一分子内にアゾベンゼン単位を二個有する両親媒性物質の合成

抄録

Five new amphiphiles each containing two azobenzene units in a molecule were synthesized through four reaction steps. The first step was azo-coupling reactions with aniline derivatives and phenol. The second step was Williamson etherification reaction between sodium salts of phenols containing an azobenzene unit with ω-halogenated alcohols, such as 2-bromoethanol or 3-chloro-l-propanol. The third step was diesterification reactions between alcohols having an azobenzene unit and maleic anhydride, the diester of maleic acid containing two azobenzene units in a molecule was obtained. The fourth step was addition reaction of sodium hydrogensulfite with diesters. The products were characterized by 1H-NMR, IR, and Mass spectra.
