Synthesis of Novel Bis(terpyridyl)benzene Derivatives as Organic Modules in Organic-Metallic Hybrid Polymers

Abstract

As novel organic modules in organic-metallic hybrid polymers, bromo-substituted bis(terpyridyl)benzenes were prepared via condensation of aromatic dienones with pyridinium salts in the presence of ammonium acetate. The organic-metallic hybrid polymer was obtained by complexation of dibromo-substituted bis(terpyridyl)benzene with iron(II) acetate. We investigated electrochemical and spectroscopic properties using cyclic voltammetry and UV-vis spectral measurement and revealed a substituent effect of the bromo groups.
