Popis: Single crystals of copper (II) complex of P-Toluene sulfonic acid (PTSC) suitable for photonic applications were grown by slow evaporation technique. Single-crystal X-ray diffraction analysis (SXRD) shows that PTSC crystallizes in monoclinic system with a centrosymmetric space group (P21/c). The presence of red hallows and blue bumps in the shape index of the Hirshfeld surface confirms the NLO activity of the material. Fourier transform infrared spectroscopy vibrational analysis inferred the functional groups present in the synthesized PTSC. The synthesized material has good mechanical properties, and tight atomic packaging with six water molecules reveals its possible utilization in device fabrication applications. The dielectric constant was found to be high due to the inclusion of Cu2+ in the crystal lattice. Linear optical parameters such as bandgap energy, refractive index, extinction coefficient, optical conductivity, electrical conductivity, optical electronegativity, and Urbach energy are calculated from Ultraviolet Visible (UV–Vis) spectral analysis which depicts that the grown PTSC has high optical activity and can be used in the photonic application. The violet and green emission nature of PTSC was examined through Photoluminescence emission studies. The intensity-dependent third-order non-linear optical absorption property of the title material was studied using Z-scan analysis and PTSC exhibits two-photon absorption-induced optical limiting action. The non-linear optical (NLO) behavior of PTSC suggests the possible use in laser-driven applications as it can effectively control the laser to safe level.
