Synthesis, Mesomorphic and Molar Conductivity Studies of some Macrocyclic Phthalocyanine Palladium (II)
Abstract
Two series of Macrocyclic Phthalocyanine Palladium(II) namely 4,4,4,4-RnPcPd and 3,3,3,3-RnPcPd were prepared and characterized. The mesomorphic investigation by hot stage polarizing microscope for these series was carried out. This investigation revealed that the 4,4,4,4-RnPcPd series exhibited columner mesophases while the second series 3,3,3,3-RnPcPd did not show any liquid crystalline properties.The molar conductivity measurments carried out in dimethyl sulfoxide and N,N-dimethyl formamide solvents for all prepared compounds at room temperature indicate that these compounds behave as weak electrolytes .
Keywords: Macrocyclic compounds, Macrocyclic complexes, Liquid Crystals, Conductivity.
