摘要：

A new fluorescence macrocyclic receptor based on the Zn(II) complex of a C-2-terpyridine and a crown ether has been developed for molecular recognition of zwitterionic amino acids in water/DMF solution with remarkable selectivity towards L-aspartate (K = 4.5 x 10(4) M-1) and L-CyStei ne (K = 2.5 x 10(4) M-1).
