Synthesis, Optical and Surface Properties of the New Gemini Quaternary Ammonium Surfactants Containing DSD Acidtriazine Structure
Four novel gemini quaternary ammonium surfactants containing DSD acid-triazine structure were synthesized using a facile three-step synthetic route,from 4,4-diamino-2,2-disulfonic-stilbene (DSD acid),cyanuric chloride and dimethyl dodecylamine.The structures and optical properties of compounds (6a-d) were characterized by Fourier-Transform infrared (FTIR) spectroscopy,UV-visible absorption spectra and fluorescence emission spectrum.The surface tension and the Critical Micelle Concentration (CMC) were evaluated.The result shows that the four compounds at lower concentrations can greatly reduce the surface tension of aqueous solutions.The spectroscopic properties of these quaternary ammonium salts are assessed for their effectiveness and potential as fluorescent brightening agents.
