TL;DR: In this article, the synthesis and structural characterization of new picoline derivatives, 5-ethyl-2-(4-nitro-7-ol-styryl)-pyridine, space group Pcab, a = 8.628, b = 10.405, and c = 31.604(5) A.
Abstract: Because of their strongly delocalized π electronic systems, polymeric and non-polymeric aromatic compounds show high nonlinear optical properties. The present work deals with the synthesis and structural characterization (including X-ray single crystal studies) of new picoline derivatives, 5-ethyl-2-(4-nitro-styryl)-pyridine, space group P $${\bar 1}$$ a = 6.9505(7), b = 7.418(1), c = 13.877(2) A, α = 105.14(1), β = 93.88(1), γ = 105.89(1)°, and 5-ethyl-2-(4-nitro-7-ol-styryl)-pyridine, space group Pcab, a = 8.628(2), b = 10.405(2), and c = 31.604(5) A.

TL;DR: In this article, a self-consistent theory for the description of the optical linear and nonlinear response of molecules is introduced based strictly on the results of the experimental characterization, which can be used as a guide towards the modeling in terms of fundamental physical parameters.
Abstract: We introduce a self-consistent theory for the description of the optical linear and nonlinear response of molecules that is based strictly on the results of the experimental characterization. We show how the Thomas-Kuhn sum-rules can be used to eliminate the dependence of the nonlinear response on parameters that are not directly measurable. Our approach leads to the successful modeling of the dispersion of the nonlinear response of complex molecular structures with different geometries (dipolar and octupolar), and can be used as a guide towards the modeling in terms of fundamental physical parameters.

  • ...New and more efficient nonlinear-optical materials are needed for the development of applications such as all-optical information, storage and retrieval.[1-3] Currently, long-haul optical data transmission systems are based in the use of inorganic piezoelectric single crystals, such as LiNiO3 , in conjunction with laser diode sources to provide electro-optic amplitude modulation....

TL;DR: In this paper, a novel concept to obtain the highly aligned p-nitroaniline(p-NA) crystals in poly(oxyethylene)(POE) matrix is briefly reviewed.
Abstract: A novel concept to obtain the highly aligned p-nitroaniline(p-NA) crystals in poly(oxyethylene)(POE) matrix is briefly reviewed. The measurements of second harmonic coefficient for POE/p-NA system exhibiting efficient SHG activity were made by Maker-fringe method. The value of d33 is 39 x 10-9 esu at 1.064μm resulting from the alignment of p-NA crystals dispersed in polymer matrix. The structure-property relationship between crystallization process and SHG activity for POE/p-NA system is discussed.

TL;DR: The approach adopted in the present quantum computational study can be used for similar studies for better description and understanding of the NLO responses of the electron donor-bridge-acceptor systems with π-conjugated bridges.
