Escamilla, Maria;Pachuta, Kevin;Huang, Kuan;Klingseisen, Michael;Cao, Huaixuan;Zhang, Huichun;Sehirlioglu, Alp;Pentzer, Emily research published 《 Polymer particles armored with cobalt oxide nanosheets for the catalytic degradation of bisphenol A》, the research content is summarized as follows. 2D particle surfactants are attractive for the formation of highly stable emulsions and use as templates to prepare composite structures with performance properties dependent on the composition Cobalt oxide nanosheets (CONs) are a relatively understudied class of 2D particle surfactants that can be produced by the chem. exfoliation of lithium cobalt oxide, a transition metal oxide known for excellent gas-sensing, catalytic, and electrochem. properties. Here, we report a simple method to access CONs stabilized oil-in-water Pickering emulsions and use these as templates to prepare particles with a core of polymer and shell of CONs. Salt-flocculated CONs produce emulsions with droplets of hydrophobic monomer (e.g., styrene) in water that are stable for at least 24 h, and suspension free radical polymerization is used to produce CON-armored particles. Characterization by XPS, SEM (SEM), and thermal gravimetric anal. (TGA) confirmed the presence of CONs on the surface of the polymer core. We then demonstrated the CON-armored polymer particles can activate the oxidant peroxymonosulfate (PMS) for the degradation of bisphenol A (BPA). Freshly prepared and artificially aged CON-armored particles showed full degradation of BPA in less than an hour and no decrease in activity was observed after two uses. CON-armored particles combine high surface area of the nanosheets with the ease of recoverability of the particles.

Herein, the first example of 1,2-dicarbonylation of alkenes by photocatalysis was represented. Key to success was that N(n-Bu)₄⁺ not only associates with the alkyl anion to avoid protonation, but also activated the α-keto acid to underwent electrophilic addition The α-keto acid was employed both for acyl generation and electrophilic addition By tuning the reductive and electrophilic ability of the acyl precursor, unsym. 1,4-dicarbonylation was achieved for the first time.

Clothier, Glenn K. K.;Guimaraes, Thiago R.;Moad, Graeme;Zetterlund, Per B. research published 《 Expanding the Scope of RAFT Multiblock Copolymer Synthesis Using the Nanoreactor Concept: The Critical Importance of Initiator Hydrophobicity》, the research content is summarized as follows. Precise multiblock copolymer synthesis coupled with self-assembly offers morphol. control on length scales ranging from a few nanometers to micrometer scale, providing enormous opportunities for future development of advanced materials and applications. The scope of multiblock copolymer synthesis via RAFT polymerization has recently been expanded by application of the nanoreactor concept for emulsion polymerization This enabled use of slow propagating monomers, such as styrenes and methacrylates, in multiblock synthesis. However, severe limitations attributed to the high polymer glass transition temperature (T_g) of some polymers have hitherto remained. The use of monomers that give such high T_g polymer effectively prevented penetration of aqueous phase-generated radicals into the polymer particles wherein the RAFT functionality is located. We here demonstrate that these constraints can be relieved by judicious choice of the radical initiator. Multiblock homopolymers were synthesized by seeded RAFT emulsion polymerization using initiators that differ substantially in hydrophobicity. Ten sequential chain extensions using tert-Bu methacrylate (T_g of PtBMA = 118°C) with targeted block DP = 100 were conducted at 80°C for each initiator. Markedly narrower mol. weight distributions were obtained when more hydrophobic initiators were used. The same polymerizations targeting low T_g polymer (PnBMA; T_g = 20°C) resulted in only minor differences in control when the different initiators were used, supporting our hypothesis on the role of radical penetration. The present results are anticipated to significantly expand the scope of RAFT polymerization in aqueous emulsion by allowing access to a wider range of low dispersity multiblock copolymers.

Dadashi-Silab, Sajjad;Kim, Khidong;Lorandi, Francesca;Schild, Dirk J.;Fantin, Marco;Matyjaszewski, Krzysztof research published 《 Effect of halogen and solvent on iron-catalyzed atom transfer radical polymerization》, the research content is summarized as follows. Efficient transfer of halogen atoms is essential for controlling the growth of polymers in atom transfer radical polymerization (ATRP). The nature of halogens may influence the efficiency of the halogen atom transfer during the activation and deactivation processes. The effect of halogens can be associated with the C-X bond dissociation energy and the affinity of the halogens/halides to the transition metal catalyst. In this paper, we study the effect of halogens (Br vs. Cl) and reaction media in iron-catalyzed ATRP in the presence of halide anions as ligands. In Br-based initiating systems, polymerization of methacrylate monomers was well-controlled, whereas Cl-based initiating systems provided limited control over the polymerization The high affinity of the Cl atom to the iron catalyst renders it less efficient for fast deactivation of growing chains, resulting in polymers with mol. weights higher than predetermined by Δ[M]/[RX]o and with high dispersities. Conversely, Br can be exchanged with higher efficiency and hence provided good control over polymerization Decreasing the polarity of the reaction medium improved the polymerization control. Polymerizations using ppm levels of the iron catalyst in acetonitrile (a more polar solvent) yielded polymers with larger dispersity values due to the slow rate of deactivation as opposed to the less polar solvent anisole, which afforded well-controlled polymers with dispersity <1.2.
