The photophysical (fluorescence quantum yields and flu...

Sulphamethoxazole (SMX) is extensively used in humans and livestock, but its appearance in natural water raises environmental concerns. This study demonstrated that SMX and its degradation product, 3-amino-5-methylisoxazole (3A5MI), could be effectively degraded in microbial fuel cell (MFC) reac...

The direct labeling of biomolecules with fluorine-18 is highly desirable. An option is the ring-opening of an activated aziridine moiety in a biomolecule using 18F-fluoride. Therefore, a series of aziridine-based model compounds and three aziridine-based biomolecules four aziridine-based model c...

We have demonstrated the covalent functionalization of graphene by nitrene chemistry, resulting in highly dispersed aryl azides functionalized graphene. Two different ortho-substituted aryl azides having different aromatic ring (π-conjugation) and ester/anhydride substituent have been synthesiz...

Three N-vinylimidazole modified hyper-cross-linked resins (HP2, HP5, and HP8) were prepared and they were employed to adsorb Rhodamine B from aqueous solution. As the initial cross-linking degree increased, the Brunauer–Emmett–Teller surface area of the resins was approximately identical, whil...

In this work, three new polymeric coordination complexes were synthesized using squaric acid and 1-vinylimidazole. The structures of the coordination polymers, formed with Co(II), Zn(II), and Cd(II) ions, were characterized by elemental analysis, infrared spectroscopy (IR), thermal analysis (The...

A series of N-vinylimidazole-modified hyper-cross-linked resins was prepared, and the porosity and polarity of these resins were effectively tuned by altering the feeding amount of N-vinylimidazole in the polymerization. The results indicated that the Brunauer-Emmett-Teller surface area sharply ...

In search for magnetic nanoparticles with multifunctional complementary characteristics in this study, novel magnetite nanoparticles functionalized with vinylimidazole-rare earth complexes were analyzed. The morphology, size and structure of the obtained samples were determined by X-ray diffract...

Evodiae Fructus is used as a traditional Chinese medicine for the treatment of several kinds of diseases with its bioactive constituents. In this study, a capillary electrochromatography-mass spectrometry (CEC-MS) method was developed to determine three bioactive compounds including evodiamine, ...

A novel polymer monolith based on the dicationic crosslinker 3,3′-(hexane-1,6-diyl)bis(1-vinylimidazolium) bromide, the monomer 1-vinylimidazole and a ternary porogen mixture (1-propanol, decan-1-ol and water) was developed and optimized for capillary electrochromatography. This aim was accompl...

Room temperature ionic liquids (RTILs) are known to exhibit high CO2 solubility, which makes them interesting candidates for separation and purification of mixed gas streams. Particularly, RTILs based on imidazoles have shown very promising results. However, membranes of the corresponding poly(R...

A metal-free inorganic base-mediated highly stereoselective hydroamination of arylalkynes with imidazoles has been developed, and the corresponding N-vinylimidazoles were obtained in good yields and with moderate to excellent stereoselectivities (up to 99:1). For the electron rich alkynes, the r...

A new cationic pullulan derivative was obtained via graft copolymerization of N-vinylimidazole (NVI). Grafting of poly(N-vinylimidazole) (PNVI) onto pullulan has been achieved in aqueous medium using ammonium persulphate (APS) as the initiator. The effect of monomer concentration, pullulan conce...

Chitosan and poly(1-vinylimidazole) are both potential adsorbents to remove Cr(VI). Here, we designed the preparation of new adsorbents by combining chitosan and poly(1-vinylimidazole) to get the synergistic effect for the removal of hexavalent chromium. Trimethoxysilyl group terminated poly(1-v...
