Microemulsions composed of metal complex surfactants, bis(octylethylenediamine (= OE)) Zn(II), Cd(II), and Pd(II) chlorides, in water/chloroform and water/benzene systems

摘要

Bis(N-octy lethy lenediamine (= OE)) zinc(II), cadmium(II), and palladium(II) complexes (Zn(OE)_2Cl_2, Cd(OE)_2Cl_2, and Pd(OE)_2Cl_2) wee prepared, and the characteristic structures of the aggregates wee investigated in such mixed solvents as water/chloroform, water/benzene, and water/methanol using ~1H NMR pulsed-gradient spin echo (PGSE) and TEM (transmission electron microscopy) methods. These complexes form reverse micelles or w/o microemulsions in water/chloroform or water/benzene depending on the hydrophilicity of the headgroup.
