Cyclodextrin-quinone inclusion compounds

THE CYCLODEXTRIN-QUINONE INCLUSION COMPOUNDS IN AN AQUEOUS SOLUTION AT 77 K, I. 9,10-ANTHRAQUINONE SULFONATES AND 1,4-NAPHTHOQUINONES... 

Heretofore, few studies on the cyclodextrin-quinone inclusion compounds have been reported [1,2]. Previously, we studied the n7r phosphorescence spectra of various p- and o-quinones in organic solvents at 77 K [3], and recently those of 9,10-anthraquinone (AQ) sulfonates in an aqueous solution at 77 K [4]. In this work, the complex formation between CD and AQ sulfonates and 1,4-naphthoquinones in an aqueous solution at 77 K was investigated using the nTr phosphorescence spectra of the quinones.
