It is reported that a novel third order organic nonlinear optical material namely, Pyrrolidin-1-ium 2-chloro-4-nitrobenzoate 2-chloro-4-nitrobenzoic acid (PCNCN) has been synthesized and grown by isothermal solvent evaporation solution growth technique. Single crystal X-ray diffraction analysis revealed that PCNCN belonged to monoclinic crystal system with a centrosymmetric space group of P21/c. The morphology of the as grown PCNCN crystal compared well with that obtained by theoretically generated morphology. The molecular vibrations of PCNCN were analyzed through Fourier transform infrared and NMR spectrum analyses. Optical properties such as transmittance, photoluminescence, and laser damage threshold were studied. The thermal stability of PCNCN was measured through TG-DTA measurement. The dielectric properties such as dielectric constant, dielectric loss, ac conductivity and activation energy of PCNCN single crystal were studied as a function of frequency at different temperatures. The PCNCN single crystals were further characterized for their third order nonlinear optical properties such as nonlinear absorption coefficient, nonlinear refractive index and optical limiting behavior using continuous wave Nd: YAG laser. The quantum chemical investigations were performed using B3LYP/6-311++G(d, p) basis set. © 2019 Elsevier Ltd

A new molecular adduct namely, 4-(dimethylamino)benzaldehyde 4-nitrophenol (4DMAB4NP), has been synthesized through crystal engineering route by reacting 4-(dimethylamino)benzaldehyde and 4-nitrophenol in equimolar ratio. This hydrogen bonded material is found to have crystallized with centrosymmetric space group of P21/c at room temperature (RT) and making it appropriate for third order nonlinear optical (TONLO) applications. The different kinds of functional groups existing in the 4DMAB4NP were recorded and assigned through FTIR and NMR spectral studies. Thermal behavior of 4DMAB4NP was analyzed through TGA and DTA analyses. Its solubility in toluene solvent was measured to obtain high quality single crystals. The 4DMAB4NP single crystals were characterized for their laser damage threshold, TONLO properties and optical limiting behavior. Further, the dielectric behavior of 4DMAB4NP single crystal were also investigated as a function of temperature (313–343 K). In addition, density functional studies of 4DMAB4NP molecule in gaseous phase were accomplished at the B3LYP/6–311++G (d, p) basis function. Finally, 3-D Hirshfeld surface maps and the 2-D fingerprint diagram were generated for the title molecule by using crystal explorer 3.1 program. © 2018 Elsevier B.V.
