Usage

General Description

Cyclohexylamine hydrobromide is a chemical compound composed of cyclohexylamine, a six-membered cyclic amine, and hydrogen bromide. It is commonly used as a precursor in the synthesis of pharmaceuticals, agrochemicals, and rubber chemicals. Cyclohexylamine hydrobromide is a white crystalline solid that is soluble in water and alcohol. It is known for its strong odor and is classified as a corrosive substance. Cyclohexylamine hydrobromide is also used in organic synthesis and as a corrosion inhibitor in metal treatments. Additionally, it is used as a stabilizer in the production of rubber and as a catalyst in polymerization reactions.

Control of the white-light emission in the mixed two-dimensional hybrid perovskites (C6H11NH3)2[PbBr4?xIx]

The control of the composition of mixed organic-inorganic hybrid perovskites by solid-state alloying is a very efficient tool to tune the band gap of the material, leading to enhanced optical performances. At this end, we have elaborated a series of mixed-halide two-dimensional hybrid perovskites (C6H11NH3)2[PbBr4?xIx], with 0 ≤ x ≤ 4, for which we studied the composition-dependence of the structural parameters and their effect on the white-light luminescence properties at room temperature. The structural analysis revealed the existence of a composition-induced structural phase transition occurring in the range 2 a change between Cmc21and Pbca space groups. The optical properties, investigated using optical absorption and photoluminescence measurements, have shown that bromine (Br) to iodine (I) halogen ion substitution redshifts the excitonic optical absorption band, as a result of the hybridization of the valence band structure, built from np orbitals of Br and/or I halogens and 6s orbitals of lead. When iodine was predominant (x > 2), the photoluminescence spectra showed a sharp peak with a relatively small Stokes shift (less than 0.2 eV) attributed to free or bound excitons emissions. In contrast, when the bromide is majority (x a broadband white-light emission with a very large Stokes shift (between 1.2 eV and 0.3 eV), attributed to self-trapped excitons activated by a strong structural distortion of the inorganic sheets. Confronting optical and structural data highlighted the effect of the structure in monitoring the optical properties, since the intensity of the white-light emission increases with the bromine content and was found to excellently correlate with the change of the angular distortion of inorganic octahedra PbX6(X = I/Br).

OPTICALLY ACTIVE TRIORGANOSILYL ESTERS OF PHOSPHORUS. SYNTHESIS AND STRUCTURE

We report this synthesis of the first optically active silyl esters of phosphorus having two centres of chirality : one on silicon and the other on phosphorus.Compounds are obtained of general formula : t-BuPhP(X)YSiαNpPhMe X,Y=O, O(1); S, O(2); Se, O(3); S, S(4); doublet, O(5) including 1 and 3 with optical activity located on Si, 2 and 5 with the activity on Si or P and on both these centres, 4 only racemic.Absolute configurations are determined. 31P and 29Si NMR spectra of these models and their trimethylsilyl analogues are reported.The triorganosilyl group is always preferentially bound to phosphorus through oxygen atom.Surprisingly, diastereotopic NMR chemical shifts exclude the fast 1,3 migration in esters 1 and 4. 29Si NMR spectra correspond to a tetracoordinate silicon atom.

KINETICS OF THE REACTIONS OF 2-HALOGENOPYRIDINIUM SALTS WITH PRIMARY AND SECONDARY AMINES IN ACETONITRILE

The kinetics of the reactions of 2-halogeno-N-alkylpyridinium salts with primary and secondary aliphatic amines in acetonitrile at 25 deg C were investigated.The reactions obey second-order relationships.In the reaction of 2-bromo-N-ethylpyridinium bromide with aliphatic amines the effect of electronic and steric factors on the reactivity of the amines was examined.
