Host/Guest Complexes Containing Cyclodextrins and Dyes

By: Daniel Jenkinson Abstract It was determined that the wavelength of fluorescence of PRODAN is lengthened in a more polar solvent, or when complexed in a cyclodextrin, since the energy difference between the ground and excited state is lowered due to stabilisation from polar groups. When using β-cyclodextrin, a 1:1 stoichiometry is adopted, but when using γ-cyclodextrin, a 2:1 ratio of PRODAN: cyclodextrin is preferred. The equilibrium constant for bonding with β-cyclodextrin was 8500 M-1, and the product of the […]
