Polymer Mechanochemistry: Using Force to Direct Chemical Reactivity
Mechanochemistry, whereby chemical transformations are facilitated using mechanical force,
often induces reactivity that is otherwise inaccessible. In this presentation, we will describe how exogenous forces have been used to surmount thermally-inaccessible isomerization barriers,
facilitate retro-cycloadditions, and activate latent coupling or polymerization catalysts. In general, these trans...

Confined polymer brush gradients based on chemical nanolithography
Gradients mean that chemical or physical properties of components attached on substrates or substrates themselves gradually vary along one or more given directions. Gradients play an important role in vivo.

TEMPO in Chemical Transformations: From Homogeneous to Heterogeneous
The organic nitroxyl radical, TEMPO (2,2,6,6-tetramethylpiperidine-N-oxyl), finds a variety of industrial applications for chemical transformations. Due to the economic and environmental concerns, the recovery and reuse of TEMPO with maintained high activity are utmost important. In this critical review, we summarize the most important advances made by the scientific community in TEMPO immobiliz...

Interfacial Chemical Oxidative Synthesis of Multifunctional Polyfluoranthene
A novel polyfluoranthene (PFA) exhibiting strong visual fluorescence emission, a highly amplified quenching effect, and widely controllable electrical conductivity is synthesized by the direct cationic oxidative polymerization of fluoranthene in a dynamic interface between n-hexane and nitromethane containing fluoranthene and FeCl3, respectively. A full characterization of the molecular structure ...
