摘要

摘要研究了甲苯与α-环糊精在水、乙醇水溶液和基于四（2-羟乙基）原硅酸盐的硅酸盐水凝胶中的络合过程。电子和 1H NMR 光谱证实了溶液中络合物的形成，并利用分光荧光滴定法测定了络合物的稳定常数（log K1 : 1 = 1.5）。电子能谱证实了在凝胶制备过程中包合复合物的保存情况。

Spectral Properties of Tolane and Its Supramolecular Complexes in Solution and Silicate Hydrogel

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 K_{1 : 1} = 1.5). The preservation of the inclusion complex during the preparation of the gel was confirmed by electron spectroscopy.
