DESCRIPTION:Light-Driven Sustainable Chemistry\n\nPhoton-driven processes h
 ave become a powerful tool for achieving challenging bond cleavages and fo
 rmations. Photocatalysis offers temporal and spatial control with low-ener
 gy light\, which has been widely advantageous for efficiently building mol
 ecular complexity from simple starting materials. The judicious choice of 
 photocatalysts enables the precision of reactivity that is rarely achieved
  with other forms of catalysis and heating. An underused area of photocata
 lysis is light-to-heat (photothermal) conversion. Irradiation of specific 
 nanoparticles or dyes with visible light creates intense thermal gradients
  in a photothermal conversion process. In contrast to bulk heating\, where
  the temperature remains uniform across a reaction medium\, substrates wou
 ld only experience thermal energy within a few nanometers of excitation un
 der temporal heating. Consequently\, this process uses irradiation to driv
 e chemical processes at high temperatures with temporal and spatial contro
 l. I will show this phenomenon as applied to challenges such as chemical r
 ecycling to monomer\, broad-spectrum wavelength photocontrolled polymeriza
 tions\, intramolecular rearrangements\, and intermolecular coupling reacti
 ons.\n\n \n\nThis event is part of the Aggarwal Lecture Series
