Single-molecule imaging and kinetic analysis of intermolecular polyoxometalate reactions.

ABSTRACT: We induce and study reactions of polyoxometalate (POM) molecules, [PW₁₂O₄₀]^3- (Keggin) and [P₂W₁₈O₆₂]^6- (Wells-Dawson), at the single-molecule level. Several identical carbon nanotubes aligned side by side within a bundle provided a platform for spatiotemporally resolved imaging of ca. 100 molecules encapsulated within the nanotubes by transmission electron microscopy (TEM). Due to the entrapment of POM molecules their proximity to one another is effectively controlled, limiting molecular motion in two dimensions but leaving the third dimension available for intermolecular reactions between pairs of neighbouring molecules. By coupling the information gained from high resolution structural and kinetics exper
