* In this study, three kinds of Zn-based 0D OIMHs with different crystal structures and luminescent properties were constructed by controlling the crystallization solvent, and the emission control in the range of 540-652 nm was realized. Combined with structural analysis, temperature-dependent luminescence spectrum and theoretical calculation, the effects of crystal structure, electron-phonon coupling and excited state behavior on luminescence properties under the control of crystallization solvent are revealed. On this basis, the exchange, removal and reintroduction of lattice solvents are used to drive the structural transformation among the three crystal phases, accompanied by significant luminescence switching, which shows that solvents can not only regulate the formation of crystal phases, but also be used as external stimuli to dynamically adjust the structure and luminescence properties of materials. Based on the crystal phase transition and luminescence response of 5-DQL-ZnCl IPA to acetone vapor, it was encapsulated in PSTB hydrogel to construct IPA@PSTB sensing platform, and the visual quantitative detection of 1.0-5.0 ppm acetone was realized, with the detection limit of 0.79 ppm. Furthermore, the platform can be used in animal experiments, which can distinguish the acetone-related signals in IVC exhaust of rats with different metabolic States and dynamically track the changes of the signals during insulin treatment.
