摘要： 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 having an electron donor moiety linked through a conjugated .pi. bonding system to an electron acceptor moiety to permit oscillation of the molecular dipole between a ground state exhibiting a first dipole moment and an excited state exhibiting a differing dipole moment. The molecular dipoles are held in polar alignment by a crosslinked polymeric binder.

摘要： An optical article, for the transmission of electromagnetic radiation. The optical article includes a medium, which exhibits a second-order electric susceptibility greater than 10.sup.-9 electrostatic units. The medium includes polar aligned dipole subunits. Each dipole subunit has a plurality of noncentrosymmetric molecular dipoles and a connector system. Each molecular dipole has an electron donor moiety, an electron acceptor moiety, and a linking moiety. The linking moiety has a pair of covalent bonds to the connector system. Each molecular dipole has a conjugated .pi. bonding system extending from the electron donor moiety along the linking moiety to the electron acceptor moiety to permit oscillation of the molecular dipole between a ground state and an excited state, which states differ in polarity. The connector system joins the linking moieties to complete a solitary ring or a system of fused rings, which retain the molecular dipoles in substantially parallel relative relation.

摘要： 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 a linear polymer containing as pendant groups polar aligned noncentrosymmetric molecular dipoles having an electron donor moiety linked through a conjugated .pi. bonding system to an electron acceptor moiety to permit oscillation of the molecular dipole between a ground state exhibiting a first dipole moment and an excited state exhibiting a differing dipole moment. The linear polymer contains repeating units derived from vinyl addition polymerization, at least 5 percent of the repeating units incorporate the molecular dipoles as pendant groups, and the molecular dipoles include a sulfonyl electron acceptor moiety.

摘要： In a preferred embodiment, poly(4-phenylsulfone) is prepared by self-condensation of sodium 4-fluorophenyl sulfinate. The process is initiated by a small quantity of 4,4'-difluorophenylsulfone. The process is conducted in the presence of a dipolar, aprotic solvent such as dimethylsulfoxide. The reaction is conducted at a mildly elevated temperature, preferably within the range of from about 100.degree. C. to about 200.degree. C.
