Two donor-acceptor-donor (D-A-D) type low-bandgap small mols., M1 and M2, with bis(2-thienyl)-N-alkylpyrrole (TPT) as the donor and thieno[3,4-b]thiadiazole (TT) as the acceptor were designed and synthesized. The absorption, transmission, electrochem., thermal and film properties were studied. The compounds showed panchromatic absorption in the spectral range of 300-1000 nm. They exhibited semi-transparent property in the visible region (400-700 nm). Small mol. photodetectors (SMPDs) based on M1 and M2 were fabricated and studied. For the SMPD with BCP as the hole blocking layer (HBL), a detectivity of 5.0 × 10¹¹ Jones at 800 nm at -0.1 V was obtained, which is among the highest detectivities reported for NIR SMPDs. With a sufficiently thin Ag electrode, visibly transparent PDs with an average transmittance of 45% in the visible region were obtained for the 1st time. The transparent PDs exhibited fairly constant and high detectivity of (1-10) × 10¹¹ Jones over λ = 300-900 nm. Side chains of the compounds exhibited a great influence on the device performance, which could be assigned to their film absorption coefficient, mol. packing and active layer morphol.

Negishi, Eiichi published the artcileCyclization reactions of ω-tosyloxy-1-alkynyl- and ω-tosyloxy-1-alkenylborates and their ω-halo analogs, Name: (4-Bromobut-1-yn-1-yl)trimethylsilane, the publication is Heteroatom Chemistry (1992), 3(3), 293-302, database is CAplus.

The reaction of trialkylboranes with ω-tosyloxy-1-lithio-1-alkynes can induce transfer of an alkyl group from the boron atom to the alkynyl carbon atom with concomitant formation of four- through six-membered carbocycles via intramol. displacement of the ω-tosyloxy group. Thus, reacting LiCCCH₂CMe₂(CH₂)₃OSO₂C₆H₄Me-4 with tricyclopentylborane gave a mixture of (E)- and (Z)-cyclopentylmethylene-3,3-dimethylcyclohexane. The stereoselectivity of the reaction, however, is low (anti/syn≃1.6-1.7). The corresponding reaction of ω-halo- or ω-tosyloxy-1-alkenylborates also gives exocyclic alkenes via 1,2-migration-cyclization followed by dehydroboration. In the cases of cyclopropanation, cyclopropylcarbinyl-to-homopropargyl rearrangement rather than dehydroboration takes place. Diphenylzirconocene reacts similarly with 6-lithio-5-hexynyl tosylate to give phenylmethylenecyclopentane in 45% yield. On the other hand, attempts to induce a similar migration with Ph derivatives of Y, V, Cr, and Mn have led to < 5-10% yields of the same cyclization product.

Jones, Seamus D. published the artcileDesign of Polymeric Zwitterionic Solid Electrolytes with Superionic Lithium Transport, Application In Synthesis of 55788-44-8, the publication is ACS Central Science (2022), 8(2), 169-175, database is CAplus and MEDLINE.

Progress toward durable and energy-dense lithium-ion batteries has been hindered by instabilities at electrolyte-electrode interfaces, leading to poor cycling stability, and by safety concerns associated with energy-dense lithium metal anodes. Solid polymeric electrolytes (SPEs) can help mitigate these issues; however, the SPE conductivity is limited by sluggish polymer segmental dynamics. We overcome this limitation via zwitterionic SPEs that self-assemble into superionically conductive domains, permitting decoupling of ion motion and polymer segmental rearrangement. Although crystalline domains are conventionally detrimental to ion conduction in SPEs, we demonstrate that semicrystalline polymer electrolytes with labile ion-ion interactions and tailored ion sizes exhibit excellent lithium conductivity (1.6 mS/cm) and selectivity (t₊ ≈ 0.6-0.8). This new design paradigm for SPEs allows for simultaneous optimization of previously orthogonal properties, including conductivity, Li selectivity, mechanics, and processability.

Ryden, Andreas published the artcileSynthesis and tentative identification of novel polybrominated diphenyl ether metabolites in human blood, Name: Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide, the publication is Chemosphere (2012), 88(10), 1227-1234, database is CAplus and MEDLINE.

