• The exploitation of photo-responsive metalorganic frameworks (MOFs) is important in the field of optical switching, advanced detection, and molecular machines. However, it remains challenging due to the heavy dependence on conventional organic photochromic molecules. Herein, a novel photochromic MOF based on benzophenone units, [Zn 4 (μ 2 -O)( 3 -O)(cdip) 2 (DMF)] n (H 4 cdip = 5,5-carbonyldiisophthalic acid) ( 1 ), has been successfully synthesized. Compound 1 exhibits instant and reversible photochromic behavior under 365 nm UV and X-ray irradiation through the radical formation of benzophenone units. Furthermore, the fluorescence of 1 can be reversibly modulated during the photochromic process. The excellent stability and reproducibility make it suitable for inkless erasable printing paper. A novel photochromic MOF ( 1 ) based on benzophenone units has been successfully synthesized. 1 shows distinct photochromic behavior under ultraviolet and X-ray irradiation. And the printing paper coated with 1 exhibits good resolution and stability.
