Abstract: Various embodiments disclosed relate to a method of preparing aryl fluorinated ether compounds. The method involves contacting an aryl halide with a fluorinated alcohol in the presence of a photocatalyst, a base, and irradiation with electromagnetic radiation comprising a wavelength between about 200 nm and about 800 nm. The present invention also provides a method of late-stage photochemical modification of a biologically active compound, such as drugs or agrochemicals. Fluorinated derivatives of griseofulvin, clofibrate, and 2,4-D methyl ester are described herein.

Abstract: Methods for making molecular sieves are provided. The molecular sieves are comprised of thin semiconductors films in which a plurality of apertures is defined. The apertures are non-circular, nanoscale openings with tapered sidewalls that selectively pass certain molecules, while discriminating against the passage of other molecules.
