Lanthanide-containing reversed micelles: A structural and luminescence study

Abstract:

Lanthanide surfactants of the type Ln(AOT)3 have been prepared and characterized, where Ln = Tb, Eu, Nd, and AOT is bis(2-ethylhexyl) sulfosuccinate. Small-angle neutron scattering experiments indicate that spherical reverse micelles form in cyclohexane. The luminescence lifetimes of lanthanide ions held inside these aggregates were found to depend on the molar ratio w = [water]/[AOT-]. This behavior is consistent with changes in the Ln3+ solvation: in "dry" micelles the ions are complexed by...
