  • To enhance the binding ability of β-cyclodextrin with naphthalene derivatives,a hydrophobic group to the rim of β-cyclodextrin was added and the new β-cyclodextrin compound—mono-6-p-nitrobenzoyl-β-cyclodextrin was synthesized. Its binding ability for 1: 1 inclusion complexation with 1-naphthoic acid was evaluated in the KCl/HCl buffer solution(pH=1.5,0.1 mol/dm3)at 15℃ by the spectrofluormetric titration. The results obtained indicated that mono-6-p-nitrobenzoyl-β-cyclodextrin could strongly include 1-naphthoic acid in aqueous solution;the modification dramatically enhanced the original binding ability of native β-cyclodextrin by a factor 9. The binding constants of mono-6-p-nitrobenzoyl-β-cyclodextrin and other naphthalenes such as 1-methoxynaphthalene,2-methoxynaphthalene,1-N,N-dimethylaminonaphthalene and 1-N,N-dimethylaminonaphthalene were obtained from the time-resolved fluorescence. The high binging ability of naphthalenes with NBCD make it is possible to assemble stable host-guest complexes.

Abstract: To enhance the binding ability of β-cyclodextrin with naphthalene derivatives,a hydrophobic group to the rim of β-cyclodextrin was added and the new β-cyclodextrin compound—mono-6-p-nitrobenzoyl-β-cyclodextrin was synthesized. Its binding ability for 1: 1 inclusion complexation with 1-naphthoic acid was evaluated in the KCl/HCl buffer solution(pH=1.5,0.1 mol/dm3)at 15℃ by the spectrofluormetric titration. The results obtained indicated that mono-6-p-nitrobenzoyl-β-cyclodextrin could strongly include 1-naphthoic acid in aqueous solution;the modification dramatically enhanced the original binding ability of native β-cyclodextrin by a factor 9. The binding constants of mono-6-p-nitrobenzoyl-β-cyclodextrin and other naphthalenes such as 1-methoxynaphthalene,2-methoxynaphthalene,1-N,N-dimethylaminonaphthalene and 1-N,N-dimethylaminonaphthalene were obtained from the time-resolved fluorescence. The high binging ability of naphthalenes with NBCD make it is possible to assemble stable host-guest complexes.
