A series of single-chain amphiphiles containing Schiff base moiety(CnSchC4N+ , n=4, 7, 10, 12, 16) were synthesized. The self-assembly properties were investigated by 1H NMR spectra, DSC and EM for aqueous solutions of these samples. The aggregates, vesi-cles, were formed when n=7. The influence of additional group-O-is discussed.
