Pendant polymer-based organic electrodes consisting of redox-active quinones are promising for the next generation rechargeable batteries owing to their fast redox kinetics and structural diversity design. Many commercially available norbornene monomers have been popular choices preparing pendant polymer electrodes, since these enable numerous synthetic routes attaching groups. However, often s...

Atom efficient processes such as the Diels-Alder reaction (DA) and the ring-rearrangement metathesis (RRM) have been used to design new polycycles. In this regard, ruthenium alkylidene catalysts are effective in realizing the RRM of bis-norbornene derivatives prepared by DA reaction and Grignard addition. Here, fused polycycles are assembled which are difficult to produce by conventional synthe...

The detection of nerve agent simulants is achieved by the photoinduced electron transfer (PET) mechanism. A ‘‘turn-on’’ fluorescence response upon phosphorylation at 8-hydroxyquinoline of norbornene-based triazolyl functionalized 8-hydroxyquinoline (NCHQ) followed by intramolecular rearrangement provides very intense green emission. The detection limit of polymer (PNCHQ) coated paper strips is ...

A lactose-bearing norbornene imide template was polymerized using (Cy3P)2Cl2Ru=CHPh to produce a lactose-substituted neoglycopolymer. The resulting polymer showed a 100-fold overall increase in inhibitory potency (5-fold increase on a per saccharide residue basis) compared to monomeric lactose in both a galectin-binding assay and an Erythrina corallodendrum hemagglutination assay.

Results of a study of the valence electronic structure of norbornene (C(7)H(10)), up to binding energies of 30 eV, are reported. Experimental electron momentum spectroscopy (EMS) and theoretical Green's function and density functional theory approaches were utilized in this investigation. A stringent comparison between the electron momentum spectroscopy and theoretical orbital momentum distribu...

The detection of nerve agent simulants is achieved by the photoinduced electron transfer (PET) mechanism. A "turn-on" fluorescence response upon phosphorylation at 8-hydroxyquinoline of norbornene-based triazolyl functionalized 8-hydroxyquinoline () followed by intramolecular rearrangement provides very intense green emission. The detection limit of polymer () coated paper strips is 25 ppb with...
