Abstract:

The interaction of methyl β-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 β-CD inclusion complex was formed in CTAB and methyl β-CD mixed aqueous solution ,and this inclusion complex formed aggregates incorporated by CTAB. Electric conductivity measurements provided further support for this conclusion.
