Abstract

A novel organic nonlinear optical crystals 4-N, N-dimethylamino- 4′-N′-methyl-stilbazolium 3, 4 dimethoxy sulfonate (DOST) with high-quality were grown by spontaneous nucleation method. The crystal quality, defect types and growth mechanism...

Molecular Structure Design, Crystal Growth, and Characterization of New Types of Organic Nonlinear Optical Chalcone Crystals

“…This clearly shows that the change in the position of the methoxy group leads to a significant change in the contact distribution in the crystal structure. As shown in Figure 7, the HOMO−LUMO gap of the molecular orbitals of the two crystals, which is valuable for the internal charge transfer, optical polarizability, and NLO activity analysis of the molecular crystals, 45,46 is calculated using the Gaussian 09W program combined with the 6-311G basis set of B3LYP. The HOMO−LUMO diagram was drawn by Multiwfn 47 and VMD, 48 and the molecular orbital diagrams of the two crystals were found to be similar.…”

Synthesis and characterization of a new isoxazolone-based nonlinear optical crystal: MPMOI

“…[14][15][16][17][18][19] In the past few decades, many organic nonlinear optical crystals have been discovered. [20][21][22][23][24][25][26][27][28] The selection of acceptors in the D-π-A structures is crucial in order to design organic nonlinear optical crystals with large nonlinear optical susceptibilities. Isoxazolone is one of the strong acceptors, with the same electron donor CH 3 S-in chloroform solution, λ max,isoxazolone (408 nm) 29 > λ max,Pyridinium (320 nm), 30 indicating that the simple asymmetric structure of isoxazolone also has strong electron absorption capacity.…”

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

“…In recent years, with the continuous development of nonlinear optical technology, organic nonlinear optical (NLO) materials have attracted great interest due to their excellent optical frequency amplification, optical modulation, optical switching, and optical storage functions. , Therefore, organic nonlinear materials with high second-order nonlinear coefficients and ultrafast response have become a research hotspot. − Among them, organic single-molecule nonlinear optical materials with easy polarization, easy molding, and large nonlinear optical coefficient have good application prospects in the production of optical modulation devices, optical switching devices, and terahertz generation and detection. − …”
