Artificial Molecular Machines: Going from Solution to Surfaces

ACS Webinars

Featuring 2016 Nobel Laureate in Chemistry Sir Fraser Stoddart

The design and synthesis of artificial molecular machines (AMMs) with machine-like behavior, as it expressed at the nanoscale level, through the use of mechanically interlocked molecules (MIMs) opens the gates to unprecedented opportunities in many fields of science and technology, including the synthesis of sequence-controlled polymers and the release of cargoes (drugs) mechanisorbed on to flat two-dimensional surfaces and on to nanoparticles.

Join ACS President H.N. Cheng for “Frontier Fridays” a mini-series that explores new frontiers in science that will revolutionize the future of the human race. During this third free interactive broadcast, 2016 Nobel Laureate in Chemistry Sir Fraser Stoddart of Northwestern University will discuss his award winning research regarding artificial molecular machines as well as his current research regarding molecular pumps and motors working away-from-equilibrium on surfaces as well as in solution. Discover an introduction to the current state of the field as well as a look into the potential future it holds for not only chemistry, but also for the materials and medical sciences.

This ACS Webinar was moderated by Young-Shin Jun (Chair of Science & Technology Subcommittee of the ACS Committee on Science) of the Washington University in St. Louis. The “Frontier Fridays” Webinar Series are organized by ACS President H.N. Cheng, Michael Morello (Division Representative, ACS Committee on Science) Retired formerly PepsiCo R&D, Young-Shin Jun of Washington University in St. Louis, and Martin G. Kociolek (Chair of the ACS Committee on Science) of Penn State Behrend, and co-produced with the ACS Committee on Science.

What You Will Learn

  • How mechanically interlocked molecules (MIMs) are easily made and how they can be used inn the construction of artificial molecular machines (AMMs)
  • How AMMs operate under kinetic control using energy ratchets in a manner similar to that employed by our many biomotors and are at odds with how machines operate in the macroscopic world: the difference could not be more stark!
  • How redox and acid-base chemistry can be used to load and unload precisely a set of cargoes between a solution phase and solid-state supports
  • How metal-organic framework nanosheets and nanoparticles function like extended platforms, in addition to acting as coordinative organizers for arrays of artificial molecular pumps constructed of half dumbbells which can be threaded using pumping cassettes by multiple rings, one ring at a time and then all released at once on command
  • How, in addition to physisorption and chemisorption, a new concept - namely mechanisorption - is about to enter the lexicon of chemistry
