Abstract
An optical article is disclosed containing, for the transmission of electromagnetic radiation, a medium exhibiting a second order polarization susceptibility greater than 10.sup.-9 electrostatic units comprised of polar aligned noncentrosymmetric molecular dipoles. The molecular dipoles have a hydrophobic electron donor moiety linked through a conjugated .pi. bonding system to an electron acceptor sulfonyl moiety. The electron acceptor sulfonyl moiety includes at least two halogen substitutents of its .alpha. carbon atom.
