Abstract
In order to use the β-cyclodextrin-pyrene complex as a fluorescent receptor center, its stability in the solid phase of a water-soluble silicate gel was investigated. For this purpose, a technique for obtaining a silicate matrix with a high content of supramolecular complexes was developed and the temperature stability of the resulting material was investigated. Optimal conditions for working with complexes in the silica gel matrix have been identified. Comparative studies of the fluorescence spectra of complexes in liquid and solid phases were carried out by the method of fluorescence spectroscopy. As a result of the work done, it was possible to determine the main patterns of behavior of the supramolecular complex in the silicate hydrogel matrix and to conclude about the influence of the matrix structure on its stability.
