摘要
Atom transfer radical polymerization of protected 2 hydroxyethyl acrylate (HEA\|TMS) was conducted to prepare well\|defined bromo\|terminated macroinitiators,which were further allowed to react with large excess amount of C 60 under ATRP condition.A well defined hammer shaped C 60 PHEA was then obtained by hydrolysis of C 60 PHEA TMS under mild conditions.A TEM observation of the association behavior of these well defined hammer like C 60 PHEA macromolecules showed that they assemble into spherical vesicles in water.Their characteristic inner water phase was further confirmed by fluorescence probe method.Also,it was found that the size of vesicles decreased as the increase of molecular weight of PHEA.
Atom transfer radical polymerization of protected 2-hydroxyethyl acrylate ( IIEA-TMS) was conducted to prepare well-defined bromo-terminated macroinitiators, which were further allowed to react with large excess amount of C-60 under ATRP condition. A well-defined hammer-shaped C-60-PHEA was then obtained by hydrolysis of C-60-PREA-TMS under mild conditions. A TEM observation of the association behavior of these well-defined hammer-like C-60-PHEA macromolecules showed that they assemble into spherical vesicles in water. Their characteristic inner water phase was further confirmed by fluorescence probe method. Also, it was found that the size of vesicles decreased as the increase of molecular weight of PHEA.
