    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 ......
