LUMINESCENT TRANSITION METAL-LIGAND COMPLEX AND SENSOR, PROBE, SYSTEM AND METHOD BASED THEREON FOR DETECTING POLAR SOLVENTS

摘要

The present invention relates to a transition metal-ligand complex that shows changes in its luminescence lifetime characteristic and/or luminescence intensity as a function of the polarity and/or hydrogen bonding properties of its environment, and a sensor, probe, system and method based on the complex for detecting the presence, amount or concentration of a polar solvent in a medium.
