An ABX3 organic-inorganic perovskite-type material with the formula (C5N2H9)CdCl3: Application for detection of volatile organic solvent molecules

ABX(3) organic-inorganic hybrid perovskite materials, particularly CH3NH3PbI3, have been widely investigated in recent years. However, organic-inorganic hybrid perovskite materials containing N-heterocyclic are still rarely reported. Herein, we discover a new material, namely, (C5N2H9)CdCl3 (1) by slow evaporation method. The structure of compound 1 was determinated by single crystal X-ray diffraction patterns, and it exhibits 1D chain based edge-sharing CdCl5 tetragonal pyramid. FT-IR and powder X-ray diffraction patterns (PXRD) were performed to confirm the purity of the prepared crystals. The optical diffuse-reflectance spectra indicate that (C5N2H9)CdCl3 is a wide band-gap semiconductor with optical band gap of 3.50 eV. Thermogravimetric analysis (TGA) indicates that 1 is thermally stable up to around 226 degrees C. In addition, based on the measurement of luminescence properties of 1 at room temperature, the emission spectra of 1 shows a blue fluorescent emission peak at 420 nm (lambda(ex) = 315 nm). And the fluorescence quenching of 1 by acetonitrile has been studied at room temperature. (C) 2017 Elsevier Ltd. All rights reserved.
