Abstract: Rapid industrialization has led to a steady increase in the demand for organic nonlinear optical (NLO) single crystals for optoelectronic applications. A new organic polymorph of 2-Nitroaniline (P-2NA) single crystal of γ phase has been grown by the slow evaporation method and studied, which appears to be a potential material for NLO applications and an electrode material for energy storage applications. According to the X-ray diffraction investigation, the grown P-2NA crystal belongs to a monoclinic structure with the centrosymmetric P121/n1 space group. The functional groups and vibrational modes present in the crystals were identified using FT-IR analysis. The UV–Vis–NIR analysis was used to obtain the linear optical properties of the crystal. The laser damage threshold was tested and the value of the P-2NA was obtained to be 10.40 GW/cm2. The mechanical and thermal stabilities of the P-2NA crystal were also studied. The grown crystal dielectric measurements and electrical conductivity for various frequencies and temperatures were investigated. From the analysis of the Z -scan method, the P-2NA material has a negative refractive index value of − 2. 6 0 7 × 1 0 − 9 cm2/W that exhibits a self-defocusing nature, a reverse saturable absorption is absorbed from the positive value of nonlinear absorption coefficient (6. 0 2 3 4 × 1 0 − 4 cm/W) and the materials have higher third-order susceptibility (5. 5 4 9 × 1 0 − 6 esu). Moreover, the supercapacitive performance of the P-2NA crystal was confirmed by cyclic voltammetry analysis since a rapid redox reaction took place. These results suggested that it is a suitable candidate for the fabrication of NLO and energy-storing devices. [ABSTRACT FROM AUTHOR]
