Stereoselective synthesis of cyclometalated iridium(III) complexes: Characterization and photophysical properties

The stereoselective synthesis of a highly luminescent neutral Ir(III) complex comprising two bidentate chiral, cyclometalating phenylpyridine derivatives, and one acetylacetonate as ligands is described. The final complex (2) and some derivatives of intermediates (1) were characterized by X-Ray structural analysis, NMR-, CD-, and CPL-spectroscopy.
