Luminescent Tb3+ complex with pendant crown ether showing dual-component recognition of H+ and K+ at multiple pH windows.
[structure: see text] A lanthanide luminescent probe that was functionalized with quinoline-alkylated diaza-18-crown-6 showed dual-component recognition of concentrations of H+ and K+ at four independent pH ranges, including in the physiological pH window. Moreover, it exhibited pH- and [K+]-independent long-lived lanthanide luminescent lifetimes in aqueous solution.
