Abstract: Four amphiphilic bifunctionalized β-cyclodextrin derivatives with low degree of substitution(DS) were conveniently synthesized via the reaction of 2-O-(2-hydroxypropyl)-β-cyclodextrin with Lauryl glycidol ether, tetradecyl glycidol ether, hexadecyl glycidol ether and octadecyl glycidol ether in pyridine, respectively. The four amphiphilic β-CD derivatives(DS 1.87, 1.95, 2.14 and 1.80, respectively) could self-assemble in water to form stable nanospheres with improved dispersion degree and uniformity up to 2~3 weeks.

Key words: amphiphilic, O-(hydroxypropyl)-&, beta, -cyclodextrin, glycidol ether, nanospheres
