DC ELECTRICAL CONDUCTIVITY OF TETRA-DIIMINOBENZENE-P-AMINOBENZENEPHTHALOCYANINATO METAL (II) & (III)
In this work a complex of Schiff base of tetra-diiminobenzene-P-amino benzene-phthalocyaninato with tetra diimino-benzene as peripheral groups. The compounds were synthesized with different central metal ions(Al, Fe, Cu and Zn) were synthesized, identified by elemental analysis and spectroscopically, their dc electrical conductivity of their thin films were measured with and without iodine doping. The dc electrical conductivity of iodine doped thin films of the compounds were compared with iodine un-doped thin films of the compounds. The study shows that the measured dc electrical conductivity of the doped Schiff base has higher dc conductivity than un-doped. It shows that the conductivity of the bridged phthalocyanines of aluminum Schiff base has higher dc conductivity than the others, while planar phthalocyanines of zinc Schiff bases has lower dc conductivity. The study, also, shows that the peripheral groups on the phthalocyanine rings as the Schiff base have clear influence on the dc conductivity of all compounds. The stacking and the bridging of the phthalocyanine rings has also effect on the dc electrical conductivity. The bridged compounds have higher conductivity than unbridged compounds.
