Photoelectrochemical C-N bond formations with novel, tunable triarylamines that engage substrates via dispersion precomplexation, hot off the press!🗞️✨ WARNING ⚠️*topics presented (contra-redox potential, contra-Kasha rule) are highly controversial - proceed with caution*⚠️ 😎👇.
Introducing triarylamines, tunable #electrochem⚡️activated photocats for super-oxidations. We discovered pi-stacking precomplexation 1) rationalizes photochem💡of ps-lived⏱️*[radical ions] & 2) harnesses full power of vis. photons by anti-Kasha #photochem!
