Rod-like ruthenium(II) coordination polymers: synthesis and properties in solution

Well defined coordination polymers obtained via the conversion of 4,4″-bis(2,2′:6′,2″-terpyridine)-2′,5′-dihexyl-p-terphenyl and activated ruthenium(III) show intrinsic viscosities of up to [η] ≈ 300 mL g–1 and a tremendous polyelectrolyte effect in salt-free DMA solution proving both their high molecular weights and considerable chain stiffness.
