Abstract：

Stimulus-responsive　inorganic-organic　hybrid　metal　halides　(IOMHs)　have　shown　great　potential　in　applications　such　as　sensing　and　anti-counterfeiting.　IOMHs　can　undergo　a　variety　of　structural　changes　when　triggered　by　humidity;　however,　relevant　reports　of　structural　dimensionality　change　from　zero　dimension　(0D)　to　one　dimension　(1D)　are　rare.　This　study　investigates　the　synthesis,　structure,　and　properties　of　two　antimony-based　IOMHs,　namely　0D-(Mp)3SbCl6MeCN　and　1D-(Mp)2SbCl5　(Mp　=　protonated　morpholine;　MeCN　=　acetonitrile).　Photophysical　characterizations　show　that　(Mp)3SbCl6MeCN,　when　being　excited　at　375　nm,　exhibits　typical　self-trapped　exciton　triplet　state　broad-band　emission,　with　a　peak　at　620　nm　and　a　quantum　yield　as　high　as　75.06%.　Under　humid　conditions,　the　0D　structure　of　(Mp)3SbCl6MeCN　undergoes　a　phase　transition,　leading　to　the　1D　structure　of　(Mp)2SbCl5.　This　transition　is　accompanied　by　fluorescence　quenching.　X-ray　powder　diffraction,　Raman　spectroscopy,　and　thermogravimetric　analysis　confirm　the　phase　transition　process　and　its　reversibility.　Based　on　the　high　contrast　of　fluorescence　before　and　after　phase　transition,　(Mp)3SbCl6MeCN　is　demonstrated　as　an　ideal　material　for　fluorescence　water　sensing,　capable　of　detecting　trace　amounts　of　water　in　tetrahydrofuran　with　a　detection　limit　of　0.2%　v/v.
