Abstract

Abstract : Halogen-bridged photochromic metal–organic frameworks have been reported, and one can exhibit photomodulated luminescence featuring a non-destructive readout capability. Abstract : Two isomorphous halogen-bridged metal–organic frameworks have been solvothermally synthesized based on the bipyridinium ligand and structurally characterized. The two compounds show an eye-detectable color development upon light irradiation, but different coloration degrees. The relationship between the structure and photosensitivity has been studied in detail. The photochromic properties of the bipyridinium unit have been used to modulate the luminescence under light illumination. Compound1 is the first example showing photo-modulated luminescence switching featuring a non-destructive readout capability based on transition metals.
