IR spectroscopy of two polymorphs of copper(I) thiocyanate and of complexes of copper(I) thiocyanate with thiourea and ethylenethiourea

Syntheses and infrared spectroscopic studies are reported for two different polymorphs of copper(I) thiocyanate and for adducts of copper(I) thiocyanate with thiourea (‘tu’) and ethylenethiourea (‘etu’ = imidazolidine-2-thione; (CH2NH)2CS)). These include the previously reported complex CuSCN/etu (1: 2), which has a trigonal monomeric structure, and CuSCN/etu (1: 1), which has a three-dimensional polymeric structure. A mechanochemical/infrared study of the CuSCN: tu (1: 2) system showed that no 1: 2 complex exists in this case, the product being a mixture of a 1: 3 complex and a novel 1: 0.5 complex. The latter complex was prepared both mechanochemically and from solution, and characterized by infrared and solid-state 65Cu broadline NMR spectroscopy. Diagnostic ligand and metal-ligand bands in the IR and far-IR spectra are assigned for both polymorphs of CuSCN and for all of the complexes studied and are discussed in relation to the structures of the complexes.

Copper(I) coordination polymers with alkanedithiol and -dinitrile bridging ligands

CuI-based coordination polymers with 1,2-ethanedithiol, 3,6-dioxa-1,8-octanedithiol and 3-oxa-1,5-pentanedinitrile as respectively mu-S,S? and mu-N,N? bridging ligands have been prepared by reaction of CuI with the appropriate alkane derivative in acetonitrile. ?2[Cu(HSCH2CH2SH) 2]I (1) contains 44 cationic nets, ? 2[(CuI)2(HSCH2CH2OCH 2CH2OCH2CH2SH)] (2) neutral layers in which stairlike CuI double chains are linked by dithiol spacers. In contrast to these 2D polymers, ?1[CuI(NCCH2CH 2OCH2-CH2CN)] (3) and ? 1[(CuI)4(NCCH2CH2OCH 2CH2CN)2] (4) both contain infinite chains with respectively (CuI)2 rings and distorted (CuI)4 cubes as building units. Solvothermal reaction of CuI with the thiacrown ether 1,4,10-trithia-15-crown-5 (1,4,10TT15C5) in acetonitrile affords the lamellar coordination polymer ?2[(CuI)3(1,4, 10TT15C5)] (7) in which copper atoms of individual CuI double chains are bridged in a mu-S1,S4 manner. The third sulphur atom S10 of the thiacrown ether coordinates a copper(I) atom from a parallel chain to generate a 2D network.

Thiophene-based molecular and polymeric semiconductors for organic field effect transistors and organic thin film transistors

Organic electronics has been a popular field for the last two decades, due to its potential to commercialize cheap-price and large-area flexible electronics. The devices based on organic compounds heavily rely on organic semiconductors (OSs). Primary challenge for materials chemist is the new OSs construction that has ameliorated attainment in organic thin film transistors (OTFTs) and organic field effect transistors (OFETs). The construction of air-stable (stable in air) n-channel OSs (electron-conducting materials) is particularly needed with capability comparable to that of p-channel materials (hole-conducting materials). In the last 10?years, there have been significant advancements in thiophene-based OSs. Thiophene-mediated molecules have a prominent role in the advancement of OSs. The main significance in thiophene-based molecules is their cheap-price (in comparison to silicon), processability at low temperature, structural flexibility, ability to be applied on flexible substrates, and high charge transport characteristics. In this paper, we review the progress in the performance of thiophene-based OSs that has been reported in the last 18?years, with a major emphasis on the last 10?years. This approach provides a crisp introduction to organic devices and catalogs progress toward the fabrication of thiophene containing p, n and ambipolar channel OSs, and discusses their characteristics. Finally, review discusses current challenges and future research directions for thiophene based OSs. This review would be beneficial for further developments in the technological performance. Moreover, this review will serve to accelerate knowledge and lays the foundation for improved applications. Hopefully, this struggle pushes the reader?s mind to consider new perspectives, think differently and forge new connections.

