Hashimoto, Hideki published the artcileCharacteristics of the terahertz radiation from single crystals of N-substituted 2-methyl-4-nitroaniline, Recommanded Product: N-Benzyl-2-methyl-4-nitroaniline, the publication is Journal of Physics: Condensed Matter (2001), 13(23), L529-L537, database is CAplus.

Terahertz (THz) radiation was generated via optical rectification from organic single crystals, i.e. N-substituted (N-benzyl, N-diphenylmethyl, and N-2-naphthylmethyl) derivatives of 2-methyl-4-nitroaniline (MNA), and it was detected by means of the electrooptic sampling method. The intensity and the spectrum of the THz radiation were compared with those of ZnTe and DAST (N,N-dimethylamino-N’-methylstilbazolium p-toluenesulfonate) crystals. The integrated intensity of the THz radiation from the N-benzyl-MNA crystal was two thirds of that for the ZnTe crystal, the best-known practical THz emitter, and was as intense as that for the DAST crystal, the best organic THz emitter ever studied. The spectrum of the ZnTe crystal extended to 3 THz, while that of the N-benzyl MNA and DAST crystals dropped off around 2.5 THz. The THz radiation intensities from all of the organic crystals were compared quant., on the basis of the consideration of mol. arrangements in the crystals. It was suggested that the absorption due to low-frequency phonon modes affected both the intensity and the spectral band shape of the THz radiation.

Organic materials with a high second-order optical nonlinearity have an important application for the next generation of computing, telecommunications, and other industries. Because of a high electro-optic coefficient and low dielec. constant, N-benzyl-2-methyl-4-nitroaniline (BNA) single crystals have been grown and their optical properties have been extensively studied. In this Letter, a poled BNA thin film material was prepared through simultaneous vacuum evaporation and laser-assisted elec. poling. The linear electro-optic coefficients of BNA were measured by a Young’s two-slit interference electro-optic measurement method. The dependence of the resulting electro-optic properties on optical power was explored. Enhancement induced by laser illumination was demonstrated. The BNA thin film can exhibit an r₃₃ value comparable to that of BNA single crystals.

Improvements in electro-optical responses of LC devices by doping organic N-benzyl-2- methyl-4-nitroaniline (BNA) and Morpholinium 2-chloro-4-nitrobenzoate (M2C4N) in nematic liquid crystals (LCs) have been reported in this study. BNA and M2C4N-doped LC cells have the fall time that is fivefold and threefold faster than the pristine LC cell, resp. The superior performance in fall time of BNA-doped LC cell is attributed to the significant decrements in the rotational viscosity and threshold voltage by 44% and 25%, resp., and a strong addnl. restoring force resulted from the spontaneous polarization elec. field of BNA. On the other hand, the dielec. anisotropy (¦¤¦Å) of LC mixture is increased by 16% and 6%, resp., with M2C4N and BNA dopants. M2C4N dopant induces a large dielec. anisotropy, because the phenylamine/hydroxyl in M2C4N induces a strong intermol. interaction with LCs. Furthermore, BNA dopant causes a strong absorbance near the wavelength of 400 nm that filters the blue light. The results indicate that M2C4N doping can be used to develop a high ¦¤¦Å of LC mixture, and BNA doping is appropriate to fabricate a fast response and blue-light filtering LC device. D. Functional Theory calculation also confirms that BNA and M2C4N increase the dipole moment, polarization anisotropy, and hence ¦¤¦Å of LC mixture

Selvaraj, Pravinraj published the artcileElectro-optical effects of organic N-benzyl-2-methyl-4-nitroaniline dispersion in nematic liquid crystals, Computed Properties of 201157-13-3, the publication is Scientific Reports (2020), 10(1), 14273, database is CAplus and MEDLINE.

The dispersion of organic N-benzyl-2-methyl-4-nitroaniline (BNA) in nematic liquid crystals (LCs) is studied. BNA doping decreases the threshold voltage of cell because of the reduced splay elastic constant and increased dielec. anisotropy of the LC mixture When operated in the high voltage difference condition, the BNA-doped LC cell has a fall time that is five times faster than that of the pure one because of the decrements in the threshold voltage of the cell and rotational viscosity of the LC mixture The addnl. restoring force induced by the BNA’s spontaneous polarization elec. field (SPEF) also assists to decrease the fall time of the LC cell. The decreased viscosity can be deduced from the decrements in phase transition temperature and associated order parameter of the LC mixture D. functional theory calculation demonstrates that the BNA dopant strengthens the absorbance for blue light, enhances the mol. interaction energy and dipole moment, decreases the mol. energy gap, and thus increases the permittivity of the LC mixture The calculation also shows that the increased dipole moment, polarizability, and polarizability anisotropy increase the dielec. anisotropy of the LC mixture, which agrees with the exptl. results well. BNA doping has a promising application to the fields of LC devices and displays.

Hsu, Che Ju published the artcileSuperior improvement in dynamic response of liquid crystal lens using organic and inorganic nanocomposite, Application In Synthesis of 201157-13-3, the publication is Scientific Reports (2021), 11(1), 17349, database is CAplus and MEDLINE.

In this study, the response time of a 4 mm-aperture hole-patterned liquid crystal (HLC) lens has been significantly improved with doping of N-benzyl-2-methyl-4-nitroaniline (BNA) and rutile titanium dioxide nanoparticle (TiO₂ NP) nanocomposite. The proposed HLC lens provides the focus and defocus times that are 8.5x and 14x faster than the pristine HLC lens, resp. Meanwhile, the focus and defocus times of the proposed HLC lens reach the order of millisecond. Result shows that the synergistic effect of BNA and TiO₂ NP induces a 78% decrement in the viscosity of pristine LC mixture that significantly shortens the focus and defocus times of HLC lens. The remarkable decrement in viscosity is mainly attributed to spontaneous polarization elec. fields from the permanent dipole moments of the additives. Besides, the strengthened elec. field surrounding TiO2 NP assists in decreasing the focus time of HLC lens. The focus and defocus times of HLC lens are related to the wavefront (or phase profile) bending speed. The time-dependent phase profiles of the HLC lenses with various viscosities are calculated This result shows the decrease in wavefront bending time is not simply proportional to viscosity decrement. Furthermore, the proposed HLC lens emerges a larger tunable focus capability within smaller voltage interval than the pristine HLC lens.

Generation of terahertz radiation by optical rectification of intense near-IR laser pulses in N-benzyl-2-methyl-4-nitroaniline (BNA) is investigated in detail by carrying out a complete characterization of the terahertz radiation. We studied the scaling of THz yield with pump pulse repetition rate and fluence which enabled us to predict the optimal operating conditions for BNA crystals at room temperature for 800 nm pump wavelength. Furthermore, recording the transmitted laser spectrum allowed us to calculate the nonlinear refractive index of BNA at 800 nm.

We performed the direct measurement of second harmonic generation and sum frequency generation phase-matching directions in the organic N-benzyl-2-methyl-4-nitroaniline crystal over its visible and near-IR transparency range. The fit of these data allowed us to refine the Sellmeier equations of the three principal refractive indexes in this range. With these equations, we improved the calculated tuning curves of terahertz emission from a phase-matched difference frequency process. We also determined the absolute magnitude of the d₂₄ nonlinear coefficient
