a UV-vis absorption spectra and PL spectra of (R)-OBN-XT-SXAC and (R)-OBN-XT-SFAC in toluene solutions (1 × 10‒5 M). b PL spectra of (R)-OBN-XT-SXAC and (R)-OBN-XT-SFAC in neat films and doped films (20 wt% in PPF). c Temperature-dependent transient PL decay spectra of (R)-OBN-XT-SXAC in neat film, measured under nitrogen. d CD spectra of (R/S)-OBN-XT-SXAC and (R/S)-OBN-XT-SFAC in toluene solutions (1 × 10‒4 M). CPL spectra of (R/S)-OBN-XT-SXAC and (R/S)-OBN-XT-SFAC in (e) neat films and (f) doped films (20 wt% in PPF). g gPL values of (R/S)-OBN-XT-SXAC and (R/S)-OBN-XT-SFAC at their related PL peaks in toluene solutions (1.0 × 10−4 M), neat films and doped films (20 wt% in PPF). Plots of gPL versus PL wavelength of (R/S)-OBN-XT-SXAC and (R/S)-OBN-XT-SFAC in (h) neat films and (i) doped films (20 wt% in PPF).
