Abstract: The FTIRspectra(3600~150 cm-1)of bisteraphenylmetalloporphyrin dimers linked by a flexible alkoxy chain were measured and investigated.The major bands have been empirically assigned in comparison with a large number of porphyrins and metalloporphyrin complexes.The metal sensitive bands were found at 1558;2,l472.2,1401.9,1350.5,l 001.7,965.9,877.3 and 798.8 cmr) The structure sensitive bands of both the metal and the alkoxy chain were found at l 595.1,1491.1,851.1 and 723.8cm-1.The vMn-Cl and -1,vFe-Cl were found at 3l8.2 and 371.4 cm-1 respectively.The vibration coupling between the M──N and the porphyrin ring deformation is Co(Ⅱ)>Mn(Ⅲ)>Fe(Ⅲ).The vibration coupling between the M-Nstretching modes and the porphyrin ring deformation is MP>Mp-MP.The vibration coupling between the M-Nbending modes and the porphyrin ring deformation is MP<MP-MP.
