Abstract A successful synthesis of new meso-tetracuperatedporphyrin-schiff's complex was achieved from metallo5, 10, 15, 20-tetrakis(4-hydroxyphenyl) porphyrin (M=Cu(II), VO(II) & Ni(II)) and salicylideneamino-2-(N, Ndimethylamino)ethane copper (II) perchlorate under nitrogen atmosphere. Similarly meso-tetrazincporphyrinschiff's complex derived from 5, 10, 15, 20-tetrakis(4-hydroxyphenyl) porphyrinato copper (II) and salicylideneamino-2-(N, N-dimethylamino)ethane zinc(II) chloride synthesized as control experiment. Detailed spectral analysis reveal dipolar interaction between the core copper metal ion of the porphyrin and meso-copper ions however no interaction between core vanadyl and meso-copper ions. Furthermore, the ease with which the copper at the periphery undergoes oxidation and reduction has been understood from the electrochemical investigation. The results also reveal a change in the geometry of the meso-copper after coordination to the porphyrin. Top Keywords Porphyrin, tetracuperated, physico-chemical, voltammetry, redox potential. Top |
