Abstract:Aiming at the fabrication of circularly polarized organic light‐emitting diodes (CP‐OLEDs) with high dissymmetry factors (gEL) and color purity through the employment of novel chiral source, topologically chiral [2]catenanes were first utilized as the key chiral skeleton to construct novel multi‐resonance thermally activated delayed fluorescence (MR‐TADF) emitters. Impressively, the efficient chirality induction and unique switchable feature of topologically chiral [2]catenane not only lead to a high |gPL| val… Show more
