Phosphorescent mesomorphic dyads based on tetraacetylethane complexes of iridium(III)

Abstract

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. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
