Six new cyanine dye functionalised β-cyclodextrins were designed and synthesized to improve the drawback of the inadequate chromophore in β-cyclodextrin and to be suitable for the study of supramolecular interactions directly by visible spectroscopy. The dye structures were confirmed by 1H NMR, IR, UV-Vis and HRMS. The UV-Vis spectra of the new cyanine dyes in different solvents were investigated. The inclusion behaviour of a quinocyanine derived β-cyclodextrin dye which was used as the supramolecular host with 1-adamantanol or vitamin B6 was investigated. The results indicated that the stoichiometry for the inclusion complex of the quinocyanine derived β-cyclodextrin dye and both 1-adamantanol and vitamin B6 was 1:1, and their inclusion constants were 9.39 × 104 L/mol and 6.14 × 102 L/mol, respectively. The quinocyanine derived β-cyclodextrin dye was also used as the supramolecular host for the analysis of vitamin B6 in tablets with satisfactory results.
