Investigation on Three New Metal Carboxydiphosphonates: Syntheses, Structures, Magnetic and Luminescent Properties
A new multifunctionalized phosphoric acid, (2-(diphosphonomethylamino)nicotinic acid, Py(COOH)(NHCH(PO3H2)2), H5L1), has been employed as ligand for the construction of new metal phosphonates. By reacting it with different metal chlorides under hydrothermal condition, three new transition metal phosphonates, namely, [Co2(HL1)(H2O)5][H2O]3 (1), Zn(H3L1) (2) and [Cd(H3L1)(H2O)2][H2O] (3) were succ...

High Capacity Hydrogen and Nitric Oxide Adsorption and Storage in a Metal-Organic Framework
Gas adsorption experiments have been carried out on a copper benzene tricarboxylate metal?organic framework material, HKUST-1. Hydrogen adsorption at 1 and 10 bar (both 77 K) gives an adsorption capacity of 11.16 mmol H2 per g of HKUST-1 (22.7 mg g-1, 2.27 wt %) at 1 bar and 18 mmol per g (36.28 mg g-1, 3.6 wt %) at 10 bar. Adsorption of D2 at 1 bar (77 K) is between 1.09 (at 1 bar) and 1.20(at &l...

Hysteretic Adsorption and Desorption of Hydrogen by Nanoporous Metal-Organic Frameworks
Adsorption and desorption of hydrogen from nanoporous materials, such as activated carbon, is usually fully reversible. We have prepared nanoporous metal-organic framework materials with flexible linkers in which the pore openings, as characterized in the static structures, appear to be too small to allow H2 to pass. We observe hysteresis in their adsorption and desorption kinetics above the super...

26. Photoinduced Metal-Free Atom Transfer Radical Polymerization of Biomass-Based Monomers
Well-defined polymers derived from biomass feedstock (e.g., soybean oil, rosin acid, and furfural) were successfully prepared by metal-free atom transfer radical polymerization (ATRP). In the presence of photoredox catalysts and UV irradiation, three biomass-based methacrylate monomers were efficiently polymerized with good control over molecular weight and dispersi...

(CP) Dithiocarbamate-modified starch derivatives with high heavy metal adsorption performance
In this work, three types of dithiocarbamate (DTC)-modified starch derivatives including DTC starch (DTCS), DTC enzymolysis starch (DTCES) and DTC mesoporous starch (DTCMS) were developed, which showed the significant heavy metal adsorption performance. The adsorption ability of these three DTC modified starch derivatives followed the sequences: DTCMS > DTCES > DTCS. I...

[Polym. Chem.] Polymer Brushes on Metal–Organic Frameworks by UV-Induced Photopolymerization
Metal–organic frameworks (MOFs) are extremely promising candidates for application in diverse fields. However, a limitation to the widespread use of MOFs is the absence of a facile and efficient chemical modification method which can greatly improve their poor processability and stability without altering the inherent outstanding chemical and physical properties. Herein, we report a universal pos...

Heavy Metal Ions Removal by Nano-Sized Spherical Polymer Brushes
Nano-sized spherical polymer brushes (SPBs) consisting of both a polystyrene (PS) core and a brush shell of poly (acrylic acid ) (PAA), poly(N-acrylcysteamine) (PSH), or poly(N-acrylcysteamine-co-acrylic acid) (P(SH-co-AA)), were prepared by photo-emulsion polymerization. The core-shell structure was observed by dynamic light scattering and transmission electron microscopy. Due to the strengthen...

Directly Probing molecular ordering at the buried polymer/metal interface
We developed a methodology to directly probe molecular ordering at the buried polymer/metal interface. Using sum frequency generation (SFG) vibrational pectroscopy, we observed ordering of ester methyl groups at the buried poly(methyl acrylate) (PMA)/silver (Ag) interface. In order to directly probe the PMA/Ag interface, we collected SFG signal from a thin PMA film sandwiched between a...

Molecular Ordering of Phenyl Groups at the Buried Polystyrene/Metal Interface
Understanding molecular structures of buried polymer/metal interfaces is important for the design and development of polymer adhesives used in advanced microelectronic devices and polymer anti-corrosion coatings for metals. The buried interfacial molecular structure between polystyrene (PS) and silver (Ag) was investigated using infrared-visible sum frequency generation (SFG) vibrational sp...

196. Nitrogen-Doped Graphene Nanoribbons as Efficient Metal-Free Electrocatalysts for Oxygen Reduction.
Nitrogen-doped graphene nanoribbon (NGNR) nanomaterials with different nitrogen contents have been facilely prepared via high temperature pyrolysis of graphene nanoribbons (GNR)/polyaniline (PANI) composites. Here, the GNRs with excellent surface integration were prepared by longitudinally unzipping the multiwalled carbon nanotubes. With a high length-to-width ratio, the GNR sheets are prone to fo...
