Support Curvature and Conformational Freedom Control Chemical Reactivity of Immobilized Species

Abstract

We show that bimolecular reactions between species confined to the surfaces of nanoparticles can be manipulated by the nature of the linker, as well as by the curvature of the underlying particles.

Introverted Phosphorus‐Au Cavitands for Catalytic Use

“…In this instance we expected toluene would compete for the catalytic site better and perhaps mesitylene would result in improved yields, but the opposite was true. We moved to 9-ethynylanthracene (Table 2, Entries 5 and 6), [30] whereas the bulk of the substrate has increased drastically, so too has the reactivity of the alkyne.…”

Emerging Enzyme-Based Technologies for Wastewater Treatment

“…While there was no single nanosupport recommended as the optimum one for all enzymes being tested, some general trends have been observed. For instance, research has shown that more curved nanosupports are more desirable than their flatter counterparts because they tend to limit the nonspecific interactions as well as enzyme-enzyme interactions (73,(86)(87)(88).
