Abstract
Abstract Fluorescence probe and nuclear magnetic resonance (NMR) methods were employed to investigate the micellation of prepared crown ether surfactants, eg decyl 15- crown-5 and decyl 18-crown-6. Pyrene was employed as the fluorescence probe to evaluate the critical micellar concentration (CMC) of these surfactants in aqueous solutions while spin lattice relaxation times (T 1) and chemical shifts of H-1 NMR were applied in non-aqueous ...
