A Novel π-Conjugated Organometallic Polymer, Molybdenum Tricarbonyl Modified Poly(n-hexylphenylene)

Abstract Electrochemical and electrical properties of soluble poly(n-hexylphenylene) bound to Mo(CO)3 were investigated by cyclic voltammetry, spectro-electrochemistry and four-electrode voltammetry. Oxidation of the Mo complex polymer occurs at E0′ = 0.51 V vs. Ag/Ag+, which is less positive than that of free poly(n-hexylphenylene) by ca. 0.3 V. At this potential, conductivity of the Mo complex polymer increases. The band gap of the polyphenylene does not change significantly by coordinating to Mo.
