Second harmonic generation in pyrazoline derivatives of dibenzylideneacetones and chalcone: A combined experimental and theoretical approach

In this work, we investigate theoretically and experimentally second harmonic generation (SHG) in three pyrazoline compounds, being two derivatives of dibenzylideneacetone (DBA) (C23H20N2 and C25H24N2O2) and one derivative of chalcone (C21H18N2). The compounds were synthesized after two steps employing a Claisen-Schmidt condensation followed by an addition-elimination reaction with phenylhydrazine. All compounds were characterized using NMR, FT-IR, UV-Vis, and XRD. We calculated the first-order hyperpolarizabilities of these molecules using program packages based on the time-dependent Hartree-Fock (TDHF) and density functional theory (DFT). SHG was characterized by Kurtz and Perry's powder method. We observed that these organic crystals present SHG efficiencies up to 5 times larger than the KDP, and we associated these values to their molecular structure and crystalline arrangements. The values obtained experimentally and theoretically evidence that these compounds have good potential for application in electronic devices based on second-order nonlinear responses.

BLUE LIGHT BLOCKLING SYSTEM CONTAINING PYRAZOLINE OR/AND BENZOIC ACID COMPOUNDS

The present invention relates to an blue light blocking system characterized in that the blue light blocking agents possess the structure of a pyrazoline of the formula (I) or/and a phenylacrylic acid of the formula (II). The compounds of formula (I) or / and formula (II) fully cover the range of short-wavelength blue light to protect eyes; it can also selectively absorb long-wavelength blue light, so that the transmitted light can provide a particularly good visual experience to humans. The invention is applicable to products such as optical films, optical lenses, goggles, skin care, lighting devices, paints, adhesives, or panels. These products have a light-colored appearance and the penetrating light provides an excellent visual experience for humans.

Photophysical and charge transport properties of pyrazolines

Pyrazoline, an intense green emitting molecule both in solution and solid state, with extended π-conjugation has been synthesized via simple two-step reactions in high yields. Having the electron rich pyrazoline moiety with good redox behavior, pyrazoline
