Stable porphyrin vesicles formed in non-aqueous media and dried to produce hollow shells

Stable vesicles of an amphiphilic manganese complex of 5,10,15,20-tetrakis-4-oxy(2-stearic acid) phenylporphyrin [Mn(III)TPP(COOH)] were formed in non-aqueous solution (CHCl3 + CH3OH, 4 : 1 v/v); the vesicles can be dried to produce hollow shells.
