We synthesized a linear structure of organic-metallic hybrid polymers by complexation of iron(II) acetate with novel bis-terpyridines bearing alkoxy chains as an electro-releasing group. Introduction of alkoxy groups to bis-terpyridines was achieved during a reaction of bromo-substituted bis-terpyridines with sodium alkoxide in DMF. When we use alkane-diol as a starting material, a unique bis-terpyridine with a cyclic structure obtained via intramolecular cyclization. Formation of the corresponding hybrid polymers based on complexation of the organic module with iron(II) ions was confirmed as increase of a MLCT absorption in the UV-vis spectral measurements. We found that a blue shift of the MLCT absorption is caused by introduction of electro-releasing groups to the organic modules.
