Abstract

Third-order nonlinear optical material 4-[(1E)-3-(3,4-dimethoxyphenyl)-3-oxoprop-1-en-1-yl]phenyl 4-methylbenzene-1-sulfonate (DMPMS) is crystallized by slow solvent evaporation technique. The crystal has inversion symmetry and belongs to monoclinic system with P2 1∕c space group. The C–H⋯O/C–H⋯π intermolecular interactions will be large complementarity for molecular density/crystal packing. A comprehensive investigation for absorbance and emission properties has been performed. Thermal stability is up to 258 °C without any weight loss and calculated value of laser damage threshold is ≈ 12 GW/cm2. The DMPMS shows low dielectric constant value, about 4.42 at 1 MHz and electronic polarizability values in the order of 10−23 cm3. Furthermore, theoretical calculation has been performed using B3LYP and M06-2X functional. The static first-order hyperpolarizability parameter is 55 (B3LYP) and 34 (M06-2X) times that of urea. The total contribution of second-order hyperpolarizability is − 37.9 ×10−40esu (in B3LYP functional) and − 25.77 ×10−40esu (in M06-2X functional), respectively. Here, two-photon absorption mechanism is responsible for nonlinear absorption and co-efficient is found to be 28.3 × 10−12 m/W. In optical limiting study, limiting threshold is found to be 65 μJ. The real and imaginary third-order nonlinear optical susceptibility is of the order 10−12esu.
