Ultrathin MOF nanosheets and their mixed-matrix membranes for ammonia and aliphatic amine sensing in water

Ultrathin Ni- btc MOF NS showed “turn-on” fluorescence in presence of NH 3 and aliphatic amines in water. Different dipole-dipole interactions between MOF NS and analytes, resulted in different fluorescence behaviour in order NH 3 > MA > DIPA > TEA.
