Gu, Yiting published the artcileDefunctionalization of sp³ C-Heteroatom and sp³ C-C Bonds Enabled by Photoexcited Triplet Ketone Catalysts, Recommanded Product: 1-Bromododecane, the publication is ACS Catalysis (2022), 12(2), 1031-1036, database is CAplus.

A general strategy for enabling a light-induced defunctionalization of sp³ C-heteroatom and sp³ C-C bonds with triplet ketone catalysts and bipyridine additives was disclosed. This protocol was characterized by its broad scope without recourse to transition metal catalysts or stoichiometric exogeneous reductants, thus offering a complementary technique for activating σ sp³ C-C(heteroatom) bonds. Preliminary mechanistic studies suggest that the presence of 2,2′-bipyridines improves the lifetime of ketyl radical intermediates.

Di Yang published the artcileStudy on mechanism of a simple method to regulate salt tolerance of hydrophobically associating water-soluble polymers, Synthetic Route of 143-15-7, the publication is Colloids and Surfaces, A: Physicochemical and Engineering Aspects (2022), 128266, database is CAplus.

Salt tolerance is one of the important properties of hydrophobically associating water-soluble polymers (HAWSPs). In this work, HAWSPs with different hydrophobic monomer (M12) contents (0.3 mol% and 0.5 mol%) were synthesized. The viscosity of two polymers was measured. Mol. simulation (MS) were carried out to elucidate the salt tolerance mechanism. Results show that the polymer with a higher M12 content exhibits better salt tolerance. With increasing salt content, the radius of gyration of the polymers continuously decreases when M12 content is low, while it tends to increase and then decrease under high M12 contents. Combined with the spatial conformation, it can be found that only sufficient hydrophobic monomers can enhance the association effect of the polymers, forming more hydrophobic microregions and improving the viscosity. The radial distribution function results demonstrate the little effect of salt on hydrogen bonds. This work illustrates that simply adjusting the content of hydrophobic monomers is an effective strategy to regulate the salt tolerance of the polymers, which can significantly reduce the cost of salt-tolerant polymers.

Ma, Hao published the artcileEmulsifying stability and viscosity reduction for heavy crude oil in surfactant-polymer composite system, HPLC of Formula: 143-15-7, the publication is Journal of Molecular Liquids (2022), 119713, database is CAplus.

Heavy crude oil is one of the most precious and complex mol. mixtures available, with considerable economic relevance. Nevertheless, its high viscosity and complicated chem. compositions pose an exceptional challenge for viscosity reduction with a compound emulsification system in heavy oil exploitation. Here, two types of polymers were synthesized and compounded with surfactant SDS to reduce the heavy crude oil viscosity. Their emulsifying properties in demineralized water and mineralized water were measured to evaluate their differences from macroscopic views. Furthermore, the corresponding emulsion system (involving resins, asphaltenes, surfactants, polymers, etc.) was also simulated and computed using mol. dynamics simulation to investigate the relationships of various compositions on emulsifying properties at the mol. scale. The results showed that the surfactant-polymer composite system formed by the amphiphilic polymer had an obvious advantage in emulsifying stability with the water segregation rate of 60.6% after 48 h in the simulated salinity and the viscosity reduction rate reached more than 92.1% after optimization. Besides, the electrostatic interaction is the major part of the potential energy in emulsion systems at a ratio of 87.8%. The divalent cations (Ca²⁺ and Mg²⁺) resulted in the shrinkage or collapse of mol. conformation of the water-soluble polymer by 19%. The variation of interaction energy in salt solutions for different emulsifying systems caused a series of exptl. and simulated distinctions, such as solution viscosity, interface behaviors, the number of hydrogen bonds, and the spatial distribution function, which ultimately determined the emulsifying properties of heavy crude oil. Notably, this work offers insight into the interactions and influences of complex mixtures in oil-water systems. It also facilitates to design and apply the innovative functional chem. additives in heavy crude oil extraction and transportation.

Westphal, Eduard published the artcileReaching Room-Temperature Mesomorphism through Expansion of the Tristriazolotriazine Core with Alkoxybenzoate Units, Application of 1-Bromododecane, the publication is European Journal of Organic Chemistry (2022), 2022(29), e202200378, database is CAplus.

The tristriazolotriazine (TTT) N-heterocycle, despite being a relatively new mesogenic core for use in discotic liquid crystals, has already demonstrated its importance and promising characteristics. In this work, we extended the knowledge about the TTT, increasing the core size with alkoxybenzoate units, as well as evaluating how the expansion and number of peripheral chains affected the thermal and photophys. properties, both in solution and spin-coated films. Their thermal behavior and self-assembly were studied by differential scanning calorimetry, polarizing optical microscopy and X-ray diffraction with synchrotron radiation, while the photophysics was investigated by UV-Vis absorption and fluorescence spectroscopy. The results show that, despite a considerable decrease in the fluorescence quantum yield with the core expansion, the mesomorphic properties are significantly enhanced, with two products showing Colh mesophase at room temperature, with large range of mesomorphism and very good thermal stability. It was also demonstrated how structural changes affected the self-assembly properties.

Lo, Ping Hsun published the artcileThe effect of C_X (alkyl groups) on the migration insertion polymerization (MIP) of ^PFpC_X [^PFp = (PPh₂(CH₂)₃Cp)Fe(CO)₂], Recommanded Product: 1-Bromododecane, the publication is Polymer (2022), 124574, database is CAplus.

