Abstract
Benzyl-2-pyridylketone-2-pyridylhydrazone and β-cyclodextrin form a 1 : 1 adduct in water with a standard free energy change, ΔG o, in the region of 14.2 kJ mol−1 at 25°C, and an association constant of 275 M−1 in the pH range 5–7. These values have been obtained by using the fluorimetric spectral changes associated with the inclusion process.
