| 英文摘要 | A set of heterodouble-chained n-acyltaurate surfactants (abbreviated as m + np-t, where m and n were carbon numbers of alkyl chain; p was phenyl; t was taurate) were synthesized. the novel amphiphiles contained sodium taurine as hydrophilic moiety and two different hydrocarbon chains as hydrophobic moiety. one was a long alkyl chain, and the other had an aromatic residue. their surface properties were determined by wilhelmy-plate method, and micellization properties were investigated by fluorescence spectra of extrinsic probe and intrinsic probe. it was found that these surfactants showed some aberrant properties. it was difficult to obtain the equilibrium surface tension and critical micelle concentration (cmc) for the surfactants with two long chains. pyrene was solubilized in micelle at concentration above cmc, and the fluorescent intensity ratio of the first vibronic peak (373 nm) to the third vibronic peak (383 nm) of pyrene decreased gradually. the aggregation number n, characterized by quenching the phenoxyl residue with methyl viologen (mv2+) as the extrinsic quencher, gradually increased with increasing surfactant concentration. these indicated that more and more molecules packed in a micelle with increasing concentration. |
