Abstract:

Ligands for transition metals are disclosed herein, which may be used in various transition-metal-catalyzed carbon-heteroatom and carbon-carbon bond-forming reactions. The disclosed methods provide improvements in many features of the transition-metal-catalyzed reactions, including the range of suitable substrates, number of catalyst turnovers, reaction conditions, and efficiency. For example, improvements have been realized in transition-metal-catalyzed cross-coupling reactions.

US Classification:

4302701, 430322

Abstract:

The invention disclosed herein provides highly efficient methods and materials useful for surface patterning via polymerization reactions. In particular, by using a light-mediated radical polymerization procedure, brush formation from a surface can be regulated spatially by controlling the area of irradiation. In embodiments of the invention, polymer chain length (and/or film thickness) can be effectively controlled by either the amount of time a surface is irradiated with light (temporal control) or by the intensity of light allowed to reach the surface. Such light-mediated control allows artisans to use the disclosed processes to form complex 3-dimensional structures on a variety of surfaces. Moreover, the simplicity of the disclosed polymerization processes allows them to be adapted for use in a wide range of technologies.
