Studies on phthalocyanine sheet polymers
2004
Abstract Cobalt, nickel and copper phthalocyanine sheet polymers are synthesized by heating their respective metal (II) phthalocyanine tetracarboxylic acids at 400 °C in nitrogen atmosphere. These polymers are characterized using UV–Visible spectra, IR spectra, magnetic susceptibility, X-ray powder diffraction and thermogravimetric analysis. Electrical conductivity studies are carried out using two-probe technique in the temperature range 25–200 °C for each polymer. These polymeric materials showed room temperature electrical conductivity 10–1000 times higher values compared to earlier reported values for this type of sheet polymers.
