Abstract

Abstract Three amphiphilic antimony(V)-phthalocyanines have been synthesized by treating [Sb(R4Pc)(OH)2]+ salts in concentrated H2SO4 and isolated as zwitter ions, [Sb(R4Pc)(SO4H)(SO4)], where R4Pc denotes tetra-substituted phthalocyaninate; R4Pc=pc (R=H), tbpc (R=tBu), and tObpc (R=OnBu). Their solubility (R=tbpc>pc >>tObpc in H2O (much improved by the presence of surfactant or alcohol) while tbpc>tObpc >>pc in CH2Cl2) 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.
