CF3 Substitution of [Cu(P^P)(bpy)][PF6] Complexes: Effects on Photophysical Properties and Light-Emitting Electrochemical Cell Performance

Herein, [Cu(P^P)(N^N)][PF6] complexes (P^P=bis[2-(diphenylphosphino)phenyl]ether (POP) or 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (xantphos); N^N=CF3-substituted 2,2?-bipyridines (6,6?-(CF3)2bpy, 6-CF3bpy, 5,5?-(CF3)2bpy, 4,4?-(CF3)2bpy, 6,6?-Me2-4,4?-(CF3)2bpy)) are reported. The effects of CF3 substitution on their structure as well as their electrochemical and photophysical properties are also presented. The HOMO?LUMO gap was tuned by the N^N ligand; the largest redshift in the metal-to-ligand charge transfer (MLCT) band was for [Cu(P^P){5,5?-(CF3)2bpy}][PF6]. In solution, the compounds are weak yellow to red emitters. The emission properties depend on the substitution pattern, but this cannot be explained by simple electronic arguments. Among powders, [Cu(xantphos){4,4?-(CF3)2bpy}][PF6] has the highest photoluminescence quantum yield (PLQY; 50.3 %) with an emission lifetime of 12 mus. Compared to 298 K solution behavior, excited-state lifetimes became longer in frozen Me-THF (77 K; THF=tetrahydrofuran), thus indicating thermally activated delayed fluorescence (TADF). Time-dependent (TD)-DFT calculations show that the energy gap between the lowest-energy singlet and triplet excited states (0.12?0.20 eV) permits TADF. Light-emitting electrochemical cells (LECs) with [Cu(POP)+(6-CF3bpy)][PF6], [Cu(xantphos)(6-CF3bpy)][PF6], or [Cu(xantphos){6,6?-Me2-4,4?-(CF3)2bpy}][PF6] emit yellow electroluminescence. The LEC with [Cu(xantphos){6,6?-Me2-4,4?-(CF3)2bpy}][PF6] had the fastest turn-on time (8 min), and the LEC with the longest lifetime (t1/2=31 h) contained [Cu(xantphos)(6-CF3bpy)][PF6]; these LECs reached maximum luminances of 131 and 109 cd m?2, respectively.

Silver(I) complexes of bis[2-(diphenylphosphino)phenyl] ether

The reaction of AgOTf in dichloromethane with bis(2-(diphenylphosphino)phenyl) ether (DPEphos) in an equimolar ratio afforded a dinuclear complex [Ag2(kappa2-P,P?-DPEphos)2(mu-OTf)2] (1), whereas the similar reaction in a 1:2 molar ratio resulted in the formation of a bis-chelating complex [Ag(kappa2-P,P?-DPEphos)2][OTf] (2). The silver(I) complex 1 was obtained as a dimer, in which two silver atoms are bridged by two triflate groups to form three adjacent eight-membered spirocyclic rings. The mixed-ligand complex [Ag(kappa2-P,P?-DPEphos)(2,2?-bpy)][OTf] (3) was obtained in the reaction of 1 in dichloromethane with 2,2?-bipyridine. The crystal structures of complexes 1-3 were determined by single crystal X-ray analyses.

Copper photoredox catalysts for polymerization upon near UV or visible light: Structure/reactivity/efficiency relationships and use in LED projector 3D printing resins

Copper complexes (CuCs) bearing pyridine-pyrazole ligands are synthesized and evaluated as new photoredox catalysts/photoinitiators in combination with an iodonium salt (Iod) for the free radical polymerization of (meth)acrylates and the cationic polymerization of epoxides upon visible light exposure using a Light Emitting Diode (LED)@405 nm. The structure/reactivity/efficiency relationships for the copper complexes are studied as well as the chemical mechanisms involved. The different substituents on the pyrazole moiety of the ligand allow tuning of the oxidation potential and the visible light absorbance of the complexes and to optimize the performance of the polymerization photoredox catalysts. The use of a novel additive (CARET) in a three-component system (CuC/Iod/CARET) highly improves the performance. Finally, the high performances of the Cu(i) complexes for the development of new 3D printing resins using an LED projector are demonstrated. Currently, LED projector printing is really advantageous in 3D printing i.e. this technology projects the profile of an entire layer at one time.

Synthesis, structures and photophysical properties of copper(I) 2-(2-benzimidazolyl)-6-methylpyridine complexes with different diphosphine ligands

A series of new Cu(I) 2-(2-benzimidazolyl)-6-methylpyridine (Hbmp) complexes containing five different diphosphine auxiliary ligands have been synthesized and well characterized. It is revealed that all Cu(I) atoms display distorted N2P2tetrahedral geometries with distinct P?Cu?P bond angles regulated by diverse diphosphine ancillary ligands, in which Hbmp serves as a charge-neutral chelating ligand without the deprotonation of the benzimidazolyl-NH while the diphosphine ligand adopts a bridging or chelating coordination mode. It is demonstrated that all these Cu(I) complexes show a relatively weak low-energy absorption in solution and exhibit good luminescence properties in solution and solid states at room temperature, which are more markedly influenced by the P?Cu?P bond angle.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of: (Oxybis(2,1-phenylene))bis(diphenylphosphine), you can also check out more blogs about166330-10-5

Preparation of Tri- and tetrasubstituted allenes via regioselective lateral metalation of benzylic (Trimethylsilyl)alkynes using TMPZnCl·LiCl

The zincation of various 1-(trimethylsilyl)-3-aryl-1-propynes with TMPZnCl·LiCl followed by a Pd-catalyzed coupling with aryl halides provides arylated allenes in 52-92% yield. Subsequent metalation with TMPZnCl·LiCl and cross-coupling with a second different aryl halide provides regioselectively tetrasubstituted allenes in 42-70% yield. This sequence can be performed in a one-pot procedure. DFT calculations and NMR studies support the formation of allenylzinc and propargyllithium intermediates starting from 1-(trimethylsilyl)-3-phenyl-1-propyne.

