ABSTRACT:
Devices and materials containing certain stable, polycyclic aromatic compounds exhibit sensible, second order nonlinear optical effects. In general, useful polycyclic aromatic compounds possess electron-donating and electron-withdrawing chemical functionality but no center of inversion symmetry on either the molecular or crystalline unit cell level.
