Optical and magnetic tweezers and scanning-probe microscopes are being used to study how molecules react under mechanical force. The methodology relies upon the complementarity between the π-electron-deficient and the π-electron-rich macrocyclic components. An early report by Ho, Stoddart, Houk and co-workers Stoddart’s Mechanochemistry Group Lab at Northwestern University spent years with preparing and investigating multicomponent non-covalent superstructures, so-called metal-organic-frameworks (MOF). Motivated by the desire to create novel (nano)materials that exhibit currently unavailable properties and enable new applications, the primary research focus of the Polymer Chemistry and Materials group is the design, synthesis, and investigation of structure-property relationships of novel functional polymers. He obtained his BS degree in chemistry from Peking University, where he worked on synthesizing organic molecular sensors and mechanochemistry-related topics under the supervision of Prof. Yuguo Ma. Earlier this year, Lodi Police Chief Tod Patterson retired from his post after 33 years in law enforcement, and now his counterpart in the fire department will be following in his footsteps. The latter indicates that polymer mechanochemistry follows its own set of rules that, however, regarding underlying mechanisms and design rationales is far from being holistically understood. In the summer of 2012, he joined Northwestern University to pursue his PhD in chemistry within the research group of Sir Fraser Stoddart. The time has come for another periodic table group picture! Mechanochemistry isn’t just about shaking vessels violently or crushing reactants between huge screws, there are some researchers in this field taking a much gentler approach. Mechanochemistry. The group is interested in design and synthesis of new mechanophores that transduce mechanical input into chemical stimuli: e.g., mechanically-triggered depolymerization of metastable polymers to enhance recyclability of materials, generation of protons under force, and recently generation of light. Similar structures were reported by Fujita’s group in which the formation of a Pt-based supramolecular square took more than four weeks at 100 °C. It has been known for decades that breaking high molecular weight polymeric materials often involves the scission of carbon-carbon bonds. Their pioneering work has resulted in numerous seminal papers … Stoddart Group (Roofing Company): 1.6 out of 5 stars from 22 genuine reviews on Australia's largest opinion site ProductReview.com.au. One absent in the picture: Richard Stevenson. We welcome 5 new members in the group: Dr Paramita Das (PDRA), Lei Chen (PhD), Kamil Suwada (PhD), Jacob Kenyon (iCat CDT rotation), Sarah Kaye (MChem), and Elliott Nunn (MChem). Welcome all! Website of the Centre for Mechanochemical Cell Biology. Traction control. A series of mono- and difunctionalized [2]catenanes, incorporating a bipyridinium-based cyclophane component interlocked with a dioxyarene-based macrocyclic polyether, have been self-assembled.
