Piperonal chalcone derivative incorporating the pyrazolo[3,4-b]pyridine moiety; crystal structure, spectroscopic characterization and quantum chemical investigations

“…In contrast, the NLO properties of organic substances depend on the intermolecular donor–acceptor interaction, delocalized π electron systems, and their ability to crystallize non-symmetrically to the center. 8 Current research trends have been focused on organic materials, mainly those with chromophore groups and widely delocalized π electron structures, since their NLO coefficients are higher than those of inorganic materials.…”

“…Additionally, they are widely used in industrial applications such as second harmonic generation (SHG), optical modulation, optical switching, laser technology, optical data storage, electro-optical switches, optical logic, signal processing, ultra-fast optical communication, and for optical limiting purposes. 2–8…”

“…5,13–15 Several experimental studies have been conducted on the NLO properties of various chalcones, and encouraging results have been reported for future applications such as nonlinear frequency conversion, nonlinear refraction, optical limiters, and SHG (15 times greater than urea). 5,8,16–20…”

“…Additionally, they are widely used in industrial applications such as second harmonic generation (SHG), optical modulation, optical switching, laser technology, optical data storage, electro-optical switches, optical logic, signal processing, ultra-fast optical communication, and for optical limiting purposes. [2][3][4][5][6][7][8] The NLO properties of a material depend on the degree of charge separation (molecular hyperpolarizability) induced by light and the photoinductive changes of the molecular dipole moment. 1,9 Thus, in general, the NLO properties of inorganic substances depend on their constituent ions.…”

Growth, linear- nonlinear optical studies and quantum chemistry formalism on an organic NLO crystal for opto-electronic applications: experimental and theoretical approach

“…Among those, material exhibiting high optical nonlinearity is considered to be a promising aspirant due to its potential usage in nonlinear optical technologies demanding low power laser systems [3,4]. The synthesis and growth of such nonlinear optical materials seems to be a challenge in the fast developing fields of optoelectronics and photonics [5][6][7]. Within the organic category, dinitrobenzoate derivatives play a vital role in biological area due to its anti-creatinine property and these derivatives serves as radiation sensitizers for the treatment of tumour [8].…”
