Hybrid Redox Polyethers: Molecular Melts of Metalloporphyrins

摘要

The polyether appendages provide a weakly corrdinating "solvent" for the porphyrin centers, and the introduction of ligands like pyridine and carbon monoxide at the gas/melt interface causes changes in Fe(III/II) voltammetry consistent with axial coordination in the semisolid melt. The axial coordination and voltammetric change is reversed by removing the ligand from the bathing gas.
