Phosphole oxides undergo a highly chemoselective reaction with sulfonyl isocyanates forming sulfonylimino phospholes in high yields. This facile modification proved to be powerful tool for obtaining new phosphole-based aggregation-induced emission (AIE) luminogens fluorescence quantum yields the solid state. Changing chemical environment of phosphorus atom phosphole framework results significant shift maximum longer wavelengths.
