Emissive Metallomesogens Based on 2-Phenylpyridine Complexes of Iridium(III)
摘要:
Preparation of hill complexes using anisotropic 2,5-di(4-alkoxyphenyl)pyridine ligands leads to emissive, liquid-crystalline complexes containing bound CI and dimethyl sulfoxide. Using analogous poly(alkoxy) ligands allows the preparation of bis(2-phenylpyridine)iridium(III) acac complexes, which are also mesomorphic. The observation of liquid crystallinity in octahedral complexes of this type is without precedent.

There is described a non-planar iridium-ligand complex with accessible triplet states and a molecular structure that confers liquid-crystal like properties.

A good combination: Dimeric iridium(III) luminophores with tetraacetylethane bridges led to liquid‐crystalline materials with very high photoluminescence quantum yields (see picture). The same design principle allowed for the preparation of heteronuclear iridium(III)–platinum(II) dyads, which were also luminescent.
