A novel antimony-phthalocyanine, [Sb(H₃tsppc)(OH)₂], where H₃tsppc denotes monodeprotonated tetrakis{(2′,6′- dimethyl-4′-sulfonic acid)phenoxyl}phthalocyaninate, has been synthesized through sulfonation of [Sb(tppc)(OH)₂]⁺ (tppc denotes tetrakis{(2′,6′-dimethyl)phenoxyl}phthalocyaninate) in concentrated sulfuric acid. This compound is highly soluble in water (ca. 4 × 10 ^{- 2} M) without surfactant or alcohol. Moreover, it has been found free from aggregation in water up to almost 10^{- 4} M, unlike its copper and metal-free analogues, and show an intense optical absorption and emission band in optical therapeutical window (700-800 nm). The axial hydroxyl groups play a crucial role in disaggregation of the antimony derivative in water.
