Three amphiphilic antimony(V)-phthalocyanines have been synthesized by treating [Sb(R(4)Pc)(OH)(2)](+) salts in concentrated H(2)SO(4) and isolated as zwitter ions, [Sb(R(4)Pc)(SO(4)H)(SO(4))], where R(4)Pc denotes tetra-substituted phthalocyaninate; R(4)Pc=pc (R=H), tbpc (R=(t)Bu), and tObpc (R=O(n)Bu). Their solubility (R=tbpc>pc >tObpc in H(2)O (much improved by the presence of surfactant or alcohol) while tbpc>tObpc >pc in CH(2)Cl(2)) and aggregation behaviors are highly sensitive to the nature of the peripheral substituents. The pc and tbpc derivatives form well-behaved J-aggregates in aqueous media in the presence of surfactant or alcohol.
