Secondary interactions are demonstrated to direct the stability of well-defined Ru-NHC-based heterogeneous alkene metathesis catalysts. By providing key stabilization active sites, higher catalytic performance is achieved. Specifically, they can be described as between metal center (active site) and surface functionality support, have been detected by surface-enhanced (1)H-(29)Si NMR spectroscopy ligand (31)P solid-state catalyst precursor. They present only when attached via a flexible...
The differentiation of stem cells can be modulated by physical factors such as the micro- and nano-topography extracellular matrix. One important goal in cell research is to understand concept that directs into a specific lineage nanoscale environment. Here, we demonstrate paths exist controlling only polymer surfaces. Altering depth (on nanometric scale) micro-patterned surface structures allowed increased adhesion human mesenchymal (hMSCs) with osteoblasts, absence osteogenic medium. Small...
Thanks to successful cohabitation between graphene and ionic liquids (ILs), a large avenue can be opened for the design of functional nanomaterials in broad range applications, including catalysis, gas separation electrochemistry.
Using a two-step procedure based on (i) anchoring an organogold precursor within the channels of functionalized ordered mesoporous silica containing mercapto groups; (ii) followed by chemical reduction, we prepared materials gold (0) nanoparticles exclusively located pore channels. By modifying precursor/mercapto groups ratio, demonstrate necessity complexation prior to reduction. this methodology, content as high 16.1 wt % with narrow size distribution regularly distributed pores material...
Several strategies to synthesize fluorinated (co)polymers containing phosphorus groups and their applications are reviewed. First, original fluoromonomers bearing atoms supplied from relevant routes. They may possess linked the ethylenic carbon with different structures, such as F2C═CF- or H2C═C(CF3)- a phosphonated ω-function adjacent an aliphatic aromatic linker, while other monomers display difluoromethylene dialkylphosphonate end group -CF2–P(O)(OR)2. Then, copolymers were obtained...
Abstract Closo‐decahydrodecaborate anion, [B 10 H ] 2− , is one of the most notable clusters in family hydroborates, partly attributed to its unique electronic structure and thermal chemical stability. The major challenge development chemistry resides functionalization via activation exo‐polyhedral B−H bonds B−L generate attractive molecular construction modules or ‘archetypes’ useful applications. To date, closo‐[B cage has been functionalized with a wide range functional groups ‐L such as...
Mesoporous hybrid materials containing cyclam moieties inside the framework have been obtained by using a neutral templating route; these with large pores and narrow pore size distribution are shown to be particularly suitable for grafting functional organic groups channel giving rise bifunctional materials.
Highly ordered hydrothermally stable SBA-15 mesoporous silica containing phosphonic acid groups are synthesised for the first time by using amphiphilic block copolymers as structure-directing agents.
The silicon atom is pentacoordinate in cations of salts like 1, which can be prepared, for instance, a redox reaction the corresponding silane (with I2, X = I) or transformation with electrophiles PhCoCl (X Cl) Ph3C+BF (X= BF4). These compounds were completely characterized; conductivity titrations confirm that they are ionic.
Functionalized SBA-15 type materials containing mercaptopropyl groups have been used for controlling the growth of gold(0) nanoparticles from HAuCl4 or AuCl(THT) which were chemically complexed within channels prior to mild chemical reduction.
To fight against nosocomial infection initiated by colonization of medical devices, a strategy enabling the direct and fast functionalization silicone surfaces is proposed. This proceeds in site‐specific way using original hybrid silylated antibacterial peptides. safe up‐scalable method guarantees covalent robust immobilization with correct orientation bioactive moiety. Importantly it also avoids multi‐step chemical modifications surface or multi‐layer polymer coatings. As proof concept,...
Conceiving biomaterials able to mimic the specific environments of extracellular matrices are a prerequisite for tissue engineering applications. Numerous types polymers (PEG, PLA, etc.) have been used design biocompatible scaffolds, but they still less efficient than natural biopolymers such as collagen extracts. Chemically modified and loaded with different bioactive factors, afford an environment favourable cell proliferation differentiation. Unfortunately, present several drawbacks, weak...
As an intermediate state between liquid and solid materials, hydrogels display unique properties, opening a wide scope of applications, especially in the biomedical field. Organic are composed organic network cross-linked via chemical or physical reticulation nodes. In contrast, hybrid defined by coexistence inorganic moieties water. Inorganic polymerization, i.e. sol-gel process, is one main techniques leading to hydrogels. The chemoselectivity this method proceeds through hydrolysis...
Inorganic polymerization as a cross-linking method for 3D printing of PEG–peptide hydrogels.
Abstract For the first time, POSS‐based coordination polymers (CPs) have been structurally characterized. These CPs were obtained in high yield via self‐assembly reactions of thioether‐functionalized polysilsesquioxanes with Cu I salts under mild conditions. Single crystal analyses revealed formation 3D networks incorporating different secondary building units (SBUs) as connection nodes. The nature ‐SAr functionality allows a fine‐tuning cluster nuclearity, that is, butterfly‐shaped 2 X or...
This paper describes a general way permitting the quantitative introduction of strongly chelated transition metal ions. For that purpose, direct synthesis mesoporous silica containing chloropropyl groups has been achieved by using three different nonionic surfactants (n-hexadecylamine, tergitol 15-S-12, and triblock copolymer P123) as structure-directing agents. Substitution located within pores cyclam was then investigated; (1,4,8,11-tetraazacyclotetradecane) is well-known for its...
A new mesostructured hybrid organic–inorganic silica host with internal anchored acetylacetonate groups has been used as a matrix for the growing and organization of Fe3O4 nanoparticles. The approach consists in impregnation subsequent organic solution-phase decomposition molecular precursor Fe[(OC(CH3))2CH]3 into pores. magnetic nanocomposite material obtained was fully characterized using transmission electron microscopy (TEM), infrared spectroscopy (IR), nitrogen physisorption, X-ray...
