Abstract
New amphiphilic cyclodextrins are synthesized by selective modification. Two synthetic strategies are investigated. Per-(6-thio-2,3-trimethylsilyl)cyclodextrins can only be obtain by synthesizing first the per-6-thio-cyclodextrin and then silylating the remaining hydroxy functions. Characterizations of the products were achieved by ESI-MS and intramolecular coupling between thiol functions was evidenced. These new compounds are shown to be amphiphilic, and form stable Langmuir–Blodgett films that can be transferred on the upstroke and the downstroke of a substrate with a transfer ratio close to unity.
