Studies on molecular structure of Schiff base derivatives in LB films

The present paper investigated the molecular configurations of the two novel amphiphiles with Schiff base moiety as headgroup in LB films. FTIR-ATR spectra and UV-vis electronic absorption spectra revealed the different isomers between the two amphiphiles LB film. Since -OH groups situate in different position of the aromic rings in Schiff base amphiphiles, the proton transfer by different ways leads to different isomers, which were reflected by monolayer and LB films behavior.
