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.
