Compounds emitting from a thermally activated delayed fluorescence (TADF) mechanism can harvest both singlet and triplet excitons, which traditional fluorescent emitters are unable to achieve. OLEDs fabricated from these materials have achieved impressive and competitive performance compared to traditional phosphorescent emitters based on expensive iridium(III) and platinum(II) rare metals. In this poster, I will present our recent work on small molecule organic TADF emitters for electroluminescent devices.  These materials offer a cheaper and more sustainably alternative to phosphorescent materials, which are the present state-of-the-art materials.
