Photosalient effect and reversible photochromic photoluminescence driven by cascade [2 + 2] cycloaddition reaction and water adsorption in a 0D hybrid metal halide.

ABSTRACT: The ionic structure of hybrid metal halides (HMHs) is conducive to the integration of the photoactivity of organic components and mechanical properties of inorganic components. Therefore, HMHs can function as a suitable platform to advance photomechanical performance due to their great structural designability and wide compositional diversity. Herein, a notable photosalient effect was observed in 0D ionic (LH)₂InCl₅ (1, L = 4-styrylpyridine). Upon irradiation with 450 nm light, 1 undergoes a rare single-crystal-to-single-crystal transformation to (L₂H₂)[In(H₂O)Cl₅] (1a), along with distinct photochromic photoluminescence and various photomechanical responses, driven by the cascade photoinduced [2 + 2] cycloaddition of LH
