Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 7650-91-1, Name is Benzyldiphenylphosphine, SMILES is P(C1=CC=CC=C1)(CC2=CC=CC=C2)C3=CC=CC=C3, belongs to chiral-phosphine-ligands compound. In a document, author is Liu, Chao, introduce the new discover, Application In Synthesis of Benzyldiphenylphosphine.
Chiral Ag-23 nanocluster with open shell electronic structure and helical face-centered cubic framework
We report the synthesis and crystal structure of a nanocluster composed of 23 silver atoms capped by 8 phosphine and 18 phenylethanethiolate ligands. X-ray crystallographic analysis reveals that the kernel of the Ag nanocluster adopts a helical face-centered cubic structure with C-2 symmetry. The thiolate ligands show two binding patterns with the surface Ag atoms: tri- and tetra-podal types. The tetra-coordination mode of thiolate has not been found in previous Ag nanoclusters. No counter ion (e.g., Na+ and NO3-) is found in the single-crystal and the absence of such ions is also confirmed by X-ray photoelectron spectroscopy analysis, indicating electrical neutrality of the nanocluster. Interestingly, the nanocluster has an open shell electronic structure (i.e., 23(Ag 5s(1))-18(SR) = 5e), as confirmed by electron paramagnetic resonance spectroscopy. Time-dependent density functional theory calculations are performed to correlate the structure and optical absorption/emission spectra of the Ag nanocluster.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 7650-91-1 is helpful to your research. Application In Synthesis of Benzyldiphenylphosphine.
