Unprecedented and Readily Tunable Photoluminescence from Aliphatic Quaternary Ammonium Salts [PDF]
Compounds bearing aliphatic amines could be emissive under proper conditions. Their ionized counterparts, quaternary ammonium salts (QASs), which are widely used as phase-transfer catalysts, ionic liquids, disinfectants and surfactants, however, are ...

Sustainable Triazine-Based Dehydro-Condensation Agents for Amide Synthesis
Conventional methods employed today for the synthesis of amides often lack of economic and environmental sustainability. Triazine-derived quaternary ammonium salts, e.g., 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM(Cl ...