Hydroxylated polybrominated di-Ph ethers (OH-PDBEs) are exogenous, bioactive compounds that originate, to a large extent, from anthropogenic activities, although they are also naturally produced in the environment. In the present study nine new authentic OH-PBDE reference standards and their corresponding Me ether derivatives (MeO-PBDEs) were synthesized and characterized by NMR spectroscopy and mass spectrometry. Seven of the authentic reference standards prepared were thereafter tentatively identified in a pooled human blood sample. The tentatively identified OH-PBDEs were 3-hydroxy-2,2′,4,4′,6-pentabromodiphenyl ether, 3′-hydroxy-2,2′,4,4′,6-pentabromodiphenyl ether, 3-hydroxy-2,2′,4,4′,5-pentabromodiphenyl ether, 3-hydroxy-2,2′,4,4′,5,6′-hexabromodiphenyl ether, 3′-hydroxy-2,2′,4,4′,5,6′-hexabromodiphenyl ether, 3-hydroxy-2,2′,4,4′,5,5′-hexabromodiphenyl ether and 4-hydroxy-2,2′,3,4′,5,5′,6-heptabromodiphenyl ether. An addnl. seven OH-PBDEs were tentatively identified in the pooled human blood sample, of which one OH-PBDE, 4′-hydroxy-2,2′,4,5,5′-pentabromodiphenyl ether, has not been identified in human blood before. The identification was performed using gas chromatog.-mass spectrometry (GC-MS) recording the bromine ions m/z 79, 81. The tentative identification was supported by the peaks relative retention times (RRTs) compared to authentic references on two GC columns of different polarities for the hexa-, and heptabrominated OH-PBDEs, and three different GC columns for the pentabrominated OH-PBDEs. The OH-PBDE congeners most likely originate from human metabolism of a flame retardant, i.e. polybrominated di-Ph ethers (PBDEs), due to the relatively high concentrations of PBDEs in the same human blood sample and the fact that these PBDEs could form the tentatively identified OH-PBDEs via metabolic direct hydroxylation or via 1,2-shift.

Deyab, M. A. published the artcileFour novel imidazolium-derived ionic liquids: Synthesis and anti-corrosion characteristics, Category: bromides-buliding-blocks, the publication is Journal of Molecular Liquids (2022), 118984, database is CAplus.

This paper described the corrosion inhibiting action of four new imidazolium-derived ionic liquids (ILs) I [X = H, Me, Cl, NO₂]. Elements anal., IR, TGA, ¹H-¹³C NMR, XRD and HSQC-NMR were used to confirm the mol. formula of ILs. The corrosion suppressive effectiveness was calculated using loss of mass and electrochem. experiments and ranged from 53 to 96%. Their adsorption on a steel substrate was precisely characterized using the Langmuir isotherm. Gibbs free energies vary from – 35.24 kJ mol^-1 to – 41.82 kJ mol^-1, indicating that ILs were adsorbing via physi-chemisorption scenario. SEM/EDX and FTIR were used to validate the process of adsorption of ionic liquids

Deyab, M. A. published the artcileTheoretical and experimental investigation of four ionic liquids for their ability to prevent carbon steel corrosion in 1 M HCl, Recommanded Product: 1-Bromooctane, the publication is Journal of Molecular Liquids (2022), 118414, database is CAplus.

The inhibitory mechanism of four ionic liquids (ILs) generated from imidazolium is reported in this study. The goal of the research was to see how the cation structure of ILs affected the corrosion inhibition of carbon steel in 1 M HCl. The chem. structure of ILs was verified by elements anal., Fourier-transform-IR (FTIR), thermo gravimetric (TGA), NMR (¹HNMR, D₂O, ¹³C NMR) and hetero-nuclear single-quantum correlation (HSQC). The inhibitory efficiency was measured using mass loss and electrochem. tests and varied from 62.5% to 97.2%. The Langmuir model accurately defined their adsorption on a steel substrate. Adsorption of novel ILs on steel substrates is a mixed physisorption and chemisorption method. To ensure the mechanism of adsorption of current ionic liquids, FTIR and UV spectra were employed.

Turunen, Lotta published the artcileHalogen Bonds of Iodonium Ions: A World Dissimilar to Silver Coordination, Synthetic Route of 52358-73-3, the publication is Bulletin of the Chemical Society of Japan (2021), 94(1), 191-196, database is CAplus.

A distinct difference between the three-center halogen bond and the analogous three-center coordinative bond of silver is demonstrated by computational, X-ray crystallog. and solution NMR spectroscopic investigations of their complexes with a bidentate Lewis base. Iodine(I) preferentially forms an entropically favored monomeric complex, whereas silver(I) forms enthalpically favored dimeric complexes. Counterion coordination considerably influences the structure of the silver complexes in the solution and solid state, whereas it does not have notable effect on the analogous halogen bond.
