Preparation of thin films with well-defined molecular orientation of chromophores by polymerization of liquid crystalline monomers in an electric field

Abstract

Mixtures of mono- and di-acrylates showing a nematic phase are polymerized in an electric field to make thin films with homotropic molecular orientation; the orientation of chromophores in the thin films depends on the direction of the dipole moment of the liquid crystalline monoacrylates.
