In this work, a fluorescence chemosensor based on organic-inorganic hybrid CH3NH3PbBr3 perovskite nanoparticles has been investigated for the detection of volatile organic compounds (VOCs), aliphatic amines (monoethylamine, diethylamine, and trimethylamine). Perovskite films showed fast (< 1 s), highly discernible (89%), and reversible/irreversible fluorescence quenching behavior in response to the amine vapor exposure. Detection mechanism was confirmed by crystalline structural analysis based on X-ray diffraction (XRD) measurements and quantum chemical calculations, which proved that fluorescence quenching originates from the structural conversion from perovskite to its components by reversible or irreversible hydrogen bonding interaction between perovskite and aliphatic amines. This study suggests a simple but very effective strategy for naked eye-based fluorescence sensing of the colorless and harmful aliphatic amine vapors. (C) 2017 Elsevier Ltd. All rights reserved.
