Abstract

The purpose of this study was to synthesize novel amphiphiles that are NLOactive and incorporate these amphiphiles into polyelectrolyte films. The amphiphiles have a long aliphatic chain with a polar head (sulfonate) and a donor-pi system-acceptor moiety that will exhibit NLO responses. The first compound, sodium 10-[4-(4-nitrophenyl azo)-phenoxy]-decane-l-sulfonate (NOAS), was synthesized in a very low yield with most of the obtained product containing seven times as much unreacted bromide. The second compound, sodium 10-[4-(4-cyano-phenyl azo)-phenoxy]-decane-lsulfonate (CNAS), was synthesized in a 3:1 ratio of sulfonate to bromide. Before it was known that impurities were present polyelectrolyte multilayers (by the dipping method and spin assembly) were made with both products. The CNAS product deposited in polyelectrolyte layers more than the NOAS product because it contained more sulfonate product. Deposition was further proved by ellispometric thickness measurements. The polyelectrolyte studies will be redone with pure product in the near future.