Migration insertion polymerization (MIP) of organometallic monomers, ^PFpC_X [^PFp = (PPh₂(CH₂)₃Cp)Fe(CO)₂, C_X = (CH₂)_X-1CH₃, X = 12 or 18] was performed under various conditions. The oligomerization occurred in accompany with the monomer cyclization generating ^PFpC_X small rings at the early stage, which was followed by a complete cyclization of the oligomers generating P(^PFpC_X)_n macrocycles. ^PFpC_X small rings could be completely removed via precipitating the crude products in a poor solvent for the macrocycles. The solution and bulk MIP of ^PFpC_X (X = 12 or 18) had a similar cyclization rate but both were significantly accelerated at a higher MIP temperature (100°C). It is explained by the temperature-dependent tendency for the cyclization. The dependence of d.p. (DP) on the MIP conditions was discussed and the self-assembly of resultant P(^PFpC₁₂)_n was examined

Zhao, Mengyu published the artcileConverting thermally activated delayed fluorescence into hybridized local and charge-transfer via an addition acceptor moiety, COA of Formula: C12H25Br, the publication is Organic Electronics (2022), 106365, database is CAplus.

High-efficiency blue materials for Organic Light Emitting Diodes (OLEDs) are challenging but urgently needed, especially for solution-processed devices. Herein, based on a model compound of acridine-benzophenone, two blue materials were designed and synthesized, with the addnl. electron-withdrawing groups benzophenone and pentafluorobenzophenone connected to the acridine donor resp. to prepare BC and BC5F. The solution-processed OLED based on BC showed an emission peak at 486 nm, while the device with BC5F showed the electroluminescent peak at 478 nm. BC featured the thermally active delayed fluorescent (TADF) properties, but BC5F exhibited hybridized local and charge-transferring (HLCT) characteristics. This work showed that linking addnl. acceptors to the donor side could not only achieve deeper blue emission but also change the luminescent mechanism. Therefore, we provided a new strategy to manipulate the transition between TADF and HLCT.

Fan, Guanglin published the artcileRubber-like composites with tunable thermal- and photo-responsive shape memory properties, Safety of 1-Bromododecane, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2022), 137534, database is CAplus.

Shape memory polymers (SMPs) are crosslinked networks with mol. switches to control network mobility and thus macroscopic deformation. The network crosslinking and the mol. switches make most SMPs behave like hard plastics, with very few exceptions whose extensibilities are comparable to rubbers and elastomers. Here we report a class of composites that comprise polystyrene-b-ethylene-co-butylene-b-styrene (SEBS) as elastic matrixes and azobenzene derivatives (ADs) as mol. switches. The incorporation of the ADs does not impair the extensibility of the SEBS substrates, and the tensile strains of the prepared composites can exceed 900% even when the content of the ADs reaches 30 wt%. The thermal- and photo-responsive solid-liquid transitions of the ADs are responsible for the shape memory effects of the composites. The photo-responsive shape recovery process can be completed within 2 s, and 2D-to-3D shape transformations are realized on the samples fixed with tensile strains by spatiotemporal control of UV irradiation On another aspect, the chem. structures of the ADs can be tailored to regulate their m.ps. and thus the thermal responsive shape memory properties of the composites. Furthermore, different pieces of composites can be combined by hot-pressing to exhibit spatially tailorable thermal responsive shape recovery behaviors. The facile preparation and interesting shape memory properties of the rubber-like composites can inspire the design of soft SMPs with more promising applications.

Han, Lin published the artcileMulti-hydroxyl containing organo-vermiculites for enhanced adsorption of coexisting methyl blue and Pb(II) and their adsorption mechanisms, Related Products of bromides-buliding-blocks, the publication is Colloids and Surfaces, A: Physicochemical and Engineering Aspects (2022), 129542, database is CAplus.

To address the competitive adsorption of complex wastewater components on organo-vermiculites (organo-Vts), multi-hydroxy containing gemini surfactants varying in alkyl chain length (G₁₂, G₁₄ and G₁₆) are designed and applied for modifying Na-vermiculite (Na-Vt) targeted to the removal of co-existing MB and Pb(II). Organo-Vts exhibit enhanced hydrophobicity and enlarged interlayer spacing compared with Na-Vt, with the saturated modifier dosage reaching as low as 0.4 CEC of Na-Vt. Shorter alkyl chain induces suitable packing d. and interlayer environment, endowing G₁₂-Vt the highest adsorption capacity towards MB/Pb(II) compared with G₁₄-Vt and G₁₆-Vt (178.3/63.0 mg/g compared with 143.7/38.1 and 88.6/36.6 mg/g, resp.). Freundlich isotherm and PSO kinetic model are agreeable (the values of R² are higher than 0.98) with the endothermic adsorption processes. Notably, a simultaneous effect in binary-component system is obtained, and the maximum adsorption capacities of G₁₂-Vt towards MB/Pb(II) reaching 349.9 and 124.5 mg/g, which are 1.96 and 1.95 times higher than single-component system, resp. Combination of theor. fitting and mol. simulation co-reveals the adsorption mechanism: the simultaneous effect is due to the providing of addnl. active sites by the adsorbed MB, which is stronger than that between Pb(II) and the modifier. Existence of π-ion interaction enhances the retention of Pb(II) for a further step. This work broadens a new research perspective for complex wastewater treatment and provides a deep understanding of the stimulative adsorption mechanism between dyes and metal ions.
