Metallohelical triangle cryptate MC-1 was assembled by Zn2+ and two tridentate (N2O) ligand H2L1 [N-(3,5-bis((E)-2-(pyridin-2-ylmethylene)hydrazinecarbonyl)phenyl)-5-(dimethylamino)napthalene-1-sulfonamide] with dansyl sulfonamide group and hydrogen bond site. UV-vis and fluorescence spectra, ESI-MS and 1H NMR of MC-1 were measured for recognition of glucosamine and glucose. It was found that MC-1 exhibited good response of UV-vis and fluorescene toward glucosamine, but no response for glucose. Moreover, 1:1 stoichiometric host-guest complexation of MC-1 for glucosamine was confirmed by the titration profile and electrospray ionization mass spectrometry (ESI-MS) spectrum, with an association constant (lgKass) being calculated as 7.23±0.03.

Key words: cryptate, glucosamine, dansyl sulfonamide, recognition
