contribution at pH values above the pKa of its phenylboronic acid moiety. The interaction of the Gd3+ complexes of L1 and L2 with each of several saccharides was investigated by means of a competitive fluorescent assay. The results show that both complexes recognize sialicacid with good selectivity in the presence of other sugars. The adduct formed by GdL2 with sialicacid has the higher conditional formation
