From: Isostructural doping for organic persistent mechanoluminescence

a Chemical structures of the isostructural host and guest molecules. b Normalized PL (steady state and delayed 10 ms) spectra of BCPC&b-BCPC, BCPC&c-BCPC, BCPSO&b-BCPC, and BCPSO&c-BCPC. c RPhos, ΦFluo, and ΦPhos for these four isostructural doping systems. d–g TRES of pML for BCPC&b-BCPC (d), BCPC&c-BCPC (e), BCPSO&b-BCPC (f), and BCPSO&c-BCPC (g). Inset: pML images of these four doping systems.
