Luminescent Tb3+ Complex with Pendant Crown Ether Showing Dual-Component Recognition of H+ and K+ at Multiple pH Windows
摘要:
[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.

Potential magnetic resonance imaging (MRI) contrast agents that are functionalized with crown compounds have been synthesized, and show target-specificity to the kidney and liver, along with excellent water solubility, high MR intensity enhancement efficiency, long resident lifetime, low dosage requirement, low cytotoxicity and prolonged excretion rate.
