Synthesis and Characterization of New π-Conjugated Polymer Complexes with Transition Metal Fragments

Abstract

Poly(2,2′-bipyridine-5,5′-diyl) (PBpy) (1) and a polymer of 2,2′-bipyrimidine (PBpym) (2) afford polymer complexes (3) and (4) coordinated with [Ru(bpy)₂]²⁺ fragments, respectively. The UV-vis spectrum of (4) in conc. H₂SO₄ is considerably different from 2 in conc. H₂SO₄. The poly(6,6-dimethylbipyridine-5,5′-diyl) (P6MeBpy) (5) reacts with a ruthenium complex, [RuClCp*]₄, (Cp*=pentamethylcyclopentadienyl) to give a new ruthenium complex (6).
