Reversible single-crystal-to-single-crystal conversion of a photoreactive coordination network for rewritable optical memory storage

Reversible single-crystal-to-single-crystal photocyclization–cycloreversion reaction of a stilbene-based coordination network exhibits a conspicuous fluorescence change. The controllable fluorescence and high fatigue resistance feature of this bistable material make it a single-crystalline device for applications in rewritable optical memory storage systems.
