n this contribution we show the effect of the surfactant polar head and the external solvent on the incorporationof different cyclodextrins (CDs) {α-CD, β-CD, γ-CD, decenylsuccinyl-β-CD (Mod-β-CD), and hydroxypropyl-β-CD (hp-β-CD)} in different reverse micelles (RMs) {benzene/sodium 1,4-bis(2-ethylhexyl) sulfosuccinate(AOT)/water, and benzene/benzyl-n-hexadecyldimethylammonium chloride (BHDC)/water} and compare them with previous results obtained in nheptane/AOT/water RMs. To investigate the different systems, we have used UV−vis spectrophotometry, induced circulardichroism spectroscopy (ICD), and the achiral molecular probe methyl orange (MO). The results show dramatic differenceschanging the external solvent and the surfactant, which are explained by considering the differences in the RMs interfacecomposition, the water−surfactant interaction, and the CDs? location in the different media investigated. None of the CDs wereincorporated in
