Abstract
AbstractPorphyrin ion pairs, the charge of which is delocalized in core units, form tightly associated structures through iπ–iπ interactions. 5,10,15‐Triphenyl‐substituted porphyrin–AuIII complex, which is favorable for forming stacked structures in the form of a stable ion, has been synthesized. Ion‐pair metathesis based on the hard and soft acids and bases theory enabled combination with porphyrin anions possessing electronic states controlled by electron‐donating and electron‐withdrawing groups. Transient absorption spectroscopy suggested that the lifetimes of the radical pairs generated by photoinduced electron transfer of the ion pairs could be controlled by a judicious combination of the anions and cations.
