Dodecyl tannin derivative linked with 1,2,3-triazole was prepared by the click reaction of dodecyl azide and alkynylated tannin. The structure of tannin derivative was identified by FT-IR spectrometer and elemental analyzer, and the surface activity, antioxidant activity and antimicrobial activity of tannin derivative were studied. The surface tension of tannin derivative was significantly reduced because of the introduction of long chain alkyl groups, and the lowest surface tension was 38.87 mN/m at 1.0 mg/mL. The tannin derivative had strong ability to scavenge 1,1-diphenyl-2-picrylhydrazyl radical, the scavenging rate could reach 89.08% at 0.25 mg/mL. The tannin derivative exhibited strong antibacterial activity against E. coli and S. aureus due to the increased fat-solubility of tannin derivative and the introduction of antibacterial triazole groups in mol. structure of tannin derivative, and the bacteriostatic ratios of tannin derivative against E. coli and S. aureus were 92.16% and 89.21% at 2.0 mg/mL, resp. The tannin derivative can be used as good candidates for antibacterial packaging or antioxidant supplements.

Zhang, Yuchi published the artcileCyclodextrin single isomer-based vesicle for chlorin e6 delivery and enhanced efficiency of photodynamic therapy for cancer treatment, Safety of 1-Bromododecane, the publication is Journal of Molecular Liquids (2022), 118683, database is CAplus.

In the field of cancer therapy, photodynamic therapy (PDT) is an emerging treatment modality that utilized light, photosensitizers (PSs), and oxygen to generate reactive oxygen species (ROS) to destroy tumor sites selectively. Conventional PSs experience issues such as poor water solubility and low bioavailability. The widely developed PS delivery nanosystems can address these problems, but most of them usually depend on relatively complex components and time-consuming synthesis procedures. Therefore, PS delivery vehicles with more easily obtained components and simpler preparation methods need to be explored. In this study, amphiphilic and cationic single-isomer cyclodextrin (CD-IL) was designed, which could co-assemble with chlorin e6 (Ce6, a com. available PS) via multiple non-covalent interactions. The obtained nanovesicles (CD-CE) could not only overcome the inherent drawbacks of free Ce6, but also exhibit improved PDT efficacy in a series of cell-related experiments, including favorable stability, preferable cellular uptake, and enhanced phototoxicity. Thus, CD-CE prepared by the co-assembly of simple building blocks could be a facile option for PDT clin. applications.

2-Mercapto-5-methyl-1,3,4-thiadiazole (MMT) based ionic liquids were synthesized, their corrosion inhibition behavior and tribol. performance were systematically evaluated. Electrochem. experiments showed MMT based ILs exhibited surprising corrosion inhibition efficiencies. The ILs adsorption behavior obeys Langmuir isotherm. Friction tests demonstrated MMT based ILs performed excellent lubrication properties, compared to [BMIM][BF4]. Combining with anal. of SEM and XPS, it can be concluded that the prominent lubrication performance ascribed to the coexistence of adsorption layer and tribo-film. Therefore, versatile ILs designed in this paper have gathered two significant abilities for industrial applications, which are high corrosion inhibiting performance and excellent lubricating properties. This work is instructive for structure design of multifunctional ILs and will promote industrial application of MMT based ILs in the future.

Mu, Bin published the artcilePositional Isomerism-Mediated Copolymerization Realizing the Continuous Luminescence Color-Tuning of Liquid-Crystalline Polymers, Synthetic Route of 143-15-7, the publication is Macromolecules (Washington, DC, United States) (2022), 55(13), 5332-5341, database is CAplus.

