Side chain liquid crystalline polymers which exhibit nonlinear optical responses, particularly second and third harmonic generation, are presented together with methods for making them. These polymers derive their nonlinear optical behavior from selective pendant groups that are attached via spacers to the backbone. Several embodiments having chiral structures are subject to efficient dipolar and molecular alignment by electric field poling. The methods disclosed for making these polymers are polycondensation, graft polymerization, and copolycondensation.
