A novel nonlinear optical material, (2E)-1-(1-benzofuran-2-yl)-3-(2-bromophenyl) prop-2-en-1-one monohydrate, is synthesized and crystals are grown at ambient temperature using solution growth method. Spectroscopy techniques such as FT-IR, FT-Raman and 1H NMR are used to confirm the presence of functional groups in the grown crystals. These crystals are crystallized in non-centrosym. orthorhombic structure with a space group P212121 and the powder second harmonic generation (SHG) test shows that the SHG efficiency of these crystals are 2.03 times that of KDP. UV-Vis-NIR studies of these crystal shows maximum optical transparency in the complete visible and near IR spectral region. The TGA/DTA anal. reveals that the material manifests good thermal stability (280.8 °C) as well. The nature of mol. interactions and their quant. role towards the crystal packing is being studied using Hirshfeld surface and 2-D fingerprint anal. The advantages of these crystals lie mainly in the ease of growing crystals, low cutoff wavelength (486 nm), and large SHG efficiency with good thermal stability and this makes the material promising for competent frequency doubling of laser.

《Triphenylamine-based conjugated microporous polymers as dye adsorbents and supercapacitors》 was written by Kotp, Mohammed G.; Sharma, Santosh U.; Lee, Jyh-Tsung; El-Mahdy, Ahmed F. M.; Kuo, Shiao-Wei. Safety of Tris(4-bromophenyl)amineThis research focused ontriphenylamine microporous polymer supercapacitor dye adsorption water treatment. The article conveys some information:

Conjugated microporous polymers CMPs have unique position among porous materials thus they are studied widely. Realistically, triphenylamine (TPA) derivatives generally possess high aromaticity, redox capabilities, high charge motilities, and outstanding electronic features, therefore designing CMPs based on TPA derivatives could result in fantastic properties. We performed one-pot coupling and polycondensation of a boronated triphenylamine derivative (TPA-3Bor) with bromobenzene (Bz-4Br) and bromopyrene (Py-4Br) derivatives to obtain two new TPA-based conjugated microporous polymers (TPA-Bz and TPA-Py CMPs, resp.). The successful synthesis of two TPA CMPs and their features were examined via Fourier transform IR (FTIR) and 13C solid state NMR spectroscopies. These two CMPs displayed attractive adsorptive properties toward the small dye mol. rhodamine B (RhB) from an aqueous solution Outstanding adsorption performance, rapid kinetics, and good reusability suggest that our CMPs could function as effective adsorbents for RhB and, perhaps, other pollutants from wastewater. Moreover, our TPA-based CMPs displayed effective and stable performance when introduced as electrodes for supercapacitors, with capacitances as high as 78 F g-1 at a c.d. of 1 A g-1 as well as high stability. This study emphasizes the importance of conjugation and planarity in the future design of such materials.

The article contains the following contents:

Uveal melanoma (UM) represents an aggressive type of cancer and currently, there is no effective treatment for this metastatic disease. In the last years, histone deacetylase inhibitors (HDACIs) have been studied as a possible therapeutic treatment for UM, alone or in association with other chemotherapeutic agents. Here we synthesized a series of new HDACIs based on the SAHA scaffold bearing an (arylidene)aminoxy moiety. Their HDAC inhibitory activity was evaluated on isolated human HDAC1, 3, 6, and 8 by fluorometric assay and their binding mode in the catalytic site of HDACs was studied by mol. docking. The most promising hit was the quinoline derivative , a nanomolar inhibitor of HDAC6, which exhibited a good antiproliferative effect on UM cell lines at micromolar concentration and a capability to modify the mRNA levels of HDAC target genes similar to that of SAHA.
