Abstract

A phosphorescent CO2gas 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 CO2into the detecting solution. This phosphorescent CO2probe exhibits higher photostability and reduced photobleaching than some of the reported organic fluorescent probes. A time-resolved photoluminescence experiment was performed for CO2gas detection, which could effectively remove the background fluorescence and improve the sensitivity and signal-to-noise ratio of the sensor in complicated media.
