Langmuir–Blodgett film properties of a donor–acceptor Schiff base

A low-molecular weight Schiff base with donor–acceptor substituent on the Schiff base has been synthesized in order to study the Langmuir–Blodgett (LB) film properties. This is the first report wherein we demonstrate a short chain, Schiff base forms stable monolayers which have been transferred onto solid substrates to prepare Langmuir–Blodgett multilayers. Spectroscopic measurements of this Schiff base in chloroform as well as its LB film show changes in the spectral features indicating the changes in the environment around the chromophore.
