Towards a phosphorescent cyclometalated iridium complex containing a modified polymerizable acetylacetonato ligand

A convenient synthesis of the complex [Ir(ppy)(2)(phC6-acac)] (1, ppy = 2-phenylpyridyl, phC6-acac = 11-(2,5-dibromo-4-hexyloxyphenoxy)-undecane-2,4-dione) from [{Ir(mu-Cl)(ppy)(2)}(2)], phC6-acacH and silver trifluoroacetate as the halide abstractor in refluxing acetone is described. The crystal and molecular structure of I was determined by X-ray crystallography
