Abstract
Novel 1,1'-binaphthyl substituted calixresorcinols (1 and 2) were synthesiz ed. Macrocycles 1 and 2 form water-soluble complexes with methyl red 3, whi ch are, in turn, able to bind saccharides by a competition process in aqueo us media and which exhibit color transitions during titration. Preferential binding of oligosaccharides compared to monosaccharides was found. The ass ociation constants of effectively bound oligosaccharides in aqueous media V aried around 10(3) M-1.
