A class of beryllium complexes has been synthesized. These complexes display crystalline-enhanced emission (CEE) and exhibit morphology-dependent dark and bright red/NIR fluorescence. They show bright red/NIR emission in the crystalline form (λem: 635–700 nm; Φf: 0.27–0.40) and faint emission in the amorphous state. Their emission can be smoothly switched “ON” and “OFF” by simple grinding/solvent annealing

A novel family of organoboron compounds 1-4 with bright near-infrared (NIR) emissions in the crystalline state was synthesized. They show a morphology-dependent emission "ON" and "OFF" feature and volatile acid/base-induced fluorescence saltation which allow the realization of reversible solid-state fluorescence switching in the NIR region by totally different procedures: mechanical grinding/solvent annealing and acid/base vapor fuming.
