摘要：

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 = Bu-t), and tObpc (R = (OBu)-Bu-n). 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. (C) 2012 Elsevier Inc. All rights reserved.
