A Study of the Interaction of Methyl beta-CD with Cetyltrimethylammonium Bromide in Aqueous Solution

The interaction of methyl beta-CD with cetyltrimethylammonium bromide in aqueous solution was investigated by twisted intramolecular charge transfer(TICT) dual fluorescence of sodium diethylaminobenzoate. It was shown that an 1:1 CTAB/methyl beta-CD inclusion complex was formed in CTAB and methyl beta-CD mixed aqueous solution, and this inclusion complex formed aggregates incorporated by CTAB. Electric conductivity measurements provided further support for this conclusion.
