碩士 === 國立中興大學 === 化學系所 === 102 === We use 4-Methylbenzyl bromide as 2-N substituted alkylation to react with N-confused porphyrin to afford 2-aza-2-(p-methylbenyl)-5, 10, 15, 20-tetraphenyl-21-carbaporphyrin (2-NCH2-p-C6H4CH3NCTPPH) (2). After 2-N substituted alkylation, we use Ni(OAc)2∙4H2O, CoCl2∙6H2O to react seperately with 2-NCH2-p-C6H4CH3NCTPPH (2) to get two NCP metal complexes, diamagnetic of Ni(2-NCH2-p-C6H4CH3NCTPP) (3)、paramagnetic of Co(2-NCH2-p-C6H4CH3-21-CH2-o-C6H4CH3NCTPP)Cl (4). we use X-ray single-crystal diffractometer to study the crystal structures of NCP metal complexes The magnitudes of axial (D) and rhombic (E) zero-field splitting (ZFS) for the mononuclear Co(II) in 4 were determined approximately as 39.14 cm-1 and 8.61 cm-1 respectively by paramagnetic susceptibility measurements and conventional EPR spectroscopy.
