Ultrafast structural flattening motion in photoinduced excited state dynamics of a bis(diimine) copper(I) complex.
The ultrafast photoinduced structural change dynamics of a prototypical Cu(I) complex, namely, [Cu(dmp)2](+) (dmp = 2,9-dimethyl-1,10-phenanthroline), is investigated based on the theoretical analysis of static and dynamical calculations at the all-atomic level. This work mainly focuses on the intriguing structural flattening features of [Cu(dmp)2](+) occurring in the metal-to-ligand charge tra...
متن کاملSubstituent effect on the photoinduced structural change of Cu(I) complexes observed by femtosecond emission spectroscopy.
The Cu(I) complexes having phenanthroline derivatives as ligands are known to exhibit photo-induced 'flattening' structural change in the metal-to-ligand charge transfer (MLCT) excited state. Our recent ultrafast spectroscopic studies of [Cu(dmphen)2](+) (dmphen = 2,9-dimethyl-1,10-phenanthroline) showed that the photo-induced structural change predominantly occurs in the S1 state on a subpicos...
متن کاملLong-lived and oxygen-responsive photoluminescence in the solid state of copper(I) complexes bearing fluorinated diphosphine and bipyridine ligands.
Luminescence properties of a family of newly synthesized copper(i) complexes bearing 2,2'-bipyridine derivatives and 1,2-bis[bis(pentafluorophenyl)phosphino]ethane (dfppe), [Cu(diimine)(dfppe)]PF6, were investigated. The quantum yield and the lifetime of the emission of [Cu(6dmbpy)(dfppe)]PF6 (6dmbpy = 6,6'-dimethyl-2,2'-bipyridine) in the solid state under argon (Φ = 9%, τ = 16, 180 μs), which...
متن کاملDissymmetric dinuclear transition metal complexes as dual site catalysts for the polymerization of ethylene
A series of dissymmetric dinuclear complexes were synthesized, as dual site catalysts in ethylene polymerization, by coupling the allylated a-diimine complexes of the metals Ti, Zr, V, Ni and Pd with the ansa-zirconocene complex [C5H4-SiH(Me)-C5H4]ZrCl2 possessing a hydride silane moiety. The different stages of syntheses included the formation of bis(cyclopentadienide)methyl silane which was u...
متن کاملHighly emissive copper(I) complexes bearing diimine and bis(diphenylphosphinomethyl)-2,2-dimethyl-1,3-dioxolane.
A highly emissive copper(I) complex bearing (4R,5R)-(-)-4,5-bis(diphenylphosphinomethyl)-2,2-dimethyl-1,3-dioxolane (diop) and 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (dmpp), [Cu(dmpp)(diop)]PF6 (1·PF6), was newly synthesized. The quantum yield of the luminescence of 1·PF6 in degassed dichloromethane is 0.38, which is one of the highest values among all copper(I) complexes bearing two bid...
