  Luminescent heptadentate Tb3+ complex with pendant aza-15-crown-5 showing recognition of lactate and salicylate in aqueous solution

  摘要：

  The coordinatedly unsaturated neutral complex TbL1 that possesses two labile metal-bound water Molecules provides linear response to lactate in the range of 0-3.0 mM at the simulated extracellular background with the variations of Tb luminescence lifetime as output: the maximal amplification of the luminescence intensity of TbL1 reaches a factor of 135 upon titration with aromatic antenna salicylate in the physiological pH window.

  [Graphics]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 lanthanicle luminescent lifetimes in aqueous solution.
