Synthesis of Molybdenum 4,4′, 4", 4'"-Tetrasulfophthalocyanine and Its Fluorescence

Abstract

Abstract: A solid Phase synthetic method for Molybdenum 4,4′,4",4′"tetrasulfo-phthalocyanine and its fluorecsence spectra are given in detail. It was synthesised with triammonium 4-sulfophthalate,urea and Mo(V) hydroxide, boric acid and ammonium chloride were used as catalysts. Anal, calcd. for(C₈H₃N₂SO₃Na)₄MoO₂·4H₂O: C34.28; H1.78; N 10.00; Mo 8.57, found C33.58; H 1.70; N 9.58; Mo 8.4. Confirmations from visual and infra-red spectra were made. The yield was 15%. Its fluorescence spectrum and effects of solvent and surfactant on the spectra were also studied. Its fluorescence quantum yield (φ_F 0.803) was found to be higher than that of znic tetrasulfophthalocyanine and is the highest one in all known transition metals. Hence the Molybdenum compound could play an important role in forming light energy conversion systems and fluorescent materials.

Key words: Molybdenum, 4,4′,4",4′"-tetrasulfophthalocyanine, Synthesis, Fluorescence
