Design of the guest/host system. a Schematic illustration of the guest/host system, i.e., solid-state solutions where guest is the solute and host is the solvent, showing UV/mechano-excited ultralong room temperature phosphorescence (URTP). FL: fluorescence. b Compound structures studied in this work. Abbreviations: PCP for pentachloropyridine, PA for phthalic anhydride, DCB for 1,2-dicyanobenzene and NA for 1,8-naphthalic anhydride
