White-light emission from a pyrimidine–carbazole conjugate with tunable phosphorescence–fluorescence dual emission and multicolor emission switching

Abstract

A metal-free organic carbazole–pyrimidine dye exhibiting phosphorescence–fluorescence dual emission was developed into a white-light emission-switching system. The two crystal polymorphs obtained by breaking the molecular symmetry responded to the external stimuli of heating, vapor-fuming, and mechanical grinding, resulting in a tricolor switching system that includes white-light emission.
