Synthesis and electrochemistry of nickel(II)porphyrins bearing external palladium(II) or platinum(II) complexes

The syntheses of nickel(II)porphyrins bearing palladium(II) or platinum(II) complexes at their periphery were performed. These new compounds characterized by standard spectroscopic techniques and studied electrochemistry. electrochemical data then compared with previously published porphyrin dimers linked metal ions like platinum(II). An X-ray structure one these species was obtained confirmed the this series compounds.
