Solid-State Characterization of a Fused Salphen–Nickel Metallopolymer Prepared via Transmetalation in a Heterogeneous Reaction System

A nickel-containing metallopolymer with fully π-conjugated fused salphen ligands was prepared from the corresponding zinc-containing metallopolymer by means of transmetalation. As a model for the metallopolymer, an analogous fused tetrasalphen–nickel complex was also prepared. Solid-thin-film absorp...

Summary:A nickel-containing metallopolymer with fully π-conjugated fused salphen ligands was prepared from the corresponding zinc-containing metallopolymer by means of transmetalation. As a model for the metallopolymer, an analogous fused tetrasalphen–nickel complex was also prepared. Solid-thin-film absorption microspectroscopy was used to confirm that the transmetalation reaction had occurred and to determine the degree of polymerization, which was estimated to be 8–15. Combined with theoretical normal-mode analysis, comparison of the FT-IR spectra of a series of model complexes with different nuclearities revealed two diagnostic peaks that could be used to validate the polynuclearity of the nickel-containing metallopolymer.
