Paper Abstract

To induce macroscopic second-order nonlinear optical properties in polymers containing polar, hyperpolarizable groups like DANS or MONS, these groups have to be polarly aligned (poled) with a strong electric field at the glass transition temperature. Simple molecular statistical models, which neglect dipole-dipole interaction, predict an enhancement of the electric field induced polar order by axial order. Since axial order exists spontaneously in liquid crystals, the introduction of liquid crystalline properties into the poled polymer has been considered as advantageous. The presumed advantage for poling from axial order, in particular from liquid crystalline axial order, is discussed in the light of more recent theoretical calculations and experimental results.
