Abstract

Polymeric vesicular aggregates with spherical and tubular shapes were formed from the self‐assembly of a porphyrin‐centered amphiphilic star poly(oxazoline) [poly(phenyloxazoline)‐block‐poly(methyloxazoline)] in an DMF/water mixture containing excess DMF. The aggregates were evaluated by means of UV‐Vis, fluorescent, ^1^H NMR spectroscopies, and optical microscopy. The driving force to induce the vesicular aggregates is the interactions between poly(phenyloxazoline) segments which were insoluble in DMF rich aqueous medium.

Polymeric vesicular aggregates with spherical and tubular shapes were formed from the self‐assembly of a porphyrin‐centered amphiphilic star poly(oxazoline) [poly(phenyloxazoline)‐block‐poly(methyloxazoline)] in an DMF/water mixture.
