“…1) groups pull the electron density away from the C6 and C2 carbon atoms, resulting in the signal shift towards higher ppm. [33][34][35] The chemical shift noticed at 181.87 ppm can be attributed to C1 and C5 carbon atoms present in the KMB crystal structure.…”

Potassium bis(2-methyllactato)borate hemihydrate (KMB) was grown by a solvent evaporation technique. Crystal structural analysis revealed that the potassium cation was pseudo-octahedrally coordinated by five O atoms from four bis(2-methyllactato)borate (MB) ligands and half-occupied water. The sharp peaks in the powder x-ray diffraction (PXRD) pattern confirmed the perfect crystalline nature of the KMB. Transparency was observed in the range from 215 nm to 1100 nm, and the bandgap of KMB was determined to be 2.15 eV. The molecular structure of KMB was established by interpreting the functional group vibrations through vibrational spectroscopy. The molecular structure was further confirmed by the nuclear magnetic resonance (NMR) spectral technique. The peak followed by valley nature observed is due to the self-focusing behavior of KMB. The minimum transmission near the focus in the open aperture curve is attributed to the reverse saturation absorption nature of KMB. The third-order susceptibility (v (3) ) of KMB is estimated to be 4.17694 9 10 À5 esu. These results suggest that KMB can be used in optical sensors as well as other photonic and optoelectronic applications.

“…This anticipation motivates the considerable search among organic crystals for improved NLO materials. When compared to inorganic materials, NLO chromophores are implanted in organic materials in a noncentrosymmetric way, revealing excellent nonlinear activity [3][4][5][6]. Tosylic acid, also known as p-toluene sulfonic acid, is an organic acid available in solid phase.…”

Piperazine (bis) p-toluenesulfonate (PPTSA), an organic single crystal was synthesized and grown at environmental temperature by slow evaporation process using methanol as the solvent. The grown PPTSA crystal is from the triclinic system and belongs to the space group P1-. Powder X-ray diffraction was performed to ensure lattice parameters. Analysis and confirmation of functional groups and bonds were carried out through FT-IR spectral study. The optical characteristics were investigated using the UV-Vis spectrum such as the optical absorption, cut-off wavelength were calculated. The photoluminescence investigation was conducted to assess the luminous characteristics of grown crystal. The calculated NLO parameters like β, n2, and χ(3) were found to be 0.0495×10-4 (cm/W), 8.705×10-10 (cm2/W), 5.316×10-7 (esu) and Optical Limiting threshold value was found to be 3.074×10-3 (Wcm-2). Antibacterial studies were carried out to investigate the biological significance against selected foodborne germs.
