Abstract

A series of structurally simple yet highly tunable organoboron luminophores was designed and synthesized. The solid-state fluorescence quantum yields exhibit nearly exponential growth by decorating the luminophore with additional sterically demanding substituents. Uniquely, the luminescence of these organoboron dyes can be easily switched on/off by acidic/basic vapors, yielding a solid-state fluorescence switching function.
