Three strongly emissive Cu(I) complexes [Cu(tBupzmpy)(POP)]BF4(1), [Cu(Phpzmpy)(POP)]BF4(2) and [Cu(Adpzmpy)(POP)]BF4(3) (tBupzmpy = 2-(5-(tert-butyl)-1H-pyrazol-3-yl)-6-methylpyridine, Phpzmpy = 2-methyl-6-(5-phenyl-1H-pyrazol-3-yl)pyridine, Adpzmpy = 2-(5-((3R,5R)-adamantan-1-yl)-1H-pyrazol-3-yl)-6-methylpyridine, and POP = bis[2-(diphenylphosphino)phenyl]ether) were synthesized and characterized. These complexes exhibit bright bluish-green photoluminescence in the solid state with quantum yields of 91% (1), 71% (2) and 77% (3) and lifetimes of 13.4 μs (1), 32.9 μs (2) and 34.1 μs (3) at room temperature The results of theor. calculations, coupled with the temperature dependence of the spectroscopic properties and emission decay behaviors, reveal that the title Cu(I) complexes emit efficient thermally activated delayed fluorescence (TADF) from excited states involving metal-to-ligand charge transfer (MLCT) transitions and ligand-to-ligand charge transfer (LLCT) transitions. The emissive-state characteristics and emission properties of the investigated Cu(I) complexes were tuned effectively by changing the steric and electronic structures of the diimine ligands.

Reaction of copper(I) salt with 2, 2′-bipyridine in different solvent produced two Cu4O4-based coordination complexes [Cu4(2,2′-bipyridine)4(OH)4(BF4)2](BF4)2. •2DMF (1) and [Cu4 (2,2′-bipyridine)4(OH)4(BF4)2] (BF4)2 • 2[Cu4(2,2′-bipyridine)4 (OH)4(BF4)](BF4)3 (2). Structural anal. shows that the Cu4O4 cores in 1 are interconnected by four OH- anions in the μ2-O and μ3-O coordination modes and four 2,2′-bipyridine in a bidentate mode to form a ladder-like conformation, while the Cu4O4 cores in 2 are linked by ligands OH- (ladder-like: μ2-O and μ3-O; cage-like: μ3-O) and bipyridine to yield two different conformations, and the Cu atoms also form different kinds of weak Cu … π interactions with the Cu … πcentroid distances of 3.415-3.664 Å in 1, and 3.501-3.667 Å in 2. DFT studies indicate the stability may be 1 > 2, and the HOMOs is collaboratively contributed by the Cu4O4 cores with admixed BF4- character, while the LUMOs is mainly localized on the copper d-orbital with admixed O atoms. In addition, calculation of at. charges by the Mulliken method display that the charges of the central Cu atoms are <+2, and the anion BF4 may be the key to the metal transfers charge to the coordinated atom.

Asym. cyanoborylation of allenes RCH:C:CH2 with cyanamide Ph(Ts)NCN and diborane B2pin2 catalyzed by copper complexes with chiral imidazolidinylidene NHC ligands, (4S,5S)-1,3-(R1R2-Naph)2-4,5-Ph2C3H2N2 (R1R2-Naph = 2-R1-6-R2-1-naphthyl) afforded chiral cyanovinylboronates (S)-RCH(CN)C(Bpin):CH2 with 73-98% yields and 96:4 e.r. The simultaneous incorporation of both a cyano group and a boryl unit into the C:C double bonds of allenes in a regio- and stereoselective fashion is of much interest and importance, but remains a significant challenge. We report herein a copper-catalyzed chemo-, regio-, and enantioselective cyanoborylation of allenes, which afforded a family of valuable enantiopure β-boryl allyl nitriles. The high enantioselectivity was achieved by installing of appropriate substituents at the C2 and C6 positions of the naphthyl groups in our newly synthesized N-heterocyclic carbene (NHC) ligands. The reaction mechanism has been clarified by some stoichiometric reactions and computational studies. This work provides an inspiring example of the development of selective catalytic reactions for the synthesis of functional mols. through fine-tuning the ligands in catalysis.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Copper(I) tetra(acetonitrile) tetrafluoroborate, is researched, Molecular C8H12BCuF4N4, CAS is 15418-29-8, about The [Ag25Cu4H8Br6(CCPh)12(PPh3)12]3+ : Ag13H8 silver hydride core protected by [CuAg3(CCPh)3(PPh3)3]+ motifs.Application In Synthesis of Copper(I) tetra(acetonitrile) tetrafluoroborate.

