The synthesis of triazolephthalocyanines bearing crown ether and aza-crown ether substituents is described. Different substituents have been introduced on the nitrogen atom of the aza-crown moiety to improve the solubility and the intrinsic amphiphilic character of these macrocycles. The crowned tri
