摘要：

The interaction of the p-nitrophenol/p-nitrophenolate conjugate has been investigated with different 2-hydroxypropyl-beta-cyclodextrin hosts. The measured values for stability constants attain a maximum as a function of increasing average degree of substitution. The quotients of constants, characterizing the inclusion of p-nitrophenolate and p-nitrophenol, respectively, are decreased showing that the effect of London dispersion forces is greatly overshadowed by the hydroxypropylation.
