Since the discovery of nickel-catalyzed cyclization of acetylene to benzene and cyclooctatetraene, transition-metal-activated cycloaddition of alkynes has become a powerful technique to construct ring compounds in organic synthesis. Although cyclo-trimerization and -tetramerization were discovered almost 70 years ago, direct metal-mediated acetylene oligomerization to polycyclic compounds has not been reported. Instead, cycloaddition of different alkynes, or alkynes with alkenes or arynes, has been used to synthesize polycyclic and other complex ring structures. In a recent Journal of American Chemical Society Communication, the Yang group reported the metal-activated bicycle-oligomerization of acetylene to naphthalene in a supersonic molecular beam experiment. In their work, laser-vaporized lanthanum atoms are used to activate acetylene molecules, naphthalene is detected in the form

On February 22, 2016 John Anthony, a Chemistry professor at the University of Kentucky had an article featured in the Nature Communications publication.  The article titled, "Reducing dynamic disorder in small-molecule organic semiconductors by suppressing large-amplitude thermal motions," deals with understanding performance vibrations in organic semiconductors.

All solids are composed of atoms or molecules, and at temperatures above absolute 0 (-460 °F) these molecules are vibrating rapidly.  Such vibrations decrease the performance of semiconductors (critical components in computer chips and modern video displays), because the movement of the molecules can deflect charges moving through the solid.      

Anthony's work with researchers in England and Belgium, investigates the specific nature of these vibrations and their impact on charge being

Full Professor John Anthony and Assistant Professor Chad Risko have joined forces in a recent publication in the ACS journal Chemistry of Materials titled "Dynamics, Miscibility, and Morphology in Polymer:Molecule Blends: The Impact of Chemical Functionality". Based on a series of acceptors constructed from trialkylsilylethynyl-substituted pentacenes designed and synthesized in the Anthony laboratory, the study presents a computational chemistry investigation of polymer:molecule blends with the polymer donor poly(3-hexylthiophene) (P3HT). Essential connections are made between the chemical structure of the acene acceptor and the nanoscale properties of the polymer:molecule blend, which include polymer and molecular diffusivity, donor–acceptor packing and interfacial (contact) area, and miscibility. The results point to the very significant role that seemingly modest changes in
