Spectroscopic determination of pressure-induced shifts in inclusion complexation equilibria
Evans, Christine E.
, p. 2136 - 2142 (1997)
The effect of modest hydrostatic pressure (c ranging from clearly pressure dependent (-14%) to pressure independent over 338 bar. Additional solvation perturbations are observed in the pressure dependence of the quantum efficiency for both complexes (-7.3% and -9.4%). Thus, pressure-induced perturbation in the fluorescence properties of the complex need not be accompanied by simultaneous changes in the complexation equilibrium. Finally, these pressure-induced changes in complexation selectivity are important for all measurements conducted under variable pressure conditions, including liquid chromatography and process monitoring.
Thermodynamic Study on the Effects of β-Cyclodextrin Inclusion with Anilinonaphthalenesulfonates

Thermodynamic parameters and stoichiometries for the binding of anilinonaphthalenesulfonates to β-cyclodextrin are obtained from steady-state fluorescence intensity and anisotropy measurements.Specifically, formation constant, enthalpy, and entropy values are obtained for complexes of β-cyclodextrin with eight different substrate molecules at five different temperatures and six different pH values, and their associated errors are given.We propose an explanation of the relative magnitudes of the values obtained with regard to the geometry of the substrate and the importance of the various noncovalent interactions responsible for the complexation.
