Synthesis, growth, and characterization of bis (potassium) 2,4-dinitrophenolate monohydrate (BPDNP): a new third harmonic generation material

Novel semi-organic single crystals of bis (potassium) 2,4-dinitrophenolate monohydrate were grown by slow evaporation technique at room temperature. Single-crystal XRD confirms that the crystal belongs to monoclinic system with space group C2/c. H-1 NMR and C-13 NMR studies were conducted for the crystal. In order to know the purity, LC-MS studies were also conducted for the crystal. Functional groups present in the synthesized compound were confirmed by FT-IR analysis. UV-Vis studies show that the crystal has a lower cutoff wave length at 461 nm. Dielectric studies were carried out to study the charge transport mechanism in the crystal. Photoconductivity study exhibits the positive photoconductivity nature of the grown crystal. Nonlinear absorption coefficient (beta), nonlinear refraction (n (2)), and third-order susceptibility (chi ((3))) were also evaluated for the grown crystal.
