A Ru-containing single chain nanoparticle (SCNP) was prepared in three steps using radical polymerization of pentafluorophenylacrylate, post-polymerization functionalization with three different alkylamines, and coordination of Ru. The polymer was characterized by 1H NMR, 19F NMR, UV-vis, and DLS. The catalytic activity of the Ru-SCNP for Ru-catalyzed cleavage of allylcarbamates was evaluated by fluorescence spectroscopy and a higher percent conversion and initial rate of reaction was observed when compared to that of the free catalyst in buffer and cell media. The catalytic SCNP was also shown to perform tandem catalysis with β-galactosidase.

Das, Anindita; Lin, Shaojian; Theato, Patrick published the artcile< Supramolecularly Cross-Linked Nanogel by Merocyanine Pendent Copolymer>, Electric Literature of 71195-85-2, the main research area is supramolecularly crosslinked nanogel merocyanine pendent polyacrylic.

Directional dipole-dipole interaction mediated antiparallel dimerization of merocyanine dye (MD) has been explored for maneuvering supramol. assembly of MD-conjugated flexible macromols. leading to a cross-linked nanogel. The MD-functionalized copolymer was synthesized by a newly developed organocatalytic transesterification strategy for postpolymn. functionalization of poly(pentafluorophenyl acrylate) (polyPFPA)-based reactive copolymer. Presence of ∼35% pendant MD attached to a coil-like polymer chain leads to spontaneous formation of highly emitting crosslinked nanogel with efficient container property and appreciable stability in toluene owing to strong dimerization propensity among the MD. Considering the significance of MD in the context of nonlinear optics and photovoltaics, these results not only enrich the toolbox for engineering macromol. assembly, but also open up new possibilities for future organic materials.

Brooks, Karson; Razavi, Mir Jalil; White, Evan M.; Wang, Xianqiao; Locklin, Jason published the artcile< The formation and evolution of creased morphologies using reactive diffusion in ultrathin polymer brush platforms>, HPLC of Formula: 71195-85-2, the main research area is creasing ultrathin polymer brush modification reactive diffusion morphol.

Precisely controlling the morphol. in thin film coatings has emerged as an important tool used to tune surface properties in a wide variety of applications. Previously, a method is reported to fabricate nanoscale surface creases with a high degree of control over crease size and shape using microcontact printing to perform post-polymerization modification on reactive polymer brush surfaces. In this work, this approach has been expanded to manipulate crease morphol. in reactive thin films, using only a drop of a reactive, viscous polymer, and crease formation has been investigated with a combination of exptl. observations and computational validations. The effects of various rate constants of the reactive polymer brush scaffold, hydrostatic pressure within the droplet of reactive polymer, diffusion profile, and the evolution of the creased morphologies with reaction time are examined in order to better understand crease formation in ultrathin films.

Xue, Wenwen; Mutlu, Hatice; Theato, Patrick published the artcile< Post-polymerization modification of polymeric active esters towards TEMPO containing polymers: a systematic study>, Recommanded Product: Perfluorophenyl acrylate, the main research area is acrylic polymer radical functionalization secondary battery cathode.

Organic radical batteries (ORB) are a novel promising class for energy storage, particularly featuring a fast charging capability and extraordinary cycle life. The representative polymer, i.e. poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl methacrylate) (PTMA), is usually synthesized by a post-polymerization oxidation method. As an alternate strategy for developing TEMPO-containing polymers, we focused on the post-polymerization modification of poly(pentafluorophenyl acrylate) and poly(pentafluorophenyl methacrylate) with three different TEMPO nucleophiles by transesterification or amidation reactions. Optimizing the conditions of the post-polymerization functionalization reaction by varying different parameters, such as the type of nucleophile, catalyst and solvent, the feeding ratios of catalysts and nucleophiles, along with reaction time and temperatures, resulted in structurally distinct TEMPO containing polymers with varying backbone composition Intriguingly, poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl acrylamide) revealed the highest degree functionalization with TEMPO (96.2%) within 3 h. under considerably mild conditions, while poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl methylmethacrylamide) exhibited the lowest TEMPO content owing to the steric hindrance from Me group on both the methacrylate chain and the TEMPO derivative All other four TEMPO containing polymers had a radical content similar to PTMA (66.6%) synthesized by the post-oxidation methodol. Noteworthy, compared to TEA (trimethylamine), DMAP (4-dimethylaminopyridine) facilitated an efficient ester bond cleavage independent of the polymer precursor, thus, side reactions such as hydrolysis were increased. Though hydrolysis side reaction occurred, the resulting carboxylic acid group was proven to accelerate ion transfer in a certain way during the redox process. Furthermore, due to the higher TEMPO content, poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl acrylamide) exhibited a 12-22 mAh/g higher specific capacity compared to the PTMA-oxidation when running at 5C for 500 cycles.

