| Abstract(in English) | There has been intense interest in pure organic room-temperature phosphorescence (ORTP) from cocrystals composed of 1,4-diiodotetrafluorobenzene (DITFB) and a variety of polyaromatic hydrocarbons (PAHs) or their derivatives. To expand the possibility of halogen bonding-based cocrystals, we investigate the relationship between the crystal packing motifs and ORTP characteristics in binary cocrystals composed of DITFB and PAHs of phenanthrene (Phen), chrysene (Chry), and pyrene (Pyr), respectively. The ?-hole???? and ?-hole???? interactions determine not only the crystal packing motifs but also photoluminescence quantum yields (PLQYs). Based on these results, ternary cocrystals are fabricated and realize more than 20% PLQY as a result of suppressing nonradiative decay by changing the crystal packing motif. |
