“…It is well known that noncentrosymmetric structure facilitates charge transfer. In recent years, the research has been focused on the effect of donor or acceptor substitution of functional groups provides the asymmetric charge distribution in the -electron system and elongation of the conjugation path length for enhancing molecular optical nonlinearities (Singh et al, 2012;Jayarama et al, 2013;Patil et al, 2014). Consequently, the interaction hyperpolarizability, which is an effect of intermolecular interaction on hyperpolarizability, has attracted increasing interest in recent years.…”

Single crystals of (E)-N′-(4-isopropylbenzylidene)isonicotinohydrazide monohydrate (IBIHM) were grown from ethanol by the slow evaporation from solution growth technique at room temperature. The structure was elucidated by single-crystal X-ray diffraction analysis and crystallized in the orthorhombic system with noncentrosymmetric space group P212121. Optical studies reveal that the absorption was minimum in the visible region and the band-gap energy was estimated using the Kubelka–Munk algorithm. The functional groups were identified by Fourier transform infrared spectral analysis. A scanning electron microscopy study revealed the surface morphology of the grown crystal. Investigation of the intermolecular interactions, crystal packing using Hirshfeld surface analysis and single-crystal X-ray diffraction confirm that the close contacts were associated with molecular interactions. Fingerprint plots of Hirshfeld surfaces are used to locate and analyze the percentage of hydrogen-bonding interactions. The second-harmonic generation efficiency of the grown specimen was superior to that of the reference material, potassium dihydrogen phosphate. The grown crystals were further characterized by mass spectrometry and elemental analysis. Theoretical studies using density functional theory (DFT) greatly substantiated the experimental observations. Large first-order molecular hyperpolarizability (β) of about ∼70× was observed for IBIHM. The efficiency of IBIHM in terms of nonlinear optical response was verified and the molecule displayed greater chemical stability and reactivity.

“…Two side of the aromatic rings of the compound consists of strong inter molecular interaction due to electron donor and electron acceptor π-conjugate system [7][8][9]. Due to resilient intermolecular interactions second and third order nonlinearity observed [10][11][12][13][14][15][16]. Also chalcone have medical applications like antimalarial, anti-fungal, anti-cancer, anti-HIV and antioxidants, anti-ulcer, anti-inflammatory, anti-mitotic etc.…”

“…[15][16][17] Dharmaprakash et al have synthesized numerous chalcone derivatives and mainly investigated the crystalline perfection, thirdorder NLO and OL properties. [18][19][20][21][22] Despite these effects, however, the NLO mechanism and excited-state dynamics of these chalcone chromophores remains elusive. 23 Gu et al studied the NLO properties of chalcone derivatives and proposed that their NLO response could be attributed to the multi-photon absorption induced excited-state absorption mechanism (MPA induced ESA).…”
