An amphiphilic anionic azobenzene derivative, soluble in water, formed a monolayer on an aqueous subphase containing a water-soluble polycation. The monolayers were transferred onto solid substrate by the Langmuir-Blodgett (LB) technique. XPS measurements showed that ion exchange reaction proceeded almost completely at the air-water interface and that the ratio of the monomer unit of the polycation to the azobenzene was almost unity. UV/visible absorption and IR measurements indicated that the azobenzene photoisomerized reversibly in the LB films on alternate illumination with UV and visible light. Furthermore, a reversible morphol. change induced by light was observed in the LB films with AFM. Before illumination, the surface of the single-layer LB film was very smooth with a surface undulation of less than 1 nm. On illumination with UV light, however, a number of hills, with the height of ca. 5 nm and the diameter of the base of ca. 100 nm, appeared on the film surface. These structures almost disappeared on illumination with visible light. This indicates that the widely accepted assumption that photoisomerization should not change the two-dimensional structures significantly does not hold in the present case.

Han, Hoon published the artcileDevelopment of a proton exchange membrane based on trifluoromethanesulfonylimide-grafted polybenzimidazole, Name: Sodium 3-bromopropane-1-sulfonate, the publication is Polymer Journal (Tokyo, Japan) (2021), 53(12), 1403-1411, database is CAplus.

Trifluoromethanesulfonylimide-grafted polybenzimidazole (PBI-TFSI) was synthesized for proton exchange membrane (PEM) applications. Its proton conductivity was (a) less dependent on humidity and (b) higher than that of conventional fluorine-based PEM (Nafion) and propanesulfonic acid-grafted PBI (PBI-PS) at a relative humidity of 40%. The chem. structure of PBI-TFSI was investigated using ¹H and ¹⁹F NMR and Fourier transform IR spectroscopy. The membranes exhibited good transparency, flexibility, and thermal stability up to 350 °C. Membranes with different side chain grafting ratios were prepared, and the water uptake and hydration number of the PBI-TFSI membranes were lower than those of the PBI-PS membranes, most likely because of the hydrophobicity of the side chain. The higher proton concentration provided by TFSI with stronger acidity than PS might be the reason for the higher proton conductivities of PBI-TFSI.

A series of seven new metal complexes (metal = Ni^II, Cu^II, Pt^II and VO²⁺) with substituted salphen ligands have been prepared and their duplex and G-quadruplex DNA affinities determined The selectivity of the complexes towards a given DNA topol. is dictated by several factors including geometry, overall charge and substitution pattern of the complex. Also the two platinum(II)-salphen complexes developed as part of this series are emissive. Confocal microscopy studies were carried out with these two complexes using four different cell lines (CHO, HeLa, U2OS and HepG2). The cell permeability and localization are different for the two probes and highly dependent on the cell line used.

Wang, Yipu published the artcileVisualizing Aβ deposits in live young AD model mice with a simple red/near-infrared-fluorescent AIEgen, Category: bromides-buliding-blocks, the publication is Science China: Chemistry (2022), 65(2), 339-352, database is CAplus.

Precise and early detection of β-amyloid (Aβ) deposits in situ and in real time is pivotal to the diagnosis and early intervention of Alzheimer’s disease (AD). Optical imaging stands out to be a promising technique for such a task; however, it still remains a big challenge, due to the lack of high-performance imaging contrast agent. Restricted by poor blood-brain barrier (BBB) penetrability, short-wavelength excitation and emission, as well as the aggregation-caused quenching effect, the widely used gold-standard probes cannot be used for early in-vivo imaging of Aβ deposits. Herein, we integrate the Aβ deposits-favored geometry, amphiphilic and zwitterionic mol. structure, extended D-π-A electronic structure, and 3D conformation into one mol., facilely establishing a simple and economic imaging contrast agent that enjoys high specificity and affinity to Aβ deposits, good BBB penetrability, bright red/near-IR fluorescence, low interference from autofluorescence, aggregation-induced emission (AIE) feature, high signal-to-noise ratio (SNR), and high contrast. In-vitro, ex-vivo, and in-vivo experiments with different strains of mice indicate that AIE-CNPy-AD holds the universality to Aβ deposits identification. Noteworthily, AIE-CNPy-AD is even able to precisely trace the small and sparsely-distributed Aβ deposits in AD model mice as young as 4-mo-old APP/PS1 mice, the youngest having Aβ deposits. Moreover, the present probe could clearly reveal the increase and enlargement of Aβ deposits as the mice grow. Therefore, AIE-CNPy-AD might be an ideal alternative for early AD diagnosis and highly reliable monitoring of AD progression.

A wide range of biorelevant applications, particularly in pharmaceutical formulations and the food and cosmetic industries, require the stabilization of two water-soluble blended components which would otherwise form incompatible biphasic mixtures Such water-in-water emulsions can be achieved using Pickering stabilization, where two-dimensional (2D) nanomaterials are particularly effective due to their high surface area. However, control over the shape and size of the 2D nanomaterials is challenging, where it has not yet been possible to examine chem. identical nanostructures with the same thickness but different surface areas to probe the size-effect on emulsion stabilization ability. Hence, the rationale design and realization of the full potential of Pickering water-in-water emulsion stabilization have not yet been achieved. Herein, we report for the first time 2D poly(lactide) platelets with tunable sizes (with varying coronal chem.) and of uniform shape using a crystallization-driven self-assembly methodol. We have used this series of nanostructures to explore the effect of 2D platelet size and chem. on the stabilization of a water-in-water emulsion of a poly(ethylene glycol) (PEG)/dextran mixture We have demonstrated that cationic, zwitterionic, and neutral large platelets (ca. 3.7 × 10⁶ nm²) all attain smaller droplet sizes and more stable emulsions than their resp. smaller platelets (ca. 1.2 × 10⁵ nm²). This series of 2D platelets of controlled dimensions provides an excellent exemplar system for the investigation of the effect of just the surface area on the potential effectiveness in a particular application.