Liquid crystals with color-tunable light emission are important for a variety of applications; however, achieving multicolor light-emitting liquid crystals whose emission colors can be fine-tuned remains challenging because the limited derivatization of mesogenic fluorophores disfavors the diversity of the emission. Here, we present a positional isomerism-mediated copolymerization strategy to obtain liquid-crystalline polymers with continuous luminescence color-tuning ability. The introduced α-/β-cyanostilbene positional isomers possess very similar mol. structures, thus reducing the risk of assembly heterogeneity and facilitating the formation of a homogeneous and consistent liquid crystal mesophase. Meanwhile, a significant electronic effect was caused for fluorophores with positional isomerization, allowing the efficient tuning of emission colors via copolymerization Especially with a gradual change in the composition of the copolymers, the emission color shift behaved in a continuous manner from blue to green. These cyanostilbene-based liquid-crystalline polymers also showed reversible photochromic fluorescence switching ability. This approach highlights the value of positional isomers to prepare color-tunable solid-state light-emitting materials, allowing control and fine-tuning of the emission property while maintaining the ordered assembly ability.

Zhang, Nan published the artcileAlkylated lignin with graft copolymerization for enhancing toughness of PLA, Application of 1-Bromododecane, the publication is Journal of Materials Science (2022), 57(19), 8687-8700, database is CAplus.

A green modification method for effectively enhancing toughness of PLA was established. Herein, alk. lignin (LG) was firstly alkylated with dodecane, and then grafted with lactide (LA). The alkylated lignin-lactide graft copolymer (GLG-g-LA) was obtained via ring-opening polymerization (ROP). GLG-g-LA copolymer can be utilized as a functional filler to toughen polylactic acid (PLA) packaging film. The 31P-NMR of alkylated lignin (GLG) demonstrated that the peak of phenolic hydroxyl groups disappeared completely, while the relative peak intensity of carboxyl hydroxyl groups decreased significantly. The grafting rate of GLG-g-LA copolymer was improved more than twice times compared with lignin-lactide graft copolymer (LG-g-LA). Then LG-g-LA and GLG-g-LA copolymer were mixed with PLA to prepare different PLA composite films via casting method, resp. Particularly, the elongation at break of PLA/GLG-g-LA2 composite film increased to 41.98%, which was more than 20 times higher than PLA. In general, PLA/GLG-g-LA composite film with toughness, excellent UV barrier, water resistance and controllable gas permeation could be used as high-performance and biodegradable materials in packaging field.

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.

One-step synthesis and micropatterning of different types of carbon nanomaterials, such as amorphous carbon or three-dimensional graphene which have versatile electrochem., thermal, and mech. properties, are advantageous for the fabrication of microelectronics, sensors, and wearable devices. Here, we report a direct laser writing method to simultaneously synthesize and pattern graphitic carbon from liquid organic precursors. We have tested a wide range of liquid organic precursors and identified the chem. characteristics that are beneficial for successful laser-induced solvothermal deposition. The laser-deposited carbon exhibits a paracryst.-to-polycrystalline structure and has elec. resistivities on the order of 10^-3 to 10^-4 Ω m which is tunable through variations in the laser power. Such properties of the laser-deposited carbon, coupled with the ability to direct-write custom patterns with microscale resolution, make these carbon materials exciting candidates for use in applications such as energy storage and sensing.

In response to frequent oil spills and increasing discharges of oily wastewater, a variety of materials and methods have been developed to treat with oil-water mixtures In this paper, a simple and versatile method to modify a broad spectrum of natural polymer surfaces (wood aerogel, pulpboard, filter paper, cotton cloth, electrospinning gelatin film, ultrafine polypropylene fiber) was reported. This modification was based on aryl diazo compounds with hydrophobic functional groups as precursors, which were thermally activated to generate highly active carbene intermediates and induce the X-H (X = O, C,…) insertion reaction on the surface of substrates. The success of surface modification was demonstrated by the irreversible changes of the surface properties and the application on multi-behavior oil/water separation Moreover, according to the Owens-Wendt-Rabel-Kaelble method, the influence of the dispersion force and the polar force on various material surfaces was given to explore the separation mechanism. This one-step modification provides a facile and efficient strategy to achieve renewable, biodegradable, and environmentally friendly materials and surfaces with low surface energy, which offers considerable potential applications on disposal of oil pollution in the environment.
