Jeremy & friends’ paper, “Reactive Cross-Talk Between Adjacent Tension-Trapped Transition States” has been published in J. Amer. Chem. Soc. Congratulations to all involved!
A podcast describing our observation of “molecular stress relief” through covalent mechanochemistry in single polymer chains has been published online by J. Am. Chem. Soc. on their JACS(beta) platform. The complete podcast can be viewed here.
Congratulations to Ashley, whose paper “Mechanochemically Triggered Bond Formation in Solid-state Polymers” has been published in J. Mater. Chem. The paper is the result of a collaboration with Josh Orlicki at the Army Research Lab. The paper reports that the 2,3-dibromoalkene formed from mechanical activation of gem-dibromocyclopropane mechanophores undergo subsequent nucleophilic substitution by chloride in the solid state. The number of solid-state substitution reactions far exceeds the number of main-chain bonds broken, a finding with implications for the future use of mechanophores in self-strengthening and/or self-healing polymers.
Jeremy, Ashley, and co-workers have characterized the mechanically active domains in mechanophore-laden polybutadiene in the solid state. The paper has been published in J. Mater. Chem.
Congratulations to Jeremy Lenhardt, along with James Ogle and undergrad Robert Choe, on the acceptance of their communication “Reactive Cross-talk Between Adjacent Tension-Trapped Transition States” at J. Am. Chem. Soc.
Congratulations to Jeremy and Katie, who welcomed baby Charlotte Coco Lenhardt to their family (and the world) on Monday, January 24!
