TL;DR: In this article, the electro-optic properties of nonlinear optical polymer with self-crosslinkable groups in the side chain were investigated, and successful strategies for simultaneous poling and selfcrosslinking during the poling without addition of crosslinking agents were presented.

TL;DR: In this article, the major interaction between the electric field of the electromagnetic radiation and the charge distribution within an optically transparent material is discussed. But the main focus of the paper is on the structural features of the material which allow it to happen.
Abstract: Chemists specializing in synthesis who attempt to come to terms with the theoretical physics associated with nonlinear optical behaviour of materials frequently encounter a highly repulsive intellectual energy barrier, and I am no exception to this generalization. However, as in many other fields of activity lying at the interface between solid state physics and chemistry, this field of research needs contributions from synthetic chemistry if it is to progress and, if the role of 'plumber's mate' is to be avoided, the chemist attempting to make a contribution requires a picture of what is involved in nonlinear optic phenomena. At the simplest level the questions are 'What happens?' and 'What are the structural features of the material which allow it to happen?' The descriptive remarks presented below attempt to answer this need and to provide relevant background to the main body of the paper. Readers seeking more detailed and properly rigorous treatments of the subject are referred to more authoritative sources (Chemla 1987; Shen I984; Williams 1984). After this brief nod in the direction of physics and technology the bulk of the paper will be concerned with the synthesis and properties of materials. When light passes through an optically transparent material it interacts with it. The major interaction is that between the electric field of the electromagnetic radiation and the charge distribution within the material. This interaction induces a polarization P within the material that is related to the electric field E of the radiation by the expression,

TL;DR: In this article, the generalized Thomas-Kuhn sum rules are used to characterize the nonlinear response of organic chromophores in terms of fundamental parameters, and different strategies for the enhancement of nonlinear behavior at the molecular and supramolecular level are evaluated and new paradigms for designing more efficient nonlinear molecules are proposed.
Abstract: We present a theoretical and experimental study of the molecular susceptibilities. The generalized Thomas-Kuhn sum rules are used to characterize the nonlinear response of organic chromophores in terms of fundamental parameters. The nonlinear optical performance of real molecules is evaluated from the calculation of the quantum limits and Hyper-Rayleigh scattering measurements. Different strategies for the enhancement of nonlinear behavior at the molecular and supramolecular level are evaluated and new paradigms for de design of more efficient nonlinear molecules are proposed.

TL;DR: In this paper, a novel functionalized second order nonlinear optical (NLO) chromophores have been prepared with functionalized aniline as electron donor, thiophene or isophorone as π-spacer and 1,3-diethyl-2-thiobarbituric acid as electron acceptor.

TL;DR: An amphiphilic lanthanide complex, (E )-1-methyl-4-(2-(4-(dihexadecylamino)phenyl)azo)pyridinium tetrakis(1-phenyl-3-methyl,4-benzoyl-5-pyrazolonato)lanthanum(III), has been synthesized as mentioned in this paper.
