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 studied. 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 operating with complexes in the silica gel matrix were 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, 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.

硅酸盐水凝胶基质中β-环糊精-苯乙烯超分子复合物的稳定性
摘要 为了将β-环糊精-苯乙烯复合物用作荧光受体中心,研究人员对其在水溶性硅酸盐凝胶固相中的稳定性进行了研究。为此,研究人员开发了一种获得高含量超分子络合物硅酸盐基质的技术,并对所得材料的温度稳定性进行了研究。确定了硅胶基质中复合物的最佳操作条件。利用荧光光谱法对液相和固相中络合物的荧光光谱进行了比较研究。研究结果确定了超分子复合物在硅酸盐水凝胶基质中的主要行为模式,并总结出基质结构对其稳定性的影响。
