We investigated the structural, thermal, linear, and nonlinear optical properties of a newly grown anthracene-based chalcone single crystal, DA-ANC. The crystal was synthesized by a condensation reaction and grown through the evaporation of a solution. Various characterization techniques were used, including XRD, NMR, FT-IR, UV-Vis-NIR spectroscopy, and computational DFT studies. The crystal exhibited strong nonlinear optical properties, suggesting its potential for NLO applications.
We report the structural, thermal, linear and nonlinear optical (NLO) properties of a newly grown anthracene based chalcone single crystal, (2 E )-1-(anthracen-9-yl)-3-[4-(dimethylamino)phenyl]prop-2-en-1one (abbreviated as DA-ANC ). The chalcone was synthesized by Claisen-Schmidt condensation reaction and the single crystals were grown by slow evaporation of solution growth technique. Single-crystal XRD, NMR ( 1 H & 13 C), FT-IR, UV-Vis-NIR spectroscopies, TG/DTA, and computational DFT studies were performed to characterize the crystals. The intermolecular interactions were described by Hirshfeld surface analysis (HSA). The third-order NLO properties of DA-ANC were studied by Z-scan technique using CW-DPSS laser at 532 nm. Open aperture Z-scan exhibits strong two-photon assisted reverse saturation absorption (RSA) with two-photon absorption (TPA) coefficient ( ,B) 6.9 x 10 -5 cmW -1 . Closed aperture Z-scan reveals the negative nonlinear refraction arising due to self-defocusing effect with nonlinear refractive index ( n 2 ) coefficient -1.31 x 10 -8 cm 2 W -1 . The optical limiting behavior based on TPA was performed and limiting-threshold was evaluated to be 6.47 kJ cm -2 . The obtained one-photon and twophoton figures of merit satisfied the conditions of all-optical switching. The results show that DA-ANC can be a potential candidate for NLO applications.
