Fluorescence　spectroscopic　properties　of　p-N,N-dimethylaminobenzonitrile　(DMABN)　in　various　kinds　of　surfactant　micellar　solutions　were　investigated.　The　results　showed　that　the　characteristics　of　the　palisade　layers　of　different　surfactant　micelles　affected　the　twisted　intramolecular　charge　transfer　(TICT)　properties　of　DMABN.　In　the　ionic　micellar　solution,　the　electric　field　of　the　charged　head-groups　in　the　palisade　layer　was　found　to　be　a　main　affecting　factor　that　promoting　the　formation　of　TICT　state.　The　larger　of　the　counterion　dissociation　degree,　the　stronger　of　Ia/Ib　in　the　micellar　solution.　In　the　nonionic　micellar　solution,　the　effect　of　hydrogen　bonding　became　distinct　due　to　a　large　amount　of　water　wrapped　in　the　shell　of　the　poly(ethylene　oxide)　(PEO)　chains.　Besides,　the　terminal　hydroxyl　groups　of　the　short　PEO　chains　were　also　able　to　hydrogen-bond　with　DMABN.　In　the　view　of　photo-physics　of　DMABN,　the　anionic　micelles　with　large　dissociation　degree　of　the　counterions　were　suitable　to　as　DMABN　dispersed　carriers　for　their　TICT　properties,　for　example,　SDS　or　SDSO.　©　Editorial　office　of　Acta　Physico-Chimica　Sinica.