Cu Photoredox Catalysts Supported by a 4,6-Disubstituted 2,2?-Bipyridine Ligand: Application in Chlorotrifluoromethylation of Alkenes

Interest in base metal catalysis motivates the development of Cu-based photoredox catalysts for organic synthesis. However, only a few Cu catalysts have been applied in photoredox reactions, the majority of which contain one or two 1,10-phenanthroline ligands. Here we design a 4,6-disubstituted 2,2?-bipyridine ligand for Cu. Two heteroleptic [Cu(N^N)(P^P)][PF6] complexes, where N^N stands for the 2,2?-bipyridine ligand and P^P stands for a bisphosphine ligand, have been synthesized and characterized. They exhibit longer excited state lifetimes and higher Cu(I)/Cu(II) potentials compared to the most widely used Cu catalyst, [Cu(dap)2]Cl. The complex with Xantphos as the P^P ligand is an efficient catalyst for chlorotrifluoromethylation of terminal alkenes, especially styrenes, which had been challenging substrates for previously reported photoredox reactions. This chlorotrifluoromethylation method enables the convenient introduction of a trifluoromethyl group into organic molecules under mild conditions, which is important for medicinal chemistry.

Synthesis, characterization, and photophysical properties of heteroleptic copper(I) complexes with functionalized 3-(2′-pyridyl)-1,2,4-triazole chelating ligands

A new series of mononuclear copper(I) complexes (1-9) with functionalized 3-(2′-pyridyl)-1,2,4-triazole chelating ligands, as well as the halide and/or phosphine ancillary ligands, have been synthesized. Complexes 1-9 were fully characterized by elemental analysis, NMR spectroscopy, mass spectroscopy, electronic absorption spectroscopy, fluorescence spectroscopy, cyclic voltammetry, and X-ray crystallography (1-8). They adopt a distorted tetrahedral configuration, and are considerably air-stable in solid state and in solution. All these Cu(I) complexes display a comparatively weak low-energy absorption in CH2Cl2 solution, assigned to charge-transfer transitions with appreciable MLCT character, as supported by TD-DFT studies. Cu(I) halide complexes 1-4 each shows bright solid-state emission at room temperature, although they are nonemissive in fluid solutions, in which the emission markedly depends on the halide and the substituent on the 2-pyridyl ring. Complexes 5-9 bearing 2-pyridyl functionalized 1,2,4-triazole and phosphine exhibit good photoluminescence properties in solution and solid states at ambient temperature, which are well-modulated via the alteration of the auxiliary phosphine ligand and the structural modification of 3-(2′-pyridyl)-1,2,4- triazole. Interestingly, cationic complex 6 and neutral derivative 7 can readily be interconverted through the ring inversion of the 1,2,4-triazolyl regulated by the NH a?” N- transformation.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 166330-10-5, you can also check out more blogs about166330-10-5

Photocatalytic CO2 Reduction Using Cu(I) Photosensitizers with a Fe(II) Catalyst

Photocatalytic systems developed from complexes with only abundant metals, i.e., CuI(dmp)(P)2+ (dmp =2,9-dimethyl-1,10-phenanthroline; P = phosphine ligand) as a redox photosensitizer and FeII(dmp)2(NCS)2 as a catalyst, produced CO as the main product by visible light irradiation. The best photocatalysis was obtained using a CuI complex with a tetradentate dmp ligand tethering two phosphine groups, where the turnover number and quantum yield of CO formation were 273 and 6.7%, respectively.

Photo- and electro-luminescence of three TADF binuclear Cu(i) complexes with functional tetraimine ligands

Three new binuclear cuprous complexes with similar tetraimine ligands [Cu2(pytzph)(POP)2](BF4)2 (1), [Cu2(pytzphcf)(POP)2](BF4)2 (2) and [Cu2(pytzphcz)(POP)2](BF4)2 (3), (pytzph = 6,6?-(1-phenyl-1,2,4-triazole-3,5-diyl)bis(2-methylpyridine), pytzphcf = 6,6?-(1-(4-(trifluoromethyl)phenyl)-1,2,4-triazole-3,5-diyl)bis(2-methylpyridine), pytzphcz = 9-(4-(3,5-bis(6-methylpyridin-2-yl)-1,2,4-triazol-1-yl)phenyl)-carbazole and POP = bis[2-(diphenylphosphine)phenyl]ether), have been synthesized and characterized in order to compare the different effects of substituent groups on the photoluminescence (PL) and electroluminescence (EL) properties. These complexes exhibit highly efficient green thermally activated delayed fluorescence (TADF) with short decay times (5.5-16 mus) and high photoluminescence quantum yields (up to 79%) at room temperature in the solid form. These complexes have essentially identical emission energy. However, the influence of the substituents on the photoluminescence and electroluminescence efficiencies is evident. Complex 3 with the carbazole group shows the highest efficiency in terms of both PL and EL, exhibiting an EQE of 8.3%, a CE of 27.1 cd A-1 and a peak brightness of 2525 cd cm-2 in the solution-processed OLED, while complex 2 with a trifluoromethyl appendage exhibits poorer quantum efficiency than the others.
