详细

The complexation process of tolane and α-cyclodextrin in water, aqueous-ethanol solution and silicate hydrogel based on tetrakis(2 hydroxyethyl)orthosilicate was studied. The complex formation in solutions were confirmed by electron and 1H NMR spectroscopy, and the stability constant of the complex was determined using spectrofluorimetric titration (lgK1:1 = 1.5). The preservation of the inclusion complex during the preparation of the gel was confirmed by electron spectroscopy.
