Whitaker, R. D. published the artcileIodine monochloride and iodine trichloride systems involving pyridine and quinoline, Application of Pyridine Iodochloride complex, the publication is Journal of Inorganic and Nuclear Chemistry (1962), 285-9, database is CAplus.

Spectrophotometric studies indicate that only addition compounds with 1:1 stoichiometries are present in significant concentrations in CCl⁴ solutions of ICl or ICl, with heterocyclic amines. However, thermal studies reveal that in the solid state, in addition to the expected 1:1 type compounds, the system ICl₄-pyridine forms C₅H₆N.2ICl₃ (m.p. 140°) and ICl₃.2C₅H₅N (m.p. 69° incongruent) and the system ICl₂-quinoline forms ICl₂.2C₉H₇N (m.p. 81°). The system ICl-quinoline forms only the 1:1 type compound, and a reinvestigation of part of the system ICl-pyridine confirmed the absence of a compound with a mole ratio of 1: 2 of ICl to pyridine.

Zhai, Tianran published the artcileFerrocene metallopolymers of intrinsic microporosity (MPIMs), COA of Formula: C6H13I, the publication is Chemical Communications (Cambridge, United Kingdom) (2022), 58(2), 238-241, database is CAplus and MEDLINE.

We show here that non-network metallopolymers can possess intrinsic microporosity stemming from contortion introduced by metallocene building blocks. Metallopolymers constructed from ferrocenyl building blocks linked by phenyldiacetylene bridges are synthesized and possess BET surface areas up to 400 m² g^-1. As solubility imparted by pendant groups reduces porosity, copolymerization is used to simultaneously improve both accessible surface area and solubility Spectroscopic anal. provides evidence that mixed valency between neighboring ferrocenyl units is supported in these polymers.

Schuiten, Eva D. published the artcilePromiscuous dehalogenase activity of the epoxide hydrolase CorEH from Corynebacterium sp. C12, Related Products of iodides-buliding-blocks, the publication is ACS Catalysis (2021), 11(10), 6113-6120, database is CAplus.

Haloalkane dehalogenases and epoxide hydrolases are phylogenetically related and structurally homologous enzymes that use nucleophilic aspartate residues for an S_N2 attack on their substrates. Despite their mechanistic similarities, no enzymes are known that exhibit both epoxide hydrolase and dehalogenase activity. We screened a subset of epoxide hydrolases, closely related to dehalogenases, for dehalogenase activity and found that the epoxide hydrolase CorEH from Corynebacterium sp. C12 exhibits promiscuous dehalogenase activity. Compared to the hydrolysis of epoxides like cyclohexene oxide (1.41μmol min^-1 mg^-1), the dehalogenation of haloalkanes like 1-bromobutane (0.25 nmol min^-1 mg^-1) is about 5000-fold lower. In addition to the activity with 1-bromobutane, dehalogenase activity was detected with other substrates like 1-bromohexane, 1,2-dibromoethane, 1-iodobutane, and 1-iodohexane. This study shows that dual epoxide hydrolase and dehalogenase activity can be present in one naturally occurring protein scaffold.

Liu, Zhiru published the artcileStructure-property relationship of poly(2,6-dimethyl-1,4-phenylene oxide) anion exchange membranes with pendant sterically crowded quaternary ammoniums, Recommanded Product: 1-Iodohexane, the publication is Journal of Membrane Science (2021), 119693, database is CAplus.

Steric hindrance engineering is of great significance to the preparation of new stable organic cations and durable polymeric anion exchange membrane materials. In this work, we presented a study of the structure-property relationship in quaternized poly (2,6-dimethyl-1,4-phenylene oxide) containing bulky Pr, iso-Pr, or cyclohexyl-functionalized quaternary ammonium moieties. To our surprise, PPO-iP membranes possessing isopropyl-based QA cations showed higher water uptake than n-propyl- and cyclohexyl-containing analogs (PPO-nP and PPO-CH), in which obvious microphase-separated morphol. was found. Thus, PPO-iP membranes displayed the highest hydroxide conductivity at 20°C in water (37.3 mS/cm, IEC = 1.90 mmol/g). A standard protocol (1 M or 2 M NaOH at 60°C) was used to determine the chem. stability of model cations and membranes both having sterically crowded QAs. Minor loss (<2%) in conductivity was observed for PPO-CH membranes after the treatment in 2 M NaOH at 60°C for 216 h, highlighting the excellent alk. stability, while significant degradation of PPO-iP and PPO-nP was confirmed by NMR characterization of the aged samples. In addition, the prepared PPO-based AEMs having sterically crowded QA cations were compared in alk. H₂/O₂ fuel cells, demonstrating that the highly conductive PPO-iP membrane exhibited a peak power d. of 182 mW/cm² under optimized testing conditions.

Lima, Eurico published the artcilePicolylamine-functionalized benz[e]indole squaraine dyes: Synthetic approach, characterization and in vitro efficacy as potential anticancer phototherapeutic agents, Application of 1-Iodohexane, the publication is European Journal of Medicinal Chemistry (2022), 114071, database is CAplus and MEDLINE.

