Sky Blue and Yellow Cluster Light-Emitting Diodes Based on Asymmetric Cu₄I₄ Nanocubes.

ABSTRACT: Controllably optimizing excited-state characteristics is crucial for luminescent nanoclusters but remains a formidable challenge. Herein, we report an effective "ligand-induced asymmetrization" strategy for constructing thermally activated delayed fluorescence-featured cubic Cu₄I₄ nanoclusters with asymmetric configurations, named [tBCzDBFDP]₂Cu₄I₄ and [PTZDBFDP]₂Cu₄I₄. Through changing 3,6-di-tert-butyl-carbazole (tBCz) to phenothiazine (PTZ) with a stronger electron-donating effect, emission color is tuned from greenish blue of [tBCzDBFDP]₂Cu₄I₄ to yellow of [PTZDBFDP]₂Cu₄I₄, as well as the triplet locally excited state of the fo
