Optimization of Spatial Arrangement and Optical Nonlinearity of Chalcone Crystals by Halogen Substituted Donor Groups

“…As a result, the four crystals have high thermal stability, among which the highest ECDAN is about 210 °C, and the melting points of the other three crystals are also above 190 °C. Compared with other chalcone derivatives, it has higher thermal stability. − …”

A comprehensive study on the photophysical and non-linear optical properties of thienyl-chalcone derivatives

“…3A25D2 and 3A25D4 have the same order of magnitude of the CW laser NLO parameters with 2,3,4-trimethoxy-4′-nitrochalcone ( 2,3,4TMNC ), 81 4-bromothiophenyl chalcone ( 2AT4B ), 82 and 4,5′-dibromothiophenyl chalcone ( B5B2SC ). 83 To appraise the contribution of third-order optical non-linearity per molecule, the molecular non-linear property is defined as the cubic hyperpolarizability ( γ ), which is related to the third-order susceptibility and given by eqn (A.1). The γ (− ω ; ω , ω , − ω ) is determined in ∼10 −34 and ∼10 −26 esu in fs pulsed and CW domain, respectively.…”

A Quantum Chemical Screening of Two Imidazole-Chalcone Hybrid Ligands and Their Pd, Pt and Zn Complexes for Charge Transport and Nonlinear Optical (NLO) Properties: A DFT Study

“…Chalcone derivatives have extensively been used in optoelectronics as photorefractive polymers, nonlinear optical (NLO) materials, chromophore sensors, fluorescent probes for the determination of metal ions and sensing of DNA, and in the study of photo-alignment layers of liquid crystal displays [1] [2] [3]. As a matter of fact, these derivatives are one of the most interesting groups of materials for NLO applications because, apart from exhibiting high NLO coefficients, they are well-known for their good crystallizability into non-centrosymmetric structures with excellent second harmonic generation (SHG) conversion efficiency [1] [4] [5]. Additionally, they possess a good optical limiting behavior when in contact with nanosecond laser pulses at Nd-YAG laser wavelengths (1064 nm) [6].…”

“…Additionally, they possess a good optical limiting behavior when in contact with nanosecond laser pulses at Nd-YAG laser wavelengths (1064 nm) [6]. It must also be noted that in recent times, organic materials exhibiting NLO properties have intensely been investigated in comparison with traditional inorganic nonlinear crystals because of their many superior properties such as: ultrafast response times, lower dielectric constants, high internal quantum efficiency, high damage threshold, flexible design and low driving voltage which contributes to an efficient energy usage, cognizance of the growing demand for energy, hence impacting immensely the energy budgets of countries [5] [7] [8]. Given that chalcones bear a very good synthon, a variety of novel heterocycles with good pharmaceutical and even NLO profiles dyes have been designed [9].…”
