At present, using cyclodextrins or cyclodextrin derivatives with suitable internal annular dimension to embed C60 so as to form inclusion complexes has been one of the main ways to improve C60＇s water-solubility. In three kinds of cyclodextrins (α-, β-, γ-CD), only γ-CD has cavity large enough to include C60 whereas α-, and β-CD have not. In the case of DMβCD, the “out-stretching” methyl groups enlarge the cavity so that it can include C60. Starting from the same thought, we use epichlorohydrin crosslinked water-soluble
