Abstract

Poly(thienylene ketone)s are formed by the copolymerization of bis(chloromercuri)thiophenes with carbon monoxide. The reaction is carried out in hot pyridine with a Pd catalyst under 500 psi of CO. The polymers, poly(3-methylthienylene ketone), poly(3-butylthienylene ketone), and poly(3-(carboethoxymethyl)thienylene ketone), with molecular weights, Mn, ranging from 1600 to 2700, were produced. The polymers have UV−vis absorption maxima near 360 nm, assigned to π−π* transitions, and are reduced irreversibly near −1.0 V vs SCE.
