Langmuir-Blodgett Films of Aromatic Schiff's Bases Functionalized in the Side Chains of Polymethacrylate

Abstract

Langmuir-Blodgett (LB) film formation has been investigated for polymers in which nonlinear optical (NLO) moieties are attached in the side chain of polymethacrylate (PMA) backbone. Polymer monolayer was successfully transferred onto hydrophilic glass substrates using a moving wall type LB trough. The LB films were characterized by pressure-area isotherm, polarized UV- visible spectra, ellipsometry and second harmonic generation measurement. The characterization shows that NLO moieties in the side chain are inclined to the plane of the substrate at a shallow angle. The second order nonlinear coefficient and molecular hyperpolarizability were also calculated.
