Abstract Photochromic molecules have been considered to be applied in responsive functional materials. Recently, the combination of a porous host matrix and these photoactive species has become an emerging field of research. Especially the use of crystalline nanoporous metal-organic frameworks (MOFs) as host materials has proven to be very promising. The combination of crystallinity and the ability to be systematically functionalized is one of the main advantages of these porous host materials. The resulting switch@MOF hybrid systems exhibit fascinating and even surprising properties ranging from the “simple” possibility of solid-state switching to remote control gas uptake and conductance photoswitching. After a short
