New heterometallic Ir(III)(2)-Eu(III) complexes: white light emission from a single molecule

The design of a relatively simple bifunctional ligand led to the obtainment of three new Ir(III)(2)-Eu(III) heterometallic complexes. Variation of the degree of fluorination in the cyclometalating ligands coordinated to the Ir(III) centres allows tuning of the photophysical properties and pure white light emission from a single complex.
