To study the photoexcitation and subsequent reactions of large molecular ions, anions of 5,10,15,20-tetraphenyl-21H,23H-porphine, which is a typical metal-free porphyrin, were produced and stored in an electrostatic ion storage ring at the Tokyo Metropolitan University. The circulating ions were merged using a pulsed laser, resulting in the production of super-excited anions, which eventually yielded neutral species. The decay profile deviated considerably from t-1 behavior, depending on the laser fluence and excitation wavelength.