Suga, Takeo; Aoki, Kohei; Yashiro, Toshiaki; Nishide, Hiroyuki published the artcile< ""Click"" Incorporation of Radical/Ionic Sites into a Reactive Block Copolymer: A Facile and On-Demand Domain Functionalization Approach toward Organic Resistive Memory>, Product Details of C9H3F5O2, the main research area is Click amidation radical ionic reactive block copolymer resistive memory; charge-transport; ionic polymer; nitroxide radical; organic electronics; postpolymerization modification.

Reversible addition-fragmentation chain transfer polymerization yields reactive block copolymers bearing the pentafluorophenyl ester (PFPA) group, and subsequent Click amidation using 2,2,6,6-tetramethylpiperidine-N-oxyl- and imidazolium-functionalized primary amines produces the corresponding functional block copolymers, leading to installation of statistical radical- and ionic sites into the PFPA segment. The monolayered thin film devices fabricated using the obtained block copolymers exhibit repeatable switching of elec. conductivity (on/off ratio > 103) under a bias voltage, which reveals that the coexistence of radicals and ions in the same spherical domain of the copolymer layer is a prerequisite for repeatable switching memory.

Kibrom, Asmorom; Roskamp, Robert F.; Jonas, Ulrich; Menges, Bernhard; Knoll, Wolfgang; Paulsen, Harald; Naumann, Renate L. C. published the artcile< Hydrogel-supported protein-tethered bilayer lipid membranes: a new approach toward polymer-supported lipid membranes>, Safety of Perfluorophenyl acrylate, the main research area is Paracoccus microscopyhydrogel supported protein tethered bilayer lipid membrane.

Polymer-supported bilayer lipid membranes offer great opportunities for the investigation of functional membrane proteins. Here we present a new approach in this direction by introducing a thin hydrogel layer as a soft cushion’ on indium-tin oxide (ITO), providing a smooth, functional surface to form the protein-tethered BLM (ptBLM). ITO was used as a transparent electrode, enabling simultaneous implementation of electrochem. and optical waveguide techniques. The hydrogel poly(N-(2-hydroxyethyl)acrylamide-co-5-acrylamido-1-carboxypentyl-iminodiacetate-co-4-benzoylphenyl methacrylate) (P(HEAAm-co-NTAAAm-co-MABP)) was functionalized with the nickel chelating nitrilotriacetic acid (NTA) groups, to which cytochrome c oxidase (CcO) from Paracoccus denitrificans was bound in a well defined orientation via a his-tag attached to its subunit I. Given that the mesh size of P(HEAAm-co-NTAAAm-co-MABP) was smaller than the protein size, binding to the hydrogel occurred only on the top of the layer. The lipid bilayer was formed around the protein by in situ dialysis. Electrochem. impedance spectroscopy showed good elec. sealing properties with a resistance of ∼1 MΩ cm2. Furthermore, surface plasmon resonance optical waveguide spectroscopy (SPR/OWS) indicated an increased anisotropy of the system after formation of the lipid bilayer. Cyclic voltammetry in the presence of reduced cytochrome c demonstrated that CcO was incorporated into the gel-supported ptBLM in a functionally active form.

Triggering antibody-mediated innate immune mechanisms to kill cancer cells is an attractive therapeutic avenue. In this context, recruitment of endogenous antibodies to the cancer cell surface could be a viable alternative to the use of monoclonal antibodies. We report on antibody-recruiting polymers containing multiple antibody-binding hapten motifs and cyclooctynes that can covalently conjugate to azides introduced onto the glycocalyx of cancer cells by metabolic labeling with azido sugars.

Thermoresponsive gold nanoparticles were prepared by conjugation of short pentapeptide sequences, containing the elastin-like peptide (ELP) repeat unit Val-Pro-Gly-Val-Gly (VPGVG), to a well-defined active ester prepolymer, poly(pentafluorophenyl acrylate) (pPFPA), itself prepared by RAFT polymerization Polymers with number-average chain lengths of 25, 50, 75 and 100 were prepared The cloud points of their aqueous solutions was found to decrease with chain length and peptide sequence, and varied from 76 to 42 °C. CD indicated that the cloud point behavior was accompanied by a reversible change in peptide conformation from a random coil to a β-turn. The resulting thermoresponsive elastin peptide side-chain polymers (ESPs) were then conjugated to gold nanoparticles (GNPs) by ligand exchange. The resulting ESP-GNPs similarly displayed thermo-reversible aggregation with transition temperature (Tt) values of 65 and 35 °C for ESPs of chain length 75 and 100, resp.
