Abstract

A water-soluble complex of C₇₀ with δ-cyclodextrin (δ-CD) which was isolated and purified from cyclodextrin powder in our laboratory was investigated. The complex was characterized by its UV-VIS spectrum, which had higher aqueous solubility than that of the complex between C₇₀ and γ-cyclodextrin (γ-CD). the aqueous solution had a red-brown color and resembled the color of C₇₀ in toluence solution.
