General Description

Bis(4-bromophenyl)dimethylsilane is a chemical compound with the molecular formula C14H16Br2Si. It is a colorless liquid that is used as a reagent in organic synthesis, particularly in the production of specialty polymers and silicone compounds. bis(4-broMophenyl)diMethylsilane is important in the development of advanced materials, such as electronic devices, due to its ability to form strong covalent bonds and provide thermal stability. Additionally, it has been used in the manufacturing of pharmaceuticals and agrochemicals. However, it is important to handle this chemical with care, as it is hazardous if ingested, inhaled, or absorbed through the skin, and can cause irritation to the eyes and respiratory system.

Diphenylsilane-containing linear and rigid whole aromatic poly(azomethine)s. Structural and physical characterization

Six new whole aromatic poly(azomethine)s with different rigidity were prepared from three diamines and two dialdehydes, all of them containing a diphenylsilane moiety as a central structural element. Two amines containing biphenyl moieties were obtained for the first time. Thus, the synthesized polymers contain two silicon atoms in the repeat unit, where methyl and/or phenyl groups bonded to them, complete the tetra-valence of the heteroatom. The new materials were structurally characterized by means of FT-IR, solid NMR and elemental analysis. Solubility was tested in several organic solvents at room temperature and 40 °C and the inherent viscosity was determined. GPC analysis showed oligomeric chains of five repetitive units for the tested samples. Additionally, thermal behavior was studied by TGA and DSC analysis, by evidencing materials highly stable and rigid. Band gaps values ranging between 2.71 and 3.14 eV were obtained from UV/Vis and DRS analysis. The spin-coating technique was used to prepare films from soluble samples in NMP and their thicknesses were determined by the ellipsometric method. From these samples, and using AFM and four-point techniques, the effect of the annealing time on the roughness and conductivity of the films was studied. In accordance with the appropriate thermal and conductivity properties of the new silylated materials (which has a whole aromatic structure), could be proposed as an alternative for applications in the optoelectronics field.

A Highly Stable Triazole-Functionalized Metal–Organic Framework Integrated with Exposed Metal Sites for Selective CO2 Capture and Conversion

Synthesis and characterization of di-, tri- and tetraboronic acids based on phenyl- and thienylsilane cores

The synthesis of a series of di- tri- and tetraboronic acids based on respective phenyl- and thienylsilane cores is described. The optimal protocols involved lithiation of respective arylsilane precursors using either deprotonative lithiation or halogen/lithium exchange with n-BuLi followed by treatment of resultant intermediates with B(Oi-Pr)3 and subsequent hydrolysis, which afforded final products in good yields. X-ray crystal structures of selected diboronic derivatives were determined showing that hydrogen-bonding interactions of B(OH)2 groups are the main factor governing the supramolecular assembly.