Copper alkynyl complexes [CuAg3(CCAr)3(PPh3)3]+ (Ar = Ph, p-C6H4Me), in which three Ag(PPh3) units are bound among three CCAr arms of trigonal-planar [Cu(CCAr)3]2-, were selected as a protecting unit to cover the metal core of an atomically precise core-shell-type cluster. First, the formation of the protecting unit through the reaction of Cu(NCMe)4(PF6) with Ag(CCAr) and PPh3 in a 1 : 3 : 3 ratio was confirmed. The reaction gave dimeric [CuAg3(CCAr)3(PPh3)3]22+, in which the two planar [CuAg3(CCAr)3(PPh3)3]+ units were stacked. Next, core-shell-type clusters were synthesized by adding NaBH4 and Et4NX (X = Cl, Br) to a solution similar to that used to prepare the protecting unit. The trigonal-planar protecting units nicely formed core-shell-type Ag nanoclusters formulated as [Ag13H8X6{CuAg3(CCAr)3(PPh3)3}4]3+ (X = Cl, Ar = p-C6H4Me; X = Br, Ar = p-C6H4Me; X = Br, Ar = Ph). Their crystal structures revealed that the four [CuAg3(CCAr)3(PPh3)3]+ units are linked by six halogen ions to form a tetrahedral cage that accommodates a polyhydride-Ag cluster formulated as Ag13H85+. As a concrete proof of the existence of the polyhydride, deuterated analogs Ag13D85+ were synthesized and subsequently characterized by high-resolution electrospray-ionization mass spectrometry measurements.

A diamine ligand having an electron-withdrawing oxadiazole in its mol. structure was designed. With the help from an auxiliary ligand, PPh3, its Cu(I) complex was synthesized and analyzed, including single crystal structure, electronic transitions and photophys. features. A distorted tetrahedral coordination field was adopted by this Cu(I) complex which experienced intense geometric distortion. To limit this excited state geometric distortion and consequently improve its emissive performance, this Cu(I) complex was dispersed and immobilized into a polymer rigid framework through electrospinning method. A detailed anal. on the photophys. parameters of solid sample, solution sample and electrospinning fibrous samples suggested that polymer immobilization was highly effective in limiting excited state geometric distortion. Dopant mols. were dispersed and immobilized in polymer’s rigid and protective microenvironment. In this case, their geometric distortion was effectively limited, showing improved photophys. performance, such as emission blue shift, long-lived emissive center and better photostability.

Author is Goo, Zi Lang; Minami, Katsue; Yoshinari, Nobuto; Konno, Takumi.

The recently-increasing interest in coinage metal clusters stems from their photophys. properties, which are controlled via heterometalation. Herein, the authors report homometallic Ag46IS13 clusters protected by octahedral fac-[Ir(aet)3] (aet = 2-aminoethanethiolate) mols. and their conversion to heterometallic Ag43IM3IS13 (M=Cu, Au) clusters. The reactions of fac-[Ir(aet)3] with Ag+ and penicillamine produced [Ag46S13{Ir(aet)3}14]20+ ([1]20+), where a spherical Ag46IS13 cluster is covered by fac-[Ir(aet)3] octahedra through thiolato bridges. [1]20+ was converted to [Ag43M3S13{Ir(aet)3}14]20+ ([1M]20+) with an Ag43IM3IS13 cluster by treatment with M+, retaining its overall structure. [1]20+ was photoluminescent and had an emission band ∼690 nm that originated from an S-to-Ag charge transfer. While [1Cu]20+ showed an emission band with a slightly higher energy of ∼650 nm and a lower quantum yield, the emission band for [1Au]20+ shifted to a much higher energy of ∼590 nm with an enhanced quantum yield.

Compound: Copper(I) tetra(acetonitrile) tetrafluoroborate, is researched, Molecular C8H12BCuF4N4, CAS is 15418-29-8, about Scrutinizing “”Ligand Bands”” via Polarized Single-Crystal X-ray Absorption Spectra of Copper(I) and Copper(II) Bis-2,2′-bipyridine Species.Computed Properties of C8H12BCuF4N4.

High-energy resolution fluorescence-detected Cu K-edge x-ray absorption spectroscopy (XAS) and single-crystal polarized XAS data are presented toward refining the assignments of bands assigned as excitations from Cu 1s to ligand-localized MOs. These were previously dubbed XAS-metal-ligand charge transfer (XAS-MLCT) bands. Data are presented for [Cu(xbpy)2]n+ complexes (xbpy = 2,2′-bipyridine (1n+), 4,4′-bisamino-2,2′-bipyridine (2n+), and 4,4′-dimethoxy-2,2′-bipyridine (3n+); n = 1 and 2). Dipolar dependencies of these XAS-MLCT bands in both Cu1+ and Cu2+ species lead to reassignment of these features as owing their intensities primarily to Cu 1s → Cu 4p excitations. The transition densities are Cu-localized, highlighting that XAS-MLCT features in Cu XAS spectra are not charge transfer transitions but rather quasi-at. transitions. Although scrutiny of the acceptor orbitals supports assignment as Cu 1s → ligand π* transitions, it ultimately appears that while the ligand orbital energetics govern the positions of these bands the intensity is conferred through a small degree of metal 4p mixing into otherwise ligand-dominated acceptor MOs. Single-crystal polarized Cu K-edge x-ray absorption spectra are presented toward refining an assignment of transitions that involve ligand-dominated MOs.
