Allochroic cluster light-emitting diodes based on unique μ₃-tetraphosphine Cu₃X₃ crowns with tunable excited states.

ABSTRACT: Multicomponent excited states endow copper iodide clusters with allochroic properties under diverse stimuli. However, crystal states are required, and cluster stimulus sensitivity hampers electroluminochromism. We developed PhQPCu₃X₃ (X = Cl, Br, and I) with the first μ₃-bridging tetraphosphine ligand, whose Cu₃X₃ crowns were exposed to external stimulus. The increased proportion of Cu₃X₃ results in equal contributions of cluster- and ligand-centered components to excited states, the former of which is highly sensitive to grind, vapor, and, especially, electric stimuli, due to semi-exposed Cu₃X₃. Through vacuum evaporation and vapor fumigation of cluster-based emissive layers, the diodes' ele
