    • Amphiphilic hydroxyalkyl cellulose derivatives for amorphous solid dispersion prepared by olefin cross-metathesis 

      Dong, Yifan; Mosquera-Giraldo, Laura I.; Troutman, Jacob; Skogstad, Brittny; Taylor, Lynne S.; Edgar, Kevin J. (Royal Society of Chemistry, 2016-07-07)
      Olefin cross-metathesis (CM) has enabled design and synthesis of diverse, amphiphilic cellulose ether derivatives (e.g. of ethyl and methyl cellulose). In this paper, hydroxyalkyl cellulose was selected as a hydrophilic ...
    • Cooperative electrochemical water oxidation by Zr nodes and Ni–porphyrin linkers of a PCN-224 MOF thin film 

      Usov, Pavel M.; Ahrenholtz, Spencer R.; Maza, William A.; Stratakes, Bethany; Epley, Charity C.; Kessinger, Matthew C.; Zhu, Jie; Morris, Amanda (Royal Society of Chemistry, 2016-10-06)
      Here, we demonstrate a new strategy for cooperative catalysis and proton abstraction via the incorporation of independent species competent in the desired reactivity into a metal–organic framework (MOF) thin film. The ...
    • Imparting functional variety to cellulose ethers via olefin cross-metathesis 

      Dong, Yifan; Edgar, Kevin J. (The Royal Society of Chemistry, 2015-04-09)
      Olefin cross-metathesis is a valuable new approach for imparting functional variety to cellulose ethers. Starting from commercially available ethyl cellulose, terminally unsaturated alkyl groups were appended as metathesis ...
    • Influence of nucleobase stoichiometry on the self-assembly of ABC triblock copolymers 

      Zhang, Keren; Talley, Samantha J.; Yu, Ya Peng; Moore, Robert B.; Murayama, Mitsuhiro; Long, Timothy E. (Royal Society of Chemistry, 2016-05-11)
      ABC triblock copolymers bearing adenine- and thymine-functionalized external blocks self-assembled into long-range, ordered lamellar microphase-separated morphologies on non-patterned substrates. Intermolecular hydrogen ...
    • Multifunctional cellulose esters by olefin cross-metathesis and thiol-Michael addition 

      Meng, Xiangtao; Roy Choudhury, Shreya; Edgar, Kevin J. (Royal Society of Chemistry, 2016-04-25)
      Olefin cross-metathesis (CM) has been shown to be a versatile, mild, modular, and efficient approach to polysaccharide modification. One issue with regard to this approach is the susceptibility of the initial α,β-unsaturated ...
    • Non-isocyanate poly(amide-hydroxyurethane)s from sustainable resources 

      Zhang, Keren; Nelson, Ashley M.; Talley, Samantha J.; Chen, Mingtao; Margaretta, Evan; Hudson, Amanda G.; Moore, Robert B.; Long, Timothy E. (Royal Society of Chemistry, 2016-05-19)
      A two-step synthesis of epoxidation and carbonation afforded a hetero-functional AB monomer with cyclic carbonate and methyl ester (CC-ME) using plant oil-based methyl 9-decenoate and CO2. A unprecedented one-pot synthetic ...
    • Nucleobase-Functionalized ABC Triblock Copolymers: Self-assembly of Supramolecular Architectures 

      Zhang, Keren; Fahs, Gregory B.; Aiba, Motohiro; Moore, Robert B.; Long, Timothy E. (The Royal Society of Chemistry, 2014-06-24)
      RAFT polymerization afforded acrylic ABC triblock copolymers with self-complementary nucleobase-functionalized external blocks and a low-Tg soft central block. ABC triblock copolymers self-assembled into well-defined ...
    • Olefin cross-metathesis, a mild, modular approach to functionalized cellulose esters 

      Meng, Xiangtao; Matson, John B.; Edgar, Kevin J. (The Royal Society of Chemistry, 2014-09-02)
      Olefin cross-metathesis has been demonstrated to be a modular pathway for synthesis of a series of functionalized cellulose esters. As a proof of concept, cellulose acetate was acylated with two terminally olefinic acid ...
    • Ruthenium(ii)-polypyridyl zirconium(iv) metal-organic frameworks as a new class of sensitized solar cells 

      Maza, William A.; Haring, Andrew J.; Ahrenholtz, Spencer Rae; Epley, Charity Cherie; Lin, Shaoyang; Morris, Amanda (The Royal Society of Chemistry, 2015-10-16)
      A series of Ru(II)L2L′ (L = 2,2′-bipyridyl, L′ = 2,2′-bipyridine-5,5′-dicarboxylic acid), RuDCBPY, -containing zirconium(IV) coordination polymer thin films have been prepared as sensitizing materials for solar cell ...
    • Upconverting nanocomposites dispersed in urea-containing acrylics 

      Inglefield, David Lott, Jr.; Merritt, Travis R.; Magill, Brenden A.; Long, Timothy E.; Khodaparast, Giti A. (The Royal Society of Chemistry, 2015-05-08)
