On February 29, 2020, Karthick, S.; Thirupugalmani, K.; Krishnakumar, M.; Kannan, V.; Vinitha, G.; Brahadeeswaran, S. published an article.Formula: C7H4ClNO4 The title of the article was Synthesis, structural, dielectric, laser damage threshold, third order nonlinear optical and quantum chemical investigations on a novel organic crystalline material: Pyrrolidin-1-ium 2-chloro-4-nitrobenzoate 2-chloro-4-nitrobenzoic acid for opto-electronic applications. And the article contained the following:
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 anal. revealed that PCNCN belonged to monoclinic crystal system with a centrosym. space group of P21/c. The morphol. of the as grown PCNCN crystal compared well with that obtained by theor. generated morphol. The mol. vibrations of PCNCN were analyzed through Fourier transform IR 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 dielec. properties such as dielec. constant, dielec. 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 chem. investigations were performed using B3LYP/6-311++G(d, p) basis set. The experimental process involved the reaction of 2-Chloro-4-nitrobenzoic acid(cas: 99-60-5).Formula: C7H4ClNO4
