Interactions of compounds adsorbed on an 80%. cap alpha. -cyclodextrin-sodium chloride mixture investigated by diffuse
The interactions of ..cap alpha..-cyclodextrin-analyte responsible for the luminescence phenomenon observed from compounds adsorbed on an 80% ..cap alpha..-cyclodextrin-sodium chloride mixture were compared with the interactions of the prepared solid-phase ..cap alpha..-cyclodextrin complexes of the compounds. Diffuse reflectance spectrometry and luminescence spectrometry were used in the study. The luminescence data with benzo(f)quinoline (B(f)Q) indicated that the nitrogen-containing ring of B(f)Q was inside the ..cap alpha..-cyclodextrin cavity in the 80% mixture, while in the prepared inclusion compound the pyridinic nitrogen was outside the ..cap alpha..-cyclodextrin cavity. The diffuse reflectance spectra of several compounds adsorbed on an 80% ..cap alpha..-cyclodextrin-sodium chloride mixture and on NaCl were compared. Some of the compounds showed a red shift in their reflectance band maximum, and other compounds showed well-resolved vibronic bands on the 80% ..cap alpha..-cyclodextrin mixture. In addition, the amount of unbound analyte on the ..cap alpha..-cyclodextrin-sodium chloride matrix was determined.
