    • The decay measured at the wavelength of K* phosphorescence has a minor additional long-lived component lasting to the millisecond time scale, speculated to come from a small contribution of impurities. We repeated the measurements and found that the contribution of this longlived component varied depending on sample preparation. In addition, a MeOPI-Ac solution showed a phosphorescence band with a peak wavelength of 530 nm. Because our samples were kept in the metallic reservoir of the cryostat for temperature-dependent measurements, the samples seemed to undergo a side reaction to give impurities having a molecular structure similar to that of the E form of HPI-Ac during cooling processes
