a Temperature-dependent steady-state fluorescence spectra of PBIs crystalline films (heating from 80 K to 300 K, λex = 480 nm). b Temperature dependence of 0–0 emission peak energy (Supplementary Figs. 23a–25a) and the Gaussian energetic disorder calculated according to the slopes at each extreme along with the temperature-dependent fluorescence spectra.
