Comparison of Axial Imidazole Binding Strengths in Co(III), Fe(III) and Mn(III) Porphyrinoid Complexes as Studied by Tandem Mass Spectrometry

摘要

1. All metal(II) porphyrins can simultaneously bind with one as well as two Imidazole ligands 2. The binding order for square pyramidal complex is Fe>Mn>Co, except Porphyrin 11 which shows highest binding for Mn and lowest for Co.
