Abstract

Abstract : Several examples of a new class of materials which exhibit thermally‐activated delayed fluorescence (TADF) were designed and synthesised. Structure‐activity relationships were explored in order to colour‐tune the fluorescence (from yellow to blue) and to improve the luminescence quantum yield. Device architectures were optimised for four materials in this class. Notably, the yellow device (CIE1931xy coordinates 0.407, 0.557) displays a maximum external quantum efficiency (EQE) of 14.3%.
