A charged iridophosphor for time-resolved luminescent CO2 gas identification

Abstract

A phosphorescent CO2 gas probe based on an iridium(III) complex with 2-phenylimidazo-[4,5-f][1,10]phenanthroline ligand has been developed. Its phosphorescence is quenched by the addition of CH3COO. The quenched phosphorescence can be recovered by bubbling CO2 into the detecting solution. This phosphorescent CO2 probe exhibits higher photostability and reduced photobleaching than some of the reported organic fluorescent probes. A time-resolved photoluminescence experiment was performed for CO2 gas detection, which could effectively remove the background fluorescence and improve the sensitivity and signal-to-noise ratio of the sensor in complicated media.
