Luminescent sensory material for organic-halogen compounds, and methods and apparatus utilizing such

Abstract

A luminescent sensory material for the detection of the presence of organo-halogen compounds is described. This material is based on a platinum chromophore functionalized with pyridylacetylide ligands, as shown in Formulae I and II (refer to Patent file). These complexes exhibit positive luminescence upon exposure to the vapors of organ-halogen compounds like CH₂2Cl₂ or CHCl₃ with high selectivity over non-chlorinated common organic vapors. Direct relationships between vapor concentration and luminescence intensity are established using thin films prepared from these complexes.