Squaraine dyes are a family of compounds known for their relevant photophys. and photochem. properties potentially useful as photosensitizing agents. Since pyridines have been introduced into the skeleton of several families of compounds to enhance their pharmacol. activity, and this approach had not yet been performed on squaraines, novel dyes derived from benz[e]indole functionalized with picolyl- and dipicolylamine and N-Et and -hexyl chains were designed and synthesized. After being fully characterized, their interaction with human albumin was in vitro and in silico evaluated. Dyes were further assessed for their phototoxicity activity, and the most interesting ones were studied regarding cell localization and induction of morphol. cell changes, genotoxicity, apoptosis and cell cycle arrest. The mols. with N-Et chains showed the greatest in vitro light-dependent cytotoxic effects, particularly the zwitterionic squaraine dye and the one bearing a single pyridine unit, which also exhibited a more significant interaction with human albumin. Phenotypically, the cells incubated with these squaraines became smaller and rounded after irradiation, the effects varying with the tested concentration Genotoxic effects were observed even without irradiation, being more evident for the N-Et picolylamine-derived dye. The fluorescence emitted by Rhodamine 123 largely coincided with that emitted by the dyes, suggesting that they are found preferentially in mitochondria. After irradiation, an increase in the subG1 population was verified by propidium iodide-staining anal. by flow cytometry, indicative of cell death by apoptosis.

Lunzer, Markus published the artcileBeyond the Threshold: A Study of Chalcogenophene-Based Two-Photon Initiators, Formula: C6H13I, the publication is Chemistry of Materials (2022), 34(7), 3042-3052, database is CAplus and MEDLINE.

A series of nine soluble, sym. chalcogenophenes bearing hexyl-substituted triphenylamines, indolocarbazoles, or phenylcarbazoles was designed and synthesized as potential two-photon absorption (2PA) initiators. A detailed photophys. anal. of these mols. revealed good 2PA properties of the series and, in particular, a strong influence of selenium on the 2PA cross sections, rendering these materials especially promising new 2PA photoinitiators. Structuring and threshold tests proved the efficiency and broad spectral versatility of two selenium-containing lead compounds as well as their applicability in an acrylate resin formulation. A comparison with com. photoinitiators Irg369 and BAPO as well as sensitizer ITX showed that the newly designed selenium-based materials TPA-S and TPA-BBS outperform these traditional initiators by far both in terms of reactivity and dose. Moreover, by increasing the ultralow concentration of TPA-BBS, a further reduction of the polymerization threshold can be achieved, revealing the great potential of this series for application in two-photon polymerization (2PP) systems where only low laser power is available.

A series of fluoroaryl 1,3,4-oxadiazole derivatives I [R = Et, hexyl, decyl] substituted with different para terminal ethers were synthesized using S_NAr chem. to afford fluorescent and thermally reversible low mol. weight organogelators (LMWOs). S_NAr was used to synthesize these highly fluorinated organogelators in high purity and good yields starting from pentafluorobenzoic acid and 4′-hydroxy-4-biphenylcarbonitrile. These fluorinated 1,3,4-oxadiazole derivatives were characterized by elemental anal., FTIR and ¹H, ¹³C and ¹⁹F NMR spectroscopy. The photophys. properties of those organogelators were described. Both UV-visible absorption and fluorescence spectral profiles displayed a solvatochromic and solvatofluorochromic properties. The absorption maxima for the developed organogelators were monitored in the range of 260-289 nm, whereas the emission maxima were monitored in the range of 278-305 nm. The best gelation properties were monitored for the compound I [R = hexyl] in different solvents with critical gel concentrations in the range of 1.86-5.07 mM. The self-assembly process was monitored to occur via van der Waals forces and π-π stacks to result in gelation of solvents. Scanning electron microscope (SEM) demonstrated nanofiber-like structures (350-550 nm). The thermal stability of the compound I [R = hexyl] was monitored at 48°C. Both cytotoxicity and antimicrobial activity of the produced fluoroaryl 1,3,4-oxadiazole derivatives were explored to verify their potential use for biomedical applications, such as drug delivery and bioimaging.

Abusaif, Moustafa S. published the artcileEffect of different acceptors on N-hexyl carbazole moiety for dye-sensitized solar cells: design, characterization, molecular structure, and DSSC fabrications, Computed Properties of 638-45-9, the publication is Journal of the Iranian Chemical Society (2021), 18(4), 949-960, database is CAplus.

Hexyl carbazole derivatives are one of the most prominent dye scaffolds in the dye-sensitized solar cells (DSSCs). New substituted carbazole dyes such as DRA-HC, DCA-HC, and DTC-HC were synthesized for DSSCs. These dyes are containing hexyl moiety as electron donor and rhodanine-3-acetic acid, cyanoacetic acid and tetracyanoethylene as an electron acceptor linked to carbazole moiety. The relation between dye structures, photophys./electrochem., mol. structure and DSSC manufacturing had been discussed. All structures showed more pos. ground-state oxidation potential than I-/I-3 and more neg. excited state oxidation potential than the conduction band edge of the semiconductor. The highest efficiency of the DSSCs was obtained in the case of DCA-HC dye (η = 1.41%, VOC = 708 mV, FF = 0.81, and JSC = 2.45 mA cm^-2 with 100 mW cm^-2) compared to other synthesized dyes.
