New heterometallic Ir(iii)2–Eu(iii) complexes: white light emission from a single molecule†
Abstract
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.
