and light dependent gas adsorption properties

The first example of spiropyran (SP) functionalised metal–organic framework (MOF) was synthesised via a two-step post-synthesis modification of the Zr-oxo nodes in MOF-808. The resulting MOF-808-SP showed photoresponsive surface area, pore volume and CO 2 uptake.
