Аннотация: <jats:title>Abstract</jats:title><jats:p>The development of lead-free perovskite photoelectric materials has been an extensive focus in the recent years. Herein, a novel one-dimensional (1D) lead-free CsMnCl<jats:sub>3</jats:sub>(H<jats:sub>2</jats:sub>O)<jats:sub>2</jats:sub> single crystal is reported with solvatochromic photolumПоказать полностьюinescence properties. Interestingly, after contact with N,N-dimethylacetamide (DMAC) or N,N-dimethylformamide (DMF), the crystal structure can transform from 1D CsMnCl<jats:sub>3</jats:sub>(H<jats:sub>2</jats:sub>O)<jats:sub>2</jats:sub> to 0D Cs<jats:sub>3</jats:sub>MnCl<jats:sub>5</jats:sub> and finally transform into 0D Cs<jats:sub>2</jats:sub>MnCl<jats:sub>4</jats:sub>(H<jats:sub>2</jats:sub>O)<jats:sub>2</jats:sub>. The solvent-induced crystal-to-crystal phase transformations are accompanied by loss and regaining of water of crystallization, leading to the change of the coordination number of Mn<jats:sup>2+</jats:sup>. Correspondingly, the luminescence changes from red to bright green and finally back to red emission. By fabricating a test-paper containing CsMnCl<jats:sub>3</jats:sub>(H<jats:sub>2</jats:sub>O)<jats:sub>2</jats:sub>, DMAC and DMF can be detected quickly with a response time of less than one minute. These results can expand potential applications for low-dimensional lead-free perovskites.</jats:p>
