  • Welcome to Caralina Crouch and Yasir Hamza

    We have two new graduate students joining the group! Caralina comes to us from the University of Dayton and will be working on our foldamers project. Yasir graduated from Jahangirnagar University and will be working on out-of-equilibrium polymer materials, co-supervised by Dominik Konkolewicz.

  • New paper in J. Org. Chem.

    We have a new paper out in J. Org. Chem.! Yinhui has figured out why o-phenylenes and 2,3-pyrazinylenes fold differently, work that was started by Govinda. Several undergraduates, Jacob, Sean, and Diamond, contributed to this project. We collaborated with Vipul Batra and Dave Tierney, who acquired the crystal structures.

  • New paper in Chem.—Eur. J.

    We have a new review out in Chem.—Eur. J.! Govinda and Roshan discuss the mechanisms by which an attached chirality center can influence the preferred configuration of an otherwise achiral, dynamic foldamer helix. This is not just a survey of the literature. We reevaluated many examples from the literature in order to establish general principles for understanding this process.

  • New paper in ChemSystemsChem

    We have a new paper out in ChemSystemsChem! Renu and Jackson have studied a simple carbodiimide-driven reaction network in the presence of various pyridine catalysts. This work provides useful guidance for designing these systems, and some unexpected results…

  • New paper in J. Chem. Educ.

    We have a new paper out in J. Chem. Educ.! Renu and Jackson developed an experiment for second-year organic chemistry teaching labs that uses NMR spectroscopy to probe the aggregation of caffeine in water.

  • Daniel Ryu joins group

    Welcome to Daniel Ryu, who has joined the group as an undergraduate researcher!

  • Welcome to Jacob Smith

    Welcome to Jacob Smith, who has joined the group as an NSF REU student! Jacob comes to us from Western Carolina University.

  • New publication in Chem­Systems­Chem

    We have a new paper out in ChemSystemsChem! In it, Chamoni reviews the uses of chemical fuel reactions in polymer materials, showing how they can effect transient changes in properties.
