Phosphorescent Chemosensor Based on Iridium(III) Complex for the Selective Detection of Cu(II) Ion in Aqueous Acetonitrile

摘要

Cu(II) ion has two sides. In one side, Cu(II) ion is an important cofactor in nearly 20 metalloenzymes and an essential micronutrient for all living systems.But, in other side, Cu(II) ion is one of significant metal pollutants and toxic to living cells if present in slightly high concentrations, causing neurodegenerative diseases such as Menkes and Wilson's disease. In this instance, the selective detection of Cu(II) ion in environment and in living systems is very important. Consequently, various fluorescent chemosensors for the highly sensitive and selective detection of Cu(II) ion have been developed.
