Abstract
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 (log K1 : 1 = 1.5). The preservation of the inclusion complex during the preparation of the gel was confirmed by electron spectroscopy.