New copper(I) complexes bearing lomefloxacin motif: Spectroscopic properties, in vitro cytotoxicity and interactions with DNA and human serum albumin

In this paper we present lomefloxacin’s (HLm, 2nd generation fluoroquinolone antibiotic agent) organic and inorganic derivatives: aminomethyl(diphenyl)phosphine (PLm), its oxide as well as new copper(I) iodide or copper(I) thiocyanate complexes with PLm and 2,9-dimethyl-1,10-phenanthroline (dmp) or 2,2?-biquinoline (bq) as the auxiliary ligands. The synthesized compounds were fully characterised by NMR, UV?Vis and luminescence spectroscopies. Selected structures were analysed by theoretical DFT (density functional theory) methods. High stability of the complexes in aqueous solutions in the presence of atmosferic oxygen was proven. Cytotoxic activity of all compounds was tested towards three cancer cell lines (CT26 – mouse colon carcinoma, A549 – human lung adenocarcinoma, and MCF7 – human breast adenocarcinoma). All complexes are characterised by cytotoxic activity higher than the activity of the parent drug and its organic derivatives as well as cisplatin. Studied derivatives as well as parent drug do not intercalate to DNA, except Cu(I) complexes with bq ligand. All studied complexes caused single-stranded cleavage of the sugar?phosphate backbone of plasmid DNA. The addition of H2O2 caused distinct changes in the plasmid structure and led to single- and/or double-strain plasmid cleavage. Studied compounds interact with human serum albumin without affecting its secondary structure.

CuSCN modified PEDOT:PSS to improve the efficiency of low temperature processed perovskite solar cells

The energy structure of PEDOT:PSS limits the perovskite solar cell (PSC) performance based on inverted FTO/PEDOT:PSS/perovskite/PCBM structure. Here, inorganic CuSCN is modified on PEDOT:PSS using spin-coating method under low temperature, which is compatible with the low temperature fabrication of PSC. Modification CuSCN guarantees the light harvesting of perovskite layer because of the transparency of CuSCN and good crystalline of perovskite film on CuSCN/PEDOT:PSS substrate. Furthermore, CuSCN effectively changes the energy states of PEDOT:PSS to decrease the energy loss during charge transport, promoting the charge transfer at the same time. Based on the improved charge transport and reduced energy loss, the photovoltaic property of PSC based on CuSCN/PEDOT:PSS reaches the optimized efficiency of 10.9%, much better than the control PEDOT:PSS-based device with 9.1% performance (AM1.5, 1sun).

Ionic liquid doped organic hole transporting material for efficient and stable perovskite solar cells

As a hole transporting material (HTM), N2,N2,N2?,N2?,N7,N7,N7?,N7?-octakis (4-methoxyphenyl) spiro [fluorene-9,9?-xanthene]-2,2?,7,7?-tetraamine (X60) in mesoscopic perovskite solar cells (PSCs) has been widely utilized for substitution of the 2,2?,7,7?-tetrakis (N,N-di-p-methoxyphenylamine)-9,9?-spiro-bi-fluorene (spiro-OMeTAD). In this study, we have introduced an ionic liquid N-butyl-N’-(4-pyridylheptyl) imidazolium bis (trifluoromethane) sulfonamide (BuPyIm-TFSI) as a p-dopant to increase the hole conductivity and stability of the X60 based perovskite solar cells. As a result, based on the different concentrations of BuPyIm-TFSI in mesoscopic PSCs, the optimal condition (4.85 mM) showed the best power conversion efficiency (PCE) of 14.65%, which is extremely higher than the device without BuPyIm-TFSI. Moreover, the device based on X60: BuPyIm-TFSI composite HTM at ambient conditions with humidity of ~40% exhibited good PSCs performance with the long-term stability of 840 h. Hence, the use of BuPyIm-TFSI as a p-dopant for X60 played a significant role in enhancing the electrical properties, stability and efficiency of PSCs.

Silver Bismuth Sulfoiodide Solar Cells: Tuning Optoelectronic Properties by Sulfide Modification for Enhanced Photovoltaic Performance

Silver bismuth iodides (AgaBibIa+3b) are nontoxic and comparatively cheap photovoltaic materials, but their wide bandgaps and downshifted valence band edges limit their performance as light absorbers in solar cells. Herein, a strategy is introduced to tune the optoelectronic properties of AgaBibIa+3b by partial anionic substitution with the sulfide dianion. A consistent narrowing of the bandgap by 0.1 eV and an upshift of the valence band edge by 0.1?0.3 eV upon modification with sulfide are demonstrated for AgBiI4, Ag2BiI5, Ag3BiI6, and AgBi2I7 compositions. Solar cells based on silver bismuth sulfoiodides embedded into a mesoporous TiO2 electron-transporting scaffold, and a poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] hole-transporting layer significantly outperform devices based on sulfide-free materials, mainly due to enhancements in the photocurrent by up to 48%. A power conversion efficiency of 5.44 ¡À 0.07% (Jsc = 14.6 ¡À 0.1 mA cm?2; Voc = 569 ¡À 3 mV; fill factor = 65.7 ¡À 0.3%) under 1 sun irradiation and stability under ambient conditions for over a month are demonstrated. The results reported herein indicate that further improvements should be possible with this new class of photovoltaic materials upon advances in the synthetic procedures and an increase in the level of sulfide anionic substitution.
