Stretchable and luminescent networks from copper(I)-coordinated main-chain thioether polymers

Emissive organometallic polymers integrated with the properties of conventional polymers have attracted increasing attention from researchers. Copper (I)-thioether (Cu(I)-thioether) complexes of small molecule has been extensively reported, which is in sharply contrast with much less investigated Cu(I)-thioether polymers. In this work, Cu(I)-thioether coordination structure has been successfully combined with polymer ligands to form emissive polymer networks. The resulted hybrid networks overcame many challenges in the Cu(I)-thioether small compounds. The as-prepared Cu(I)-thioether networks exhibited much improved thermal stability (degradation temperature: 220 C) compared with Cu(I)-thioether molecular clusters. Besides, the Cu(I)-thioether networks can be processed into uniform free-standing film with excellent stretchability (breaking strain up to 200%) which cannot be realized in the Cu(I)-thioether small molecular system. Finally, the luminescent property of copper-thiother was inherited in the polymer networks and emissive polymer films with good transparency, excellent thermal stability and high stretchability. Interestingly, the dynamic coordination between thioether and copper (I) enabled the self-healing ability of the polymer films. The damaged emissive and stretchable films were able to be autonomous self-healed under ambient conditions. This work sheds lights on the design and fabrication of Cu(I)-thioether materials for advanced applications.

Transformation of inorganic sulfur into organic sulfur: A novel photoluminescent 3-D polymeric complex involving ligands in situ formation

The reaction of CuSCN with acetonitrile and methanol under solvothermal conditions yielded a novel 3-D polymeric photoluminescent complex containing dodecanuclear copper(I) clusters with methyl mercaptide. The synthesis involves in situ generation of ligands, which provides a model reaction to simulate the transformation of inorganic sulfur into organic sulfur under geothermic conditions.

Synthesis, characterization, crystal structures and photophysical properties of copper(I) complexes containing 1,1?-bis(diphenylphosphino) ferrocene (B-dppf) in doubly-bridged mode

Five copper(I) complexes having general formula [Cu2(mu-X) 2(kappa2-P,P-B-dppf)2] (X = Cl(1), Br(2), I(3), CN(4), and SCN(5)) were prepared starting with CuX and B-dppf in 1:1 molar ratio in DCM-MeOH (50:50 V/V) at room temperature. The complexes have been characterized by elemental analyses, IR, 1H NMR, 31P NMR and electronic spectral studies. Molecular structures for 1, 2 and 4 were determined crystallographically. Complexes 1, 2 and 4 exist as centrosymmetric dimers in which the two copper atoms are bonded to two bridging B-dppf ligands and two bridging (pseudo-)halide groups in a mu-eta1 bonding mode to generate nearly planar Cu2(mu-eta1-X)2 framework. Both bridging B-dppf ligands are arranged in antiperiplanar staggered conformation in 1 and 2 (mean value 56.40-56.76), and twisted from the eclipsed conformation (mean value 78.19) in 4. The Phi angle value in 4 is relatively larger as compared to 1 and 2. This seems to indicate that the molecular core [Cu2(mu-eta1-X)2] in 4 is a sterically demanding system that forces the B-dppf ligand to adopt a relatively strained conformation in comparison to less strained system in 1 and 2. All the complexes exhibit moderately strong luminescence properties in the solution state at ambient temperature.

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 1111-67-7 is helpful to your research. Reference of 1111-67-7

Structural features of di(1-adamantyl)benzylphosphane complexes of Cu(I) and Ag(I)

The sterically bulky di(1-adamantyl)benzylphosphane (L) reacts with the copper(I) compounds, CuX (X = Cl, Br, I and SCN), in a 1:1 ratio to give the salts CuXL. Single crystal X-ray structures for X = Cl, Br and SCN, show that the complexes exist as dimeric species of the type [Cu2X2L2] with the X groups bridging to give each copper a distorted trigonal-planar coordination geometry with a ?PX2? donor site. When [Cu(CH3CN)4]BF4reacts with L in a 1:2 ratio, the two-coordinated complex [CuL2]BF4was formed which has a P?Cu?P angle of 169.46(6), reflecting the influence of the adamantyl groups. The silver(I) 1:2 compound, [AgClL2], has a ?ClP2? donor set with a distorted P?Ag?P bond angle of about 149.02(5). The reduced coordination numbers, irregular structures and distortions of selected angles are a result of the steric bulk (large cone angle) of L. Some of these structural features may also assist in understanding why Pd(0) complexes of L are effective catalysts for the Sonogashira coupling reactions of arylchlorides and alkynes.

