A green anal. strategy has been developed for the anal. of 10 perfluorinated compounds (PFCs) incorporating supramol. solvent (SUPRAS)-based extraction and ultra-high-performance supercritical fluid chromatog. (UHPSFC)-tandem mass spectrometry. The SUPRAS was prepared through self-assembly of reverse micelles by mixing heptanol, THF, and water at optimized volume ratios. An imidazolium-based germinal dicationic ionic liquid (DIL), 1,1-bis(3-methylimidazolium-1-yl) butylene difluoride ([C₄(MIM)₂]F₂), was dissolved in the make-up solvent of UHPSFC and introduced post-column but before the electrospray ionization source. After chromatog. separation on a Torus DIOL anal. column (100 mm x 2.1 mm, 1.7μm), the PFC analytes associated with the DIL reagent through charge complexation. The formation of pos. charged complexes resulted in improved ionization efficiency and anal. sensitivity. Enhancement in signal intensity by one to two magnitudes was achieved in the pos. ionization mode compared to the neg. ionization mode without using the dicationic ion-pairing reagent. The developed protocol was applied to 32 samples of real textiles and 6 samples of real food packaging materials, which exhibited great potential for the anal. of anionic compounds

Tam, Teck Lip Dexter published the artcileThermoelectric Performances of n-Doped Ladder-Type Conjugated Polymers Using Various Viologen Radical Cations, Quality Control of 47369-00-6, the publication is ACS Applied Polymer Materials (2021), 3(11), 5596-5603, database is CAplus.

Understanding the dopant-polymer interaction is of interest to the conducting polymer research community due to its influence on charge transport properties and also thermoelec. performance. However, studies on such interactions are often complicated by the change in polymer morphol. upon the addition of dopants. Here, we utilized sequential solution doping of a ladder-type poly(benzimidazobenzophenanthrolinedione) (BBL) via viologen radical cation salts. The strong interchain interaction in BBL prevents the infiltration of the viologen radical cations into individual BBL fibrils, thus minimizing the disruption of the polymer morphol. By changing the N-substitution (benzyl or hexyl) and counteranion (chloride or iodide) of the viologen radical cations, the dopant-polymer interaction in such a system was studied. Our results suggest that the anion-π (radical) interaction between the counteranion and BBL (BBL^–) is detrimental to the charge transport properties and thermoelec. performance of this system. This anion-π (radical) interaction between the counteranion and BBL (BBL^–) is governed by the solution state of the viologen radical cation (tightly bound anion or dimerized with loosely bound anion) during the doping process, which is controlled by the bulkiness of the N-substitution and the Lewis basicity of the counteranion. As a result, BBL doped with benzyl viologen monochloride showed the highest conductivities with reasonably high Seebeck coefficients while BBL doped with hexyl viologen monochloride showed inferior conductivities and Seebeck coefficients

Two series of ionic liquid crystals derived from diphenylviologens, I and II, were prepared and their photophys. and electrochem. properties were also investigated. The crystallog. data of two single crystals, I (R = C_nH_2n+1, n = 10) and II-BF₄ (R = C_nH_2n+1, n = 12), showed that a mono- or bilayer-lamellar structure was induced by intermol. H-bonds. All mesophases were identified as smectic A phases by POM textures and powder XRD data. A linear correlation plot (R² = 0.8885) of the d-spacings vs. the calculated effective radius (R_eff) in compounds II was obtained. The aggregation-induced emission (AIE) ranging from ca. 463 to 529 nm observed in compounds II (e.g., X = BF₄, PF₆, RSO₃, OTf and NTf₂) was also anion dependent. Also, compounds II exhibited thermal switching, with an On/Off-emission mode between the Cr and SmA phases. In its cyclic voltammogram, compound I-RSO₃ (R = C_nH_2n+1, n = 12) exhibited two distinct reversible redox couples; in contrast, compound II-RSO₃ (R = C_nH_2n+1, n = 12) formed spike-like voltammetric peak potentials without redox couples.

Kao, Sheng-Yuan published the artcileAn electrochromic device based on all-in-one polymer gel through in-situ thermal polymerization, Recommanded Product: 1,1′-Diphenyl-[4,4′-bipyridine]-1,1′-diium chloride, the publication is Solar Energy Materials & Solar Cells (2016), 145(Part_1), 61-68, database is CAplus.

A self-standing all-in-one electrochromic gel utilizing Ph viologen (PV) and N,N,N’,N’-tetramethyl-1,4-phenylenediamine (TMPD) as the electrochromic materials is prepared by incorporating a thermo-cured cross-linked polymer matrix. The thermal-cured polymer matrix can prevent the agglomeration of PV happening on the electrode surface, resulting in the excellent write-erase ability of the obtained gelated ECD. Moreover, the cross-linker which possesses the long propoxylated arms leads to the easier diffusion for both PV and TMPD in the obtained polymer network. As a result, the obtained ECD exhibits a large transmittance change (ΔT>67% at 620 nm) within a short response time (<3.5 s) under an extremely low driving voltage (0.5 V). Besides, this device remains over 55% of ΔT after 10,000 cycles of switching.

