Abstract: Aseries of amphiphilic azo methine dyes with different relative positions of electron accepting groups, (E)-Noctadecyl-2-[2-(4-N,N-dimethylaminophenyl)azomethinyl]quinolinium iodide(QN2), (E)-Noctadecyl-4-[2-(4-N,N-dimethylaminophenyl)azomethinyl]quinolinium iodide(QN4) and (E) Noctadecyl-6-[2-(4-N,N-dimethylaminophenyl)azomethinyl] quinolinium iodide(QN6) were synthesized. These dye molecules were successfully transferred onto quartz by Langmiur-Blodgett(LB) technique. We studied the second harmonic generation(SHG) of their monolayers and found that the effect of relative position of acceptor group on SHGcan not be negligible.

Key words: Azo-methine dye, LB monolayer film, Second-harmonic generation, χzzz(2)
