A dual-functional 3D coordination polymer as a luminescent sensor for acetone in an aqueous medium and detecting the temperature

A novel coordination polymer, {[Cd-4(CcbP)(3)(dpe)(4)center dot 4H(2)O]center dot(ClO4)(5)center dot 4H(2)O} (CP 1) (Ccbp = 3-carboxy-1-(3-carboxybenzyl)pyridin-1-ium, dpe = 1,2-di(pyridin-4-yl)ethane), was synthesized under hydrothermal conditions by a zwitterionic organic ligand and dipyridine ligand, and was fully characterized. This CP 1 with a pyridine cation basic skeleton can be used as the first potential dual-function luminescence sensing material for the selective, sensitive and recyclable sensing of acetone molecules in aqueous phase and for the quantitative detection of ultra-low temperatures of 10 to 70 K.