Polysulfones (PSUs) carrying short pendant alkyl side-chains with terminal sulfonic acid units were prepared and studied as proton-conducting membrane materials. The 1st step in the preparation involved quenching of lithiated PSU with SO₂ gas, resulting in sulfonated PSU. In the 2nd step, the lithium sulfonate units on the polymer were reacted with sodium 2-bromoethanesulfonate, sodium 3-bromopropanesulfonate, or 1,4-butane sultone to produce sulfoethylated, sulfopropylated, or sulfobutylated PSUs, resp. Anal. by TG showed that membranes based on the sulfoalkylated polymers were stable up to ∼300° under N₂ atmosphere. Calorimetry measurements revealed that the modified polymers absorbed large amounts of non-freezing water, corresponding to 11-14 mol H₂O/mol SO₃H under immersed conditions. The proton conductivity of a membrane based on a PSU carrying 0.9 sulfopropyl chains per repeating unit is 77 mS/cm at 70° under humidifying conditions.

Pairs of polystyrene-based random copolymers with balanced number of pendant basic or acidic groups were synthesized utilizing the template strategy. The same poly[(4-hydroxystyrene)-ran-styrene] was used as a template backbone for modification. Two different synthetic approaches for the functionalization were applied. The first one involved direct functionalization of the template backbone through alkylation of the phenolic groups with suitable reagents. The second modification approach was based on “click” chem., where the introduction of alkyne groups onto the template backbone was followed by copper-catalyzed 1,3 cycloaddition of aliphatic sulfonate- or amine-containing azides. Both synthetic approaches proved to be highly efficient as evidenced by ¹H-NMR analyses. The thermal properties were evaluated by differential scanning calorimetry and thermal gravimetric analyses and were influenced by the type of functionality and the modification method. The ether-linked functional copolymers were thermally more stable than their “clicked” analogs. © 2010 Wiley Periodicals, Inc. © 2010 Wiley Periodicals, Inc.

The ability to control nanostructure shape and dimensions presents opportunities to design materials in which their macroscopic properties are dependent upon the nature of the nanoparticle. Although particle morphol. has been recognized as a crucial parameter, the exploitation of the potential shape-dependent properties has, to date, been limited. Herein, we demonstrate that nanoparticle shape is a critical consideration in the determination of nanocomposite hydrogel properties. Using translationally relevant calcium-alginate hydrogels, we show that the use of poly(L-lactide)-based nanoparticles with platelet morphol. as an adhesive results in a significant enhancement of adhesion over nanoparticle glues comprised of spherical or cylindrical micelles. Furthermore, gel nanocomposites containing platelets showed an enhanced resistance to breaking under strain compared to their spherical and cylindrical counterparts. This study opens the doors to a change in direction in the field of gel nanocomposites, where nanoparticle shape plays an important role in tuning mech. properties.

Miclotte, Matthieu P. J. published the artcileTuning the Cloud-Point and Flocculation Temperature of Poly(2-(diethylamino)ethyl methacrylate)-Based Nanoparticles via a Postpolymerization Betainization Approach, Synthetic Route of 55788-44-8, the publication is ACS Polymers Au (2021), 1(1), 47-58, database is CAplus and MEDLINE.

The ability to tune the behavior of temperature-responsive polymers and self-assembled nanostructures has attracted significant interest in recent years, particularly in regard to their use in biotechnol. applications. Herein, well-defined poly(2-(diethylamino)ethyl methacrylate) (PDEAEMA)-based core-shell particles were prepared by RAFT-mediated emulsion polymerization, which displayed a lower-critical solution temperature (LCST) phase transition in aqueous media. The tertiary amine groups of PDEAEMA units were then utilized as functional handles to modify the core-forming block chem. via a postpolymn. betainization approach for tuning both the cloud-point temperature (T_CP) and flocculation temperature (T_CFT) of these particles. In particular, four different sulfonate salts were explored aiming to investigate the effect of the carbon chain length and the presence of hydroxyl functionalities alongside the carbon spacer on the particle’s thermoresponsiveness. In all cases, it was possible to regulate both T_CP and T_CFT of these nanoparticles upon varying the degree of betainization. Although T_CP was found to be dependent on the type of betainization reagent utilized, it only significantly increased for particles betainized using sodium 3-chloro-2-hydroxy-1-propanesulfonate, while varying the aliphatic chain length of the sulfobetaine only provided limited temperature variation. In comparison, the onset of flocculation for betainized particles varied over a much broader temperature range when varying the degree of betainization with no real correlation identified between T_CFT and the sulfobetaine structure. Moreover, exptl. results were shown to partially correlate to computational oligomer hydrophobicity calculations Overall, the innovative postpolymn. betainization approach utilizing various sulfonate salts reported herein provides a straightforward methodol. for modifying the thermoresponsive behavior of soft polymeric particles with potential applications in drug delivery, sensing, and oil/lubricant viscosity modification.
