Abstract: Protonation-triggered conformational changes of meso-octakis(pentafluorophenyl) [36]octaphyrin and [38]octaphyrin are examined. The absorption/fluorescence, excited singlet/triplet state lifetimes and two-photon absorption cross-section values are described for both protonated [36] and [38]octaphyrins in conjunction with their Mobius or Huckel aromaticity.
