Robert R. Knowles

Robert R. Knowles is the Henry W. Putnam Professor of Chemistry at Princeton University, where he leads a research group focused on proton-coupled electron transfer (PCET) and light-driven catalytic transformations. His work bridges organic synthesis, photoredox chemistry, and asymmetric catalysis, with applications in pharmaceutical synthesis, polymer recycling, and sustainable chemistry.

• Research Highlights
  • Pioneering PCET mechanisms for homolytic bond activation
  • Developing enantioselective radical transformations
  • Innovating contrathermodynamic photochemical reactions
  • Advancing light-driven chemical recycling of thermosets

Recent trends in publications include asymmetric catalysis with radical intermediates, photoredox-driven C–H functionalization, and contrathermodynamic isomerization reactions. His group frequently employs visible light and chiral hydrogen-bonding catalysts to achieve unprecedented reactivity.
