The Ideal

In consideration of the Sm3þ-centered characteristic orange-light as the ideal color-primary component toward a dichromatic white-light, herein, through the doping of the complex [Sm(acac)3(5-Br-2,20-bpy)] (2; Hacac ¼ acetylacetone; 5-Br-2,2′-bpy ¼ 5-Br-2,20-bipyridine) into the PVK (PVK ¼ poly(N-vinyl-carbazole)) host, the obtained PVK@2 film (10:1, wt/wt) exhibits the straightforward solid-state white-light (ΦPL ¼ 6.7%). Further using the PVK@2 film (10:1; wt/wt) as the emitting layer, its singlecomponent solution-processed WPLED gives the electroluminescent performance (LMax of 360.9 cd/m2, ηMax c of 1.08 cd/A) satisfactory enough for portable full-color flat displays

Stimuli Response

Novel maleic anhydrides symmetrically substituted by two aromatic rings exhibit distinct emission behaviours: aggregation-caused quenching (ACQ), aggregation-induced emission (AIE), and dual-state emission (DSE) in both solution and the solid state. Appropriate modifications were made to turn ACQ/AIE into DSE and realize full-color DSE.
