Synthesis of Highly Soluble Fluoro Containing Metal -phthalocyanines and (Hexafluoroisopropylidene) -bridged Metal-phthalocyanine Polymers


NOVEL soluble peripherally tetrasubstituted metal-phthalocyanines: 2(3),9 10), ……16 (17),23(24) – tetrakis - 2'-(4-hexafluoroisopropylidene-phthalic acid)-phthalocyanines [(R4Pc)M] where R= (4,4`-(hexafluoroisopropylidene) bis-phthalic acid and M= Co(II), Ni(II) and Cu(II) 2-4, have been prepared. Additionally, the soluble hexafluoroisopropylidene bridged high molecular weight phthalocyanines 5-7 were obtained by controlling the reaction conditions such as molar ratio of the reactant, reaction time and temperature. Structural and spectral investigations (FAB-MS, MALDI-TOF-MS, 1H-NMR, atomic absorption spectroscopy (AAS), elemental analysis, UV/Vis, FTIR, TGA, and GPC) of the prepared phthalocyanines revealed some interesting observations.
