Dendritic (phosphine)gold(I) thiolate complexes: assessment of the molecular size through PGSE NMR studies.
The reactions of the tetraphosphine ligand DAB-G0-(PPh2)4 (DAB = 1,4-diaminobutane; G0 = Generation 0) or the octaphosphine ligand DAB-G1-(PPh2)8 (G1 = Generation 1) with the gold precursor [AuCl(tht)] (tht =tetrahydrothiophene) and the corresponding 4-substituted benzenethiolate lead to the (phosphine)gold(I) thiolate complexes [Au4(S-C6H4-X)4[(DAB-G0-(PPh2)4]] (X = F (11), MeO (12), Me (13) a...
متن کاملInvestigation of the surface chemistry of phosphine-stabilized ruthenium nanoparticles--an advanced solid-state NMR study.
(31)P-(13)C REDOR NMR measurements allowed a reasonable approximation of distances between stabilizing ligands and carbon monoxide (CO) molecules on the surface of phosphine-stabilized ruthenium nanoparticles (RuNPs). The studied systems are RuNPs in the size range of 1-2 nm stabilized with 1,3,5-triaza-7-phosphaadamantane (PTA) or triphenylphosphine (PPh3) and exposed to a CO atmosphere. This ...
متن کامل15N and 31P NMR Studies of Cyano[(Trialkyl/Triaryl)Phosphine]Gold(I) Complexes R3PAu13C15N
been studied for R=Me, Et, i-Pr, and Ph. The reactions are studied by 15N and 31p NMR spectroscopy. Two 31p NMR resonances were observed for R3PAuCN and (R3P)2Au+ species. However, for the 15N NMR, only averaged resonances were observed for R3PAuC15N and Au(C15N)2" species except for Et3PAuC15N, where two resonances were detected.The R3PAu13C15N complexes have also been prepared where R= Me, Et...
متن کامل31 P NMR Evidence for Peroxide Intermediates in Lipid Emulsion Photooxidations: Phosphine Substituent Effects in Trapping.
Intralipid is a lipid emulsion used in photodynamic therapy (PDT) for its light scattering and tissue-simulating properties. The purpose of this study is to determine whether or not Intralipid undergoes photooxidation, and we have carried out an Intralipid peroxide trapping study using a series of phosphines [2'-dicyclohexylphosphino-2,6-dimethoxy-1,1'-biphenyl-3-sulfonate, 3-(diphenylphosphino...
متن کاملAdsorption of Phosphine on a BN Nanosurface
Electrical sensitivity of a Boron Nitride Nano Sheet (BNNS) to phosphine (PH3) molecule is studied using Density Functional Theory (DFT) calculations at the B3LYP/6-31G(d) level of theory. The adsorption energy (Ead) of phosphine on the surface of the pristine Nanosheet is about -678.96×1019eV. Pristine BNNS is a suitable adsorbent for phosphine and can be u...
