Issue Date: | 14-Feb-2006 | Source: | US Patent 6,998,271 B2. Washington, DC: US Patent and Trademark Office, 2006. | 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 below. These complexes exhibit positive luminescence upon exposure to the vapors of organ-halogen compounds like CH.sub.2Cl.sub.2 or CHCl.sub.3 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. ##STR00001## | Rights: | Assignee: The Hong Kong Polytechnic Univeristy Assignee: The University of Hong Kong. |
