Bistable Solid‐State Fluorescence Switching in Photoluminescent, Infinite Coordination Polymers

Photo-functional infinitely coordinated polymers (ICPs) consisting of the photochromic dithienylethene (DTE) and the luminescent bridging unit to give enhanced fluorescence in the solid state were synthesized. We could fabricate well-ordered micropatterns of these ICPs by a soft-lithographic method, which repeatedly showed high contrast on-off fluorescence switching.
