Abstract

Homogeneous reaction of soluble poly(n-hexylphenylene) (PHP) with a molybdenum carbonyl complex, (py)₃Mo(CO)₃, afforded an organometallic π-conjugated polymer at ambient temperature. The product was soluble in common organic solvents such as chloroform or THF and its infrared and UV-visible absorption spectra and electrochemical properties indicated a formation of (η⁶-arene)Mo(CO)₃-type complex polymer, PHP-Mo(CO)₃. The ratio of Mo(CO)₃ units to benzene rings in PHP-Mo(CO)₃ was estimated at 1 5 from the ratio of v(CO) and v(CC) peak absorbances in the infrared spectrum and by the colorimetric analysis of Mo content. Reaction of poly(n-butylphenylene) (PBP) with chromium hexacarbonyl also afforded a organometallic polymer containing Cr(CO)₃ moieties, PBP-Cr(CO)₃. Conductivity of PHP-Mo(CO)₃ and PBP-Cr(CO)₃ was higher than that of free PHP and PBP, respectively, in the neutral state, although the activation energy for the conductivity is not seriously changed by the complex formation.