A mild copper-catalyzed aerobic oxidative thiocyanation of arylboronic acids with TMSNCS

A facile and efficient transformation of arylboronic acids to their corresponding aryl thiocyanates has been successfully developed. Based on the CuCl-catalyzed oxidative cross-coupling reaction between arylboronic acids and trimethylsilylisothiocyanate (TMSNCS) under oxygen atmosphere, the transformation can be readily conducted at ambient temperature. The newly-developed protocol provided a competitive synthetic approach to aryl thiocyanates that can tolerate a broad range of reactive functional groups and/or strong electron-withdrawing groups.

Copper(I) pseudohalide coordination polymers containing macrocyclic methylcycloarsoxane (CH3AsO)n (n = 4, 5) or 1,7-dithia-18-crown-6 bridging units

Treatment of an acetonitrile solution of CuCN with methylcycloarsoxane (CH3AsO)n at 110C affords the coordination polymer ?3[CuCN{cyclo-(CH3AsO)4}] (1), in which infinite CuCN zigzag chains are linked by mu-As1,As 3 cyclotetramers (CH3AsO)4 into an open 3-D framework. Under similar solvothermal conditions, reaction of CuSCN with (CH3AsO)n in the presence of KSCN leads to metal-mediated ring expansion of the cycloarsoxane to yield the complex ? 1[{K[cyclo-(CH3AsO)5]2}Cu(NCS) 2] (2). This contains discrete [Cu(NCS-kappaN)2{cyclo- (CH3AsO)5kappaAs}2]- anions that bridge kappa10O coordinated potassium cations into infinite chains. In contrast, the structure directing role of the [K(1,7DT18C6) 2]+ sandwich building units for the solvothermal product ?3[{K(1,7DT18C6)2}Cu6(CN) 7] (3) (1,7DT18C6 = 1,7-dithia-18-crown-6) leads to formation of an open ?3[{Cu6(CN)7} -] framework. Individual [K(1,7DT18C6)2]+ moieties bridge Cu Atoms in a mu-S1,S7 mode and are encapsulated within the large [Cu26(CN)28]2- cages of the cyanocuprate(I) network.

Improving the efficiency and stability of inverted perovskite solar cells by CuSCN-doped PEDOT:PSS

Hole transport layer (HTL) is important in inverted perovskite solar cells (PSCs) to facilitate the hole extraction and suppress the charge recombination for high device performance. Based on the widely used HTL material of poly(ethylenedioxythiophene) (PEDOT):poly(styrenesulfonate) (PSS), we proposed a new HTL modification method using the widely available copper(I) thiocyanate (CuSCN); the doping of CuSCN NH3 [aq] in PEDOT:PSS followed by low-temperature annealing results in reduced energy barrier, improved charge extraction efficiency and increased the mean size of perovskite crystal of the PEDOT:PSS-CuSCN HTL-based inverted PSCs. Significantly improved device performance was observed with open current voltage over 1.0 V and power conversion efficiency (PCE) up to 15.3%, which is 16% higher in PCE than that of the PEDOT:PSS-based PSCs. More impressively, with a lower acidity than PEDOT:PSS, the PEDOT:PSS-CuSCN HTL enables excellent long-term stability of the inverted PSCs, exhibiting almost doubly improved device stability at the same storage condition. Thus, the successful application of CuSCN doping in PEDOT:PSS HTLs should provide a novel approach for the development of high-performance HTLs for highly efficient and stable PSCs.
