L. Fabbrizzi et al., MOLECULAR RECOGNITION OF THE IMIDAZOLE RESIDUE BY A DICOPPER(II) COMPLEX WITH A BISDIEN MACROCYCLE BEARING 2 PENDANT ARMS, Journal of the Chemical Society, Chemical Communications, (23), 1995, pp. 2439-2440
The dicopper(II) macrocyclic complex 4 tightly binds the imidazolate i
on in aqueous solution at pH 9 and recognises molecules containing an
imidazole fragment, e.g. L-histidine, in the presence of any other ami
no acid.
