摘      要：A new bipyridine fused rhodamine-like chelating ligand and the corresponding transition metal complexes of platinum(Ⅱ)and iridi-um(Ⅲ)have been designed,synthesized and structurally characterized by X-ray *** photophysical properties and acid-or metal ion-promoted spirocarbon ring-opening properties have been *** platinum(Ⅱ)and iridium(Ⅲ)complexes show a drastic color change in solution with Hg^(2+) ions and emergency of an absorption band at around 450-600 nm,assignable to the absorption band of the ring-opened rhodamine-like *** platinum(Ⅱ)complex was suggested to undergo dissociation with Hg^(2+) ion,based on the corresponding absorption titration *** titration studies of iridium(Ⅲ)complexes were found to suffer from the quenching process,probably due to the presence of a lower-lying non-emissive excited state from the ring-opened form of ligand.
