Description:Seminar Abstract:\nIron complexes are promising alternatives to
  precious-metal photosensitizers\, but rapid excited-state relaxation ofte
 n limits their reactivity. This seminar will discuss a recent study that c
 ombines ligand design and organization within micelles to promote electron
  transfer from a short-lived upper excited state of an iron(II) complex. S
 pectroscopic and electrochemical evidence for this pathway will be examine
 d\, along with the limitations of the proposed mechanism. The study highli
 ghts how both excited-state energy and reaction kinetics determine whether
  absorbed light can drive a chemical reaction.\n\n\nReference:\nGhosh\, A.
