In a method of forming a polyaryl polymer, a fluorosulfonate-containing monomer is coupled with itself or a boron-containing comonomer in the presence of a catalyst and a base. The resulting polymers can be used as precursors to electrically conducting polymers, and as components of resist or underlayer compositions for photolithography, among other applications.

The present invention relates to an organic/heterometallic hybrid polymer including a plurality of organic metal complexes and a plurality of transition metals, the organic/heterometallic hybrid polymer, wherein

the plurality of organic metal complexes are linked in a linear manner by sandwiching each of the plurality of transition metals therebetween,

the organic metal complexes include two ligands each having a terpyridyl group and one connector having Ru(dppe).sub.2 and two ethynylene groups, and the two ligands are linked by the connector, so that a nitrogen atom at position 1 of the terpyridyl group is directed toward the terminal side of the molecule of the organic metal complex, and

the terpyridyl groups of at least two different organic metal complexes of the plurality of organic metal complexes are bound to one of the transition metals through a coordinate bond, thereby linking the plurality of organic metal complexes while sandwiching the plurality of transition metals alternately therebetween.
