Abstract
采用丁二酮室温光猝灭法研究了胶束介质中丁二酮的增溶位点,通过研究4种不同荷电和不同亲水亲脂性的光猝灭剂以及盐效应等对STErn-VOlMEr常数的影响,表明了二酮在SdS、CTAb的胶束中是增溶在胶团的栏栅并靠近离子头基一侧和头基/水界面附近,而在CTAb胶束中更加趋向于胶团外部头基附近.
 
The solubilization site of the triplet energy acceptor biacetyl in normal micelles isstudied by quenched RTP.Ethyl iodide, butyl bromide were used as hydrophobic quenchers.Potassium bromide, copper chloride were the hydrophilic quenchers.The results indicatethat biacetyl is located in the head group-water interFace and likely to be lined up along thealkyl chains of the surFactant's aggregates but its carbonyl group is close to the head group ofsurFactant.So, iF donor is located in the head group-water interFace where biacetyl issolubilitized, enhanced energy transFer is observed.
