Chemical reactions, effect organized assemblies

General Discussion—Effect of Organized Assemblies on Chemical Reactions... 

As evidenced by this symposium, the use of micelles and other organized assemblies to control the selectivity of chemical reactions has recently attracted much attention. In most of these cases, micelles or vesicles have been used as a means of separating charged intermediates formed by electron transfer reactions, thereby preventing the back reaction. The effects of the micelle or vesicle are usually dramatic. 

The surface reactivities of ultrathin organic and macromolecular films and assemblies are of central importance to the targeted immobihzation reactions of biomolecules. Compared to reactions that occur rapidly in solution, steric effects and locally altered environments may adversely affect reactivity in substrate-supported architectures [36,37]. Hence the relationship of layer structure to reactivity, highly localized in situ analysis of surface chemical reaction kinetics, and the maximization of surface coverage (molecular loading) by extending the dimensionality of the reactive platform from 2D to quasi-3D will be elaborated on in the following sections.
