Electric Literature of 19845-69-3, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 19845-69-3, Name is 1,6-Bis(diphenylphosphino)hexane, molecular formula is C30H32P2. In a Article，once mentioned of 19845-69-3
Reaction of (tpyC6H4C=CAu)n {tpyC 6H4C=CH = 4′-(4-ethynylphenyl)-2,2′:6′,2″- terpyridine} with diphosphane ligands Ph2P(CH2) xPPh2 (x = 2 dppe, 3 dppp, 4 dppb, 5 dpppen, 6 dpph) in CH2Cl2 afforded the corresponding dual luminescent binuclear gold(I) complexes [(tpyC6H4C=CAu)2- (mu-dppe)] (1), [(tpyC6H4C=CAu)2(|i-dppp)] (2), [(tpyC6H4C=CAu)2(|i-dppb)] (3), [(tpyC6H4C=CAu)2(mu-dpppen)] (4), [(tpyC6H4C=CAu)2(mu-dpph)] (5). Crystal structural analysis of complexes 1·2CH2Cl2 and 2·2CH2Cl2 show that the terpyridine moieties are free of coordination in these gold(I)-acetylide-phosphane complexes. Spectrophotometric titration between complex 1 and [Eu(tta)3] (Htta = 2-thenoyltrifluoroacetone) or [Yb(hfac)3(H2O) 2] (Hhfac = hexafluoroacetylacetone) gave a 2:1 ratio between Ln(beta-diketonate)3 (Ln = Eu, Yb) units and the complex 1 moiety, indicating the formation of Au2Ln2 complexes. Both the luminescence titrations and the luminescence quantum yields of Au 2Ln2 (Ln = Eu, Yb) solutions show that the energy transfer occurs efficiently from the binuclear gold(I) antennas 1-5 to EuIII and YbIII centers, and all complexes 1-5 are good energy donors for sensitization of visible and NIR luminescence of EuIII and Yb III ions.
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 19845-69-3 is helpful to your research., Electric Literature of 19845-69-3
