Solution interactions and solid-matrix interactions in beta-cyclodextrin solid-matrix luminescence

A variety of liquid chromatographic, solution fluorescence, and extraction data were obtained in an attempt to correlate solution interactions with solid-matrix interactions for solute-beta-cyclodextrin complexes. From the chromatographic data, dissociation constants were calculated for the complexes. Fluorescence spectral characteristics were obtained for sodium chloride, glucose, and beta-cyclodextrin solutions of several solutes. In addition, extraction experiments were performed in an attempt to remove the solutes from the beta-cyclodextrin solid matrix. Generally, the results revealed that there were no simple correlations between the solution data and solid-matrix luminescence data. However, the extraction results yielded important information related to the solute interactions in the solid matrix.