Han, Zhiji published the artcileCO₂ Reduction Selective for C_â‰? Products on Polycrystalline Copper with N-Substituted Pyridinium Additives, Product Details of C22H18Cl2N2, the publication is ACS Central Science (2017), 3(8), 853-859, database is CAplus and MEDLINE.

Electrocatalytic CO₂ reduction to generate multicarbon products is of interest for applications in artificial photosynthetic schemes. This is a particularly attractive goal for CO₂ reduction by Cu electrodes, where a broad range of hydrocarbon products can be generated but where selectivity for C-C coupled products relative to CH₄ and H₂ remains an impediment. Herein the authors report a simple yet highly selective catalytic system for CO₂ reduction to C_â‰? hydrocarbons on a polycrystalline Cu electrode in bicarbonate aqueous solution that uses N-substituted pyridinium additives. Selectivities of 70-80% for C₂ and C₃ products with a hydrocarbon ratio of C_â‰?/CH₄ significantly >100 were observed with several additives. ¹³C-labeling studies verify CO₂ to be the sole C source in the C_â‰? hydrocarbons produced. Upon electroreduction, the N-substituted pyridinium additives lead to film deposition on the Cu electrode, identified in one case as the reductive coupling product of N-arylpyridinium. Product selectivity can also be tuned from C_â‰? species to H₂ (âˆ?0%) while suppressing methane with certain N-heterocyclic additives.

When mech. vibration (56 Hz) of dipyridinium dications I (R = Me, R¹ = cyano, X = Br; R = Ph, R¹ = H, X = Cl; R = Me, R¹ = H, X = Cl), II (n = 2, 3, 4), and III (100 mg each) was conducted with a stainless steel ball (6.0-mm diameter, 890 mg) in a stainless steel twin-shell blender (7.8-mm diameter, 24 mm long) for 30 min at room temperature under strictly anaerobic conditions, the powder surfaces of all I and of II (n = 2) turned deep blue-purple, and nearly isotropic broad single-line ESR spectra were observed in the resulting powders, which can be ascribed to the formation of the corresponding monocation radicals via solid-state single electron transfer (SSET). Facile intermol. SSET also occurred from the monocation radical of I (R = Me, R¹ = H, X = Cl) to I (R = Ph, R¹ = H, X = Cl) and to II (n = 4). The mech. induced SSET reported herein seems to be a general phenomenon with broad implications for many organic compounds with relatively low redox potentials and is of special significance in connection with manufacturing a variety of solid materials in pulverized form in a metallic vessel.

Charged organic adsorbates play an important role in a number of electrochem. reactions, e.g. as additives for metal plating relevant for device fabrication in the semiconductor industry. Fundamental investigations are mandatory in order to acquire profound knowledge of the structural and electronic properties of these layers parallel and perpendicular to the surface, and to finally achieve a deeper mechanistic understanding of the kinetics of involved charge transfer reactions taking place at these complex metal/organic/electrolyte interfaces. A key structural motif of these interfaces consists in ‘paired’ (inorganic)anion/(organic)cation layers that can have an enormous stability even during an ongoing charge transfer reaction. In this contribution we present and discuss a selected case study on the co-adsorption of halide anions and cationic organic mols. that exhibit a pronounced redox activity. It will be demonstrated that their phase behavior at the interface crucially depends on both their particular redox-state and the surface concentration of the halide counter ions. The subtle balance between adsorbate-adsorbate and adsorbate-substrate interaction of the poly-cationic organic layer can be carefully controlled by potential dependent anion adsorption and desorption processes through the organic layer. This process can be followed by in situ high-resolution scanning tunnelling microscopy, while addnl. information about the structural and chem. state of the resp. phase is obtained from in situ X-ray diffraction and ex situ photoelectron spectroscopy.

Kao, Sheng-Yuan published the artcileAchieving a large contrast, low driving voltage, and high stability electrochromic device with a viologen chromophore, Name: 1,1′-Diphenyl-[4,4′-bipyridine]-1,1′-diium chloride, the publication is Journal of Materials Chemistry C: Materials for Optical and Electronic Devices (2015), 3(14), 3266-3272, database is CAplus.

The viologen radical salt (VRS), consisting of Ph viologen (PV) dications and 2,2,6,6-tetramethyl-1-piperidinyloxy derivative (TEMPOD) anions, was successfully synthesized. The VRS was combined with N,N,N’,N’-tetramethyl-p-phenylenediamine (TMPD) to form an electrochromic device (ECD). This ECD offers significant transmittance changes (>60% at both 580 and 620 nm), but only requires 0.4 V for switching, the lowest driving voltage ever reported. Such a low driving voltage further strengthens the energy-saving capability of the ECD. The incorporation of TEMPOD in the ECD greatly improved its write-erase ability while insufficient bleaching was clearly observed within only 5 cycles in the case of its counterpart without adding TEMPOD anions. No significant decay in the transmittance change was noticed in the proposed ECD after subjecting to 100 cycles. Even better cycling stability would be expected if counter anions with multiple TEMPO units were utilized.
