Fluorometric sensing of alkali metal and alkaline earth metal cations by novel photosensitive monoazacryptand derivatives in aqueous micellar solutions
selective Ba2+ detection among alkalimetal and alkaline earth metalcations. With respect to the selective fluorescent detection of important metalcations (Na+, K+, Mg2+, Ca2+) relevant to living organisms, was found to detect K+ with high selectivity in aqueous micellar solutions of polyoxyethylene(20) sorbitan monostearate (Tween-60). The selectivity for metalcations was mainly dependent on the goodness
