Abstract
A macrocyclic glycocluster host molecule (Glu-Host) which has a strong polar sugar-cluster part interact with many dyes via hydrogen-bonding in a polar solvent. The interactions are detected by UV-VIS spectroscopic change due to host-guest complexation. Especially, UV-VIS spectra of all triphenylmethane type dyes such as Brilliant Blue G are changed. Bingding constants of some dyes are able to calculate and these host-guest interactions are very strong because the binding constants calculated are large value.
