Abstract:
Three compounds of metalloporphyrins were studied using electrospray ionization mass spectrometry.The bonding power between substitutional phenyl and porphyrin cycle and the coordinate conditions of metalloporphyrins with imidazole were disscused. The experimental result indicated that the bonding power between substitutional phenyl and porphyrin cycle in metalloporphyrins became weak from Mn,Fe to Co.The complexes abundances formed by metallophorphyrin with imidazole were stronger with the increase of the ligand concentration.At the same ligand concentration,the abundance of the complexes was intensified gradually and the stability of the ligands was become stronger from Mn,Fe to Co.
