Copper-catalyzed direct trifluoromethylthiolation of indoles by: Tert -butyl 2-((trifluoromethyl)sulfonyl)hydrazine-1-carboxylate

In this study, we developed the first copper-catalyzed direct trifluoromethylthiolation of indoles using TfNHNHBoc as a trifluoromethylthiolation reagent. Due to the cheap and readily accessible reagents, as well as its mild reaction conditions and good atom economy, this method is as an alternative and practical strategy for trifluoromethylthiolation of indoles.

Synthesis, structures, luminescence and terahertz time-domain spectroscopy of nine Cu(I) complexes with P^P ligands and 1,10-phenanthroline derivatives

Nine new copper(I) complexes bearing 1,3-bis(diphenylphosphino)propane (dppp) and 4,7-diphenyl-1,10-phenanthroline (batho) or 2,9-dimethyl-1,10-phenanthroline (neo) have been synthesized and characterized. Single crystal X-ray diffraction analysis reveals that complexes 1?4 and 6?9 are mononuclear with similar structures, while complex 5 is a binuclear structure. They display absorption around 280 nm and 410 nm, and the intensive emission in the range of 520?620 nm in the solid state occurring with lifetimes on the mus timescale indicates phosphorescence. Our TD-DFT calculations show that emission from the lowest excited triplet state T1 is of 3MLCT nature. This study manifests that these simple and long-lifetime Cu(I) systems may exhibit a similar, but more complex excited state behavior than the systems previously appreciated.

Inorganic Hole Transporting Materials for Stable and High Efficiency Perovskite Solar Cells

Organic-inorganic hybrid perovskite solar cells (PSCs) have received considerable attentions due to their low cost, easy fabrication, and high power conversion efficiency (PCE), which achieved a certified PCE of 22.7%. To date, most of high efficiency PSCs were fabricated based on organic hole transporting materials (HTMs) such as molecular spiro-MeOTAD or polymeric PTAA. However, poor stability of PSCs limits its large scale commercial application because of use of additives like tert-butylpyridine (t-BP) and lithium salt. Moreover, relatively low-temperature degradation of organic HTMs is responsible for poor thermal stability of PSCs. Consequently, HTM play a crucial role in realization of efficient and stable PSCs. In order to improve the stability of PCSs, various inorganic HTMs have been developed and applied into PSCs. Recently, the devices based on CuSCN and Cu:NiOx HTMs have demonstrated PCEs over 20%, which is comparable to PCEs of devices based on organic HTMs. Most importantly, stability of PCSs are much improved by the inorganic HTM, which indicates clearly that inorganic HTMs are promising alternative to organic HTMs. Herein, we review recent progress on application of inorganic HTMs in PSCs. We highlight the importance of systematic engineering for each layer and respective interface in the whole device for further improvement of PCE and stability.

In situ synthesis and characterization of Cu2O nanowire networks from CuSCN films

Cuprous oxide (Cu2O) nanowire films were in situ grown from pre-deposited cuprous thiocyanate (CuSCN) films which acted as sacrificial precursors. The synthesis was processed in air from NaOH solution, providing an appealing alternative to nanowire-based porous films. Plausible solid-liquid interface reactions were described. Structural analysis showed that Cu 2O nanowires were p-type polycrystalline semiconductor, with high aspect ratio of 10-30 nm in diameter and more than 1 um in length, and they were found to be interlaced with each other in the formation of interpenetrating networks within the Cu2O film which possessed large-area uniformity. It is noteworthy that the nanowire-based films actually are porous films embedded with various interwire spaces and cavities. Photoelectrochemical measurements revealed that a Cu2O film with thickness of 500-1000 nm generated zero-bias photocurrent of approximately 1.5 muA cm-2. The present synthesis is facile and low-cost, and is expected to be suitable for mass production of large-area semiconductor films under ambient condition.

Photovoltage study of charge injection from dye molecules into transparent hole and electron conductors

The investigation of transient and spectral photovoltage (PV) for charge injection from a dye [Ru(dcbpyH2)2(NCS)2] into transparent hole (CuSCN, CuI, CuAlO2) and electron (TiO2, SnO2:F) conductors was discussed. Depending on the transparent hole or electron conductor and on the mechanism of charge separation, the PV signal rises to a maximum within 10 ns to 10 mus. It was shown that the efficiency of hole and electron injection was of the same order while the effective lifetimes of injected charge vary between several mus and 1 ms for the samples used. It was shown that a 1000 W Xe-lamp with a quartz monochromator provided light in the range of 0.4 to 4.5 eV for PV spectra.

An eco-friendly and inexpensive solvent for solution processable CuSCN as a hole transporting layer in organic solar cells

During past few years, significant research on solution-processable deposition of copper(I)thiocyanate (CuSCN) as an efficient hole transporting layer (HTL) for excitonic solar cells have been successfully reported. Surprisingly, till now only two solvents diisopropyl sulfide and diethyl sulfide are known which have been used for CuSCN film deposition as a HTL for device fabrication. Here, we have used eco-friendly and inexpensive solvent dimethyl sulfoxide (DMSO) for solution processed thin film deposition of CuSCN for organic solar cells. The photovoltaic devices were fabricated using two different donor polymers PCDTBT and PTB7 blended with PC71BM as an acceptor material with device structure of ITO/CuSCN/active layer/Al. The power conversion efficiency (PCE) based on CuSCN using DMSO as a deposition solvent have been achieved up to 4.20% and 3.64% respectively, with relative higher fill factor (FF) as compared to previously reported values in literature. The resultant HTLs were characterized by UV?vis?NIR spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM) and atomic force microscope (AFM) for better understanding.

Compositionally tunable Cu2ZnSn(S1-xSe x)4 nanocrystals: Probing the effect of Se-inclusion in mixed chalcogenide thin films

Nanocrystals of multicomponent chalcogenides, such as Cu 2ZnSnS4 (CZTS), are potential building blocks for low-cost thin-film photovoltaics (PVs). CZTS PV devices with modest efficiencies have been realized through postdeposition annealing at high temperatures in Se vapor. However, little is known about the precise role of Se in the CZTS system. We report the direct solution-phase synthesis and characterization of Cu 2ZnSn(S1-xSex)4 nanocrystals (0 ? x ? 1) with the aim of probing the role of Se incorporation into CZTS. Our results indicate that increasing the amount of Se increases the lattice parameters, slightly decreases the band gap, and most importantly increases the electrical conductivity of the nanocrystals without a need for annealing.

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.
