Abstract
Effect of beta-cyclodextrin (beta-CD) on micellization of cetyltrimeth ylammonium bromide (CTAB) in aqueous solution was investigated by twis ted intramolecular charge transfer (TICT) dual fluorescence of sodium p-dimethylaminobenzoate (SDMAB). It was shown that beta-CD induces the micellization of CTAB and the aggregation of CTAB below CMC as well. A reduced charge density at CTAB micelle interface in the presence of beta-CD, due to the incorporation of 1:1 CTAB-beta-CD inclusion comple x in micelle, was concluded to be the reason for beta-CD induced micel lization of CTAB.
