The first example of nickel-catalyzed monofluoroalkylation of arylsilanes has been developed with readily available fluoroalkyl halides. This novel transformation has demonstrated high reactivity, broad substrate scope, excellent functional group tolerance, and mild reaction conditions. The selective activation of a relatively inert C-Si bond for slow release of aryl carbanion is the key reason for reducing the amount of arylmetal species, which makes this method more promising for fluorine-containing modification of complex bioactive mols. Mechanistic investigations indicate that a free fluoroalkyl radical is involved in this catalytic cycle.

Wang, Min published the artcileRadical Monofluoroalkylative Alkynylation of Olefins by a Docking-Migration Strategy, HPLC of Formula: 401-55-8, the publication is Angewandte Chemie, International Edition (2019), 58(49), 17646-17650, database is CAplus and MEDLINE.

A radical-mediated monofluoroalkylative alkynylation of alkenes is disclosed for the first time. The reaction demonstrates a remarkably broad substrate scope in which both activated and unactivated alkenes are suitable starting materials. The concurrent addition of an alkynyl and a monofluoroalkyl group onto an alkene proceeds through a docking-migration sequence, affording a vast array of valuable fluoroalkyl-substituted alkynes. Many complex natural products and drug derivatives are readily functionalized, demonstrating that this method can be used for late-stage alkynylation.

Wang, Shuaifeng published the artcilePalladium-Catalyzed anti-Selective Fluoroalkylboration of Internal and Terminal Alkynes, Safety of Ethylbromofluoroacetate, the publication is Organic Letters (2018), 20(18), 5631-5635, database is CAplus and MEDLINE.

A Pd-catalyzed anti-stereospecific alkyne fluoroalkylboration, including mono-, di-, and perfluoroalkylboration, has been developed with fluoroalkyl halides and diboron reagents. The reaction is effective for both internal and terminal alkynes. It provides straightforward and streamlined access to functionalized 1,2-fluoroalkylboronated alkenes in a highly regio- and stereocontrolled manner. Preliminary studies suggest that this reaction is enabled by the combination of radical alkylation and metal-catalyzed borylation, thus leading to the realization of three-component trans-carboboration of alkynes for the first time.

In this manuscript, two PDI derivatives I [X = N] and I [X = O] with unsym. N-substitution of amine and ester-bridge were designed and synthesized. These two compounds were characterized by NMR, Fourier transform IR (FT-IR), and high-resolution mass spectrometry (HRMS). The photophys. properties were studied by UV-Vis absorption and fluorescence spectroscopy. Cyclic voltammograms of I [X = N] and I [X = O] were investigated and HOMO and LUMO energy levels of both two PDIs were estimated as -6.2 and -3.9 eV, resp. Thermal properties were also studied by thermogravimetric anal. (TGA) and differential scanning calorimetry (DSC). I [X = N] was assembled into nanotubes while I [X = O] was assembled into nanobelts resp., via a reprecipitation method. I [X = N] and I [X = O] show good potential application in organic devices such as solar cells, organic field-effect transistors (OFETs) and so on.

Gao, Heqi published the artcileA dentin hypersensitivity treatment using highly stable photothermal conversion nanoparticles, Name: 2-Bromo-3-(2-ethylhexyl)thiophene, the publication is Materials Chemistry Frontiers (2021), 5(8), 3388-3395, database is CAplus.

Most of the currently available com. photothermal agents suffer from issues in terms of photothermal instability and low photothermal conversion efficiency (PCE), which indeed impair their practical applications in disease treatment. Herein, a type of biocompatible organic nanoparticles (namely NDTB NPs) for an effective photothermal treatment with a high PCE of 40.6% was developed, which showed far higher photothermal stability compared with that of the clin. used indocyanine green. In addition, NDTB NPs combined with laser are significantly more effective than only laser irradiation in phototheranostic dental hypersensitivity treatments. This study thus provides an insight into the development of advanced photothermal NPs for practical phototheranostic applications.

Public anxiety and concern from cesium pollution in oceans have been back on the agenda since tons of nuclear waste water were announced to be poured into oceans. Cesium ion can easily enter organisms and bioaccumulate in animals and plants, thus its harm is chronic to humans through food chains. Here we showed a kind of hybrid ionic liquid membrane (HILM) for detection of cesium ion in seawater through CsPbBr₃ perovskite fluorescence. With sustainability in mind, HILM was built frugally. The lowest cost of HILM is below 3 cents per piece. The HILM can detect cesium ion quickly with eye-readable fluorescence signal. Ultracheap, portable, easy-to-use on-site detection device could offer benefit for personal security and applications in environment science and ecol. in the future decades.

Tang, Yixiao published the artcileBlack-to-transmissive polymer films via electrochemical copolymerization with high-performance electrochromic and supercapacitor bifunction, Recommanded Product: 1-Bromododecane, the publication is Solar Energy Materials & Solar Cells (2022), 111857, database is CAplus.

The black-to-transmissive electrochromic polymer has significant value with practical applications. Integration of electrochromic and supercapacitor bifunctional materials can indicate its capacitor level by visual color change in real-time. In this paper, based on three EDOT derivative monomers were associated to phenanthrocarbazole/benzotriazole/benzothiadiazole, M1, M2 and M3, a novel ternary random copolymer film was successfully prepared by electrochem. copolymerization Since the corresponding homopolymers of three monomers are red, green and blue in the neutral state resp., and their oxidation states are all transparent, therefore the obtained ternary random copolymer films show the black-to-transmissive electrochromic behavior. The copolymer film pCo-2 was prepared via electrochem. copolymerization with suitable monomers feed ratio (1: 1.5: 1 of M1: M2: M3). Benefit from ternary random electrochem. copolymerization, the pCo-2 copolymer displays excellent electrochromic-supercapacitor properties among the similar bifunctional materials, with fast response time, high optical contrast, good cycling stability and large area (volume) specific capacitance. The electrochromic supercapacitor device based on pCo-2//PEDOT can make an LCD run continuously. This work provides an available general approach to realizing black-to-transmissive electrochromism towards electrochromic-supercapacitor bifunctional applications.
