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.
