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.

luminescence lifetime of TbL2 with a pendant 15-crown-5 increased by 65% to 2.95 ms with an [Na+] concentration of 0.13 M in aqueous solution; the maximum amplification of the luminescence intensity of TbL1 containing aza-15-crown-5 reached a factor of 47 upon addition of the aromatic antenna p-chlorobenzoate 1.
