Abstract

Abstract We found aromatic copolymers comprising 4′-hydroxy 4-biphenyl carboxylic acid and 6-hydroxy 2-naphthoic acid with high second-harmonic-generation (SHG) activity. The polarization dependence of SHG in the solid film formed from the nematic phase reveals uniaxial and biaxial polar orderings.
