Synthesis and characterization of π-conjugated oligomers that contain metal-to-ligand charge transfer chromophores†

Abstract

The synthesis and characterization of a series of p-phenyleneethynylene oligomers that contain the 2,2′-bipyridine-5,5′-diyl moiety is reported; metallation of the oligomers with Re^I(CO)₅Cl and Ru(bpy)₂Cl₂ yields the corresponding (L)Re(CO)₃Cl and (L)Ru(bpy)₂ ²⁺ complexes.
