Synthesis and Characterization of Novel Multifunctional Host Compounds. 4. Cyclodextrin Derivatives Bearing Chromophores

Abstract Nine novel cyclodextrin derivatives were synthesized and characterized by 1H-NMR, 13C-NMR, FT-IR, TLC, and elemental analysis. A solvent mixture consisting of acctone and water(5:1) was found effective for separation and purification of modified cyclodextrins bearing one or two hydrophobic moieties. The purification method of β-CD—6—OTs was improved.
