Amphiphilic alkyl (dodecyl and hexadecyl)-2-hydroxy-3-chloropropyl phosphates (C 12 - and C 16 -AHCP) were synthesized, and then alkyl glycidyl phosphates (C 12 - and C 16 -AGP) were quantitatively obtained by the tre...Amphiphilic alkyl (dodecyl and hexadecyl)-2-hydroxy-3-chloropropyl phosphates (C 12 - and C 16 -AHCP) were synthesized, and then alkyl glycidyl phosphates (C 12 - and C 16 -AGP) were quantitatively obtained by the treatment of AHCP with NaOH in order to prepare a novel vesicle which has reactive and polymerizable epoxy group on its membrane surface. The bilayer vesicles were formed by ultrasonication of aqueous dispersion of C 16 -AHCP or C 16 -AGP, but the vesicles composed of C 12 -AHCP and C 12 -AGP were not obtained by the same treatment. Both of C 16 -AHCP and C 16 -AGP bilayer vesicles are only stable at pH 5—10 or the ionic strength below 0.15. The gel-filtration chromatography and the UV-Vis absorption spectroscopic studies on Co(Ⅱ) tetrakis(propyloxycarbonyl)phthalocyanine as a lipophilic probe indicated that the phthalocyanine was effectively incorporated into the C 16 -AHCP bilayer membranes and predominantly present in a monomeric state in the membranes, which is much different from its leading diameric state in SDS micelle and ethanol.展开更多
