Abstract Novel organometallic poly(arylene)s containing 1,3-type (cyclobutadiene)cobalt moieties in the main chain were prepared by the Ni(0)-mediated dehalogenative polycondensation of monomers having (cyclobutadiene)cobalt moieties. The resulting poly(arylene)s were partly soluble in organic solvents and the number-average molecular weights (M n) of soluble fractions were estimated to be 16,700–22,000 by GPC. The polymers showed the formation of a π-conjugated structure, good solubility in common organic solvents, and thermotropic liquid crystallinity.
