a Molecular structures of perylenemonoimide dye-modified DAEs (PMI-1DAE, PMI-2DAE, and PMI-3DAE). b Table of optical properties of PMI-1DAE, PMI-2DAE, and PMI-3DAE in toluene. c The polynomial fitting of the fluorescence quenching efficiency Q(t) versus photoconversion yield α(t). The inset is the calculated fluorescence quenching ratio Rcal = 1/[1 − α(t)]n. The concentration is 1.0 × 10−6 M in toluene. (Reprinted with permission from Li et al.37.
