“…The second harmonic generation (SHG) efficiency of these compounds is due to the strong intermolecular electron-donor-acceptor interactions, which may also enhance the non-linear optical (NLO) properties. With the possibility of developing low-cost, large-area and flexible electronic devices, -conjugated systems have been studied extensively for their optoelectronic properties (Chandra Shekhara Shetty et al, 2016, 2017.…”

“…The D-A conjugation and the linkage spacer will influence the distributions of the molecular orbitals and the energy gap [51] of the concerned molecules. The strong π-electron delocalization [52] which is beneficial for the charge transfer and the extension of the conjugation length [53] can both increase the nonlinear optical properties. Similar to the situation for the TPA, azobenzene [54,55], thiophene [56,57] and styryl units [53,58] etc.…”

“…In table 6, the results of 4M1PMS and 4BPMS were compared with organic/inorganic/thin films based materials. It is noted that the value of c 3 ( ) is reasonably larger than that for small conjugation based organic molecular system [50,66,67] but two-fold magnitude order greater than those for inorganic materials [68,69]. Furthermore, results are comparable with organic/ organometallic based thin films and dyes materials [70][71][72][73].…”

In the present work, growth of single crystals of chalcone derivatives {4-[(1E)-3-(4-methylphenyl)-3oxoprop-1-en-1-yl]phenyl 4-methylbenzene-1-sulfonate} (4M1PMS) and {4-[(1E)-3-(4-bromophenyl)-3-oxoprop-1-en-1-yl]phenyl4-methylbenzene-1-sulfonate} (4BPMS), at room temperature is reported. The spectroscopic techniques are used to identify the presence of functional groups in the materials. The single-crystal XRD and powder XRD analysis reveals that 4M1PMS belongs to noncentrosymmetric (P2 2 2 1 1 1 ) and 4BPMS belongs to centrosymmetric P n 2 1 ( ) / crystalline system. The molecular structures exhibit C-HKO and π...π intermolecular interactions. From UV/VIS/NIR spectroscopic studies, it is found that both samples have bathochromic shifts in linear absorbance (cut-off region) spectra. The broad emission region involved in several sharp emission peaks in blue region, exhibits a blue light emission property, as observed from photoluminescence study, in both the samples. The thermal stability of the materials were studied by TGA/DTA techniques and crystals were thermally stable until the melting point. In NLO study, 4M1PMS crystal has shown SHG efficiency 2.2 times that of KDP crystal. In addition, electronic contribution in hyperpolarizability (first order and second order) tensors of both the compounds were computed theoretically by M06-2X functional at DFT level. The open/closed aperture Z-scan technique were performed to evaluate third order nonlinear optical materials by measuring experimental parameters such as nonlinear absorption/refraction and calculate second-order hyperpolarizability with corresponding third-order nonlinear optical susceptibility c 3 ( ) ( ) of 4M1PMS and 4BPMS. The surface damage threshold studies of 4M1PMS and 4BPMS were performed by Q-switched Nd:YAG laser at 532 nm.
