Abstract
© The Royal Society of Chemistry.Force reactive functional groups, or mechanophores, have emerged as the basis of a potential strategy for sensing and countering stress-induced material failure. The general utility of this strategy is limited, however, because the levels of mechanophore activation in the bulk are typically low and observed only under large, typically irreversible strains. Strategies that enhance activation are therefore quite useful. Molecular-level design principles by which to engineer enhanced mechanophore activity are reviewed, with an emphasis on quantitative structure-activity studies determined for a family of gem-dihalocyclopropane mechanophores.

Research interests in Prof. Craig's group bridge physical organic and materials chemistry. Many of these interests are guided by the vision that important challenges in materials science might be better tackled not from the traditional perspective of an engineer, but rather from the molecular perspective of an organic chemist. Current interests include the design and synthesis of self-healing polymers and the use of modern mechanochemistry in new stress-responsive polymers, catalysis, and the study of transition states and reactive intermediates. These areas require an interdisciplinary and nontraditional mix of synthetic organic and polymer chemistry, single-molecule spectroscopy, supramolecular chemistry, and materials characterization. Research interests are complemented by numerous teaching and outreach activities, including: (1) hosting intensive undergraduate and high school research experiences for a diverse group of both Duke and non-Duke students; (2) exploiting effective, scalable, and low-cost mechanisms for content dissemination; (3) team-based and active learning content in the undergraduate and graduate classroom.
