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-hexyloxy-phenoxy)-undecane-2,4-dione) from [{Ir(μ-Cl)(ppy)2}2], phC6-acacH and silver trifluoroacetate as the halide abstractor in refluxing acetone is described. The crystal and molecular structure of 1 was determined by X-ray crystallography.

The synthesis and the X-ray crystal structure of the cyclometalated iridium(III) complex [Ir(ppy)2(phC6-acac)] (1, ppy = 2-phenylpyridyl, phc6-acac = 11-(2,5-dibromo-4-hexyloxy-phenoxy)-undecane-2,4-dione) is presented. The emission spectrum of 1 exhibits this complex as a green-light-emitting compound.Figure optionsDownload as PowerPoint slide
