ABSTRACT 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 (FT-IR) 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.
