Abstract
The static and dynamical properties of nonionic micelles (Triton X-100, Igepal CO-630 and Brij-35) in aqueous solution have been investigated by pulsed 1H, 13C NMR relaxation, fluorescence probing and pulse radiolysis techniques. Chemical shifts and spin lattice relaxation times presented for the various resolved resonances in the proton and proton-decoupled 13C NMR spectra provide detailed information on the nature and segmental mobility of hydrocarbon chains in micellar core and that of ethylene oxide units in the palisade layer. The permeability of these nonionic micelles with respect to various species (ionic and nonionic) has been investigated by examining the dynamics of quenching of fluorescence emitted by “external” probe such as pyrene and “built in” phenoxyl unit. The basic photophysical features such as UV absorption, fluorescence lifetime and quantum yields for phenoxyl chromophore are also reported and these are used to gain information on the environment around these probes. Efficient excitation singlet energy transfer between phenoxyl unit and pyrene (solubilized in micellar core) has been observed.
