Abstract

Abstract The development of photo‐stimuli‐responsive luminescent materials is essential to address emerging demands in encryption security. Here, a novel photo‐stimuli‐responsive dual‐emitting luminescent material ZJU‐128⊃SP (SP = spiropyran) is reported, which is obtained by encapsulating spiropyran molecules into a cadmium‐based metal–organic framework (MOF), [Cd 3 (TCPP) 2 ]·4DMF·4H 2 O ( ZJU‐128 , H 4 TCPP = 2,3,5,6‐tetrakis (4‐carboxyphenyl)pyrazine). This MOF/dye composite ZJU‐128⊃SP exhibits a blue emission from the ligand of ZJU‐128 at 447 nm and a red emission around 650 nm from spiropyran. Utilizing the photoisomerization of spiropyran from ring‐closed to ring‐open form under UV‐light irradiation,…
