2,6-Bis(arylsulfonyl)anilines as Fluorescent Scaffolds through Intramolecular Hydrogen Bonds: Solid-State Fluorescence Materials and Turn-On-Type Probes Based on Aggregation-Induced Emission
A series of 2,6-bis[aryl(alkyl)sulfonyl]anilines were synthesized by nucleophilic aromatic substitution of 2,6-dichloronitrobenzene with various aryl or alkyl thiolates (benzyl-, phenyl-, 2-naphthyl-, and 2-aminophenyl thiolate), followed by hydrogenation and subsequent oxidation. All prepared 2,6-bis[aryl-(alkyl)sulfonyl]anilines showed high fluorescenceemissions in the solid state; X-ray structures
