Second Harmonic Properties of Aromatic Schiff's Bases Functionalized in the Side Chains of Polymethylmethacrylate

Abstract

Polymeric thin films doped with NLO molecules are easily prepared. Recently, we have reported a number of new homo- and co- polymers in which the NLO molecules separated by flexible methylene spacer are covalently attached in the side chain of polymethacrylate (PMA) backbone. Aromatic Schiff's bases substituted with appropriate donor acceptor groups have been chosen because of their high ground-state dipole moment and large molecular hyperpolarizability. In this report, the synthesis, characterization, non-linear optical properties and preparation and characterization of mono or multilayer films of new side chain polymers are presented and discussed.
