Inorganic-Organic　hybrid　perovskite-like　materials　have　potential　application　in　photodetection,　sensor　and　solar　cells　etc.　However,　these　materials　still　face　the　challenge　of　poor　stability.　A　new　inorganic-organic　hybrid　material　was　synthesized　by　solvothermal　method　using　H2DAB　as　the　template　and　counter　cation.　The　structure　is　composed　of　one-dimensional　(1D)　inorganic　perovskite-like　chain,　[(Me3)DAB(Me3)]2+　(DAB　=　benzidine)　dications　and　water　molecules.　This　compound　exhibits　good　stability　to　water　and　organic　solvents,　and　shows　typical　semiconductor　behavior.　Interestingly,　the　compound　also　shows　great　potential　for　humidity　sensing,　including　linear　sensitivity　(10-100%),　high　response　(5　orders　of　magnitude　of　current　change),　and　fast　recovery　time.
