摘要：

A series of iron(III)-metal-porphyrin dimers linked with flexible alkoxyl chain at para position of two phenyl rings have been synthesized and characterized. An equilibrium of two conformations of porphyrin dimers(open and closed)has been studied by visible spectra. The intensity of absorption band 680 nm relates to equilibrium of two conformations. With the increase of the length of the alkoxyl chain, the closed conformation forms more easily. With the addition of axial ligand, the ferric ion of the dimers tends to bind with imidazole,and the intensity of the band 680 nm gradually decreases and disappears.
