Yellow phosphorescence emission of 1,8-naphthalimide guest was activated by doping it into m-bromobenzaldehyde host (energy transfer mechanism). With the aim alleviating triplet-triplet annihilation benzaldehyde itself, m-dibromobenzene introduced as third component. As a result, quantum yields doped crystallized materials significantly increase from 1.72% for NI@mBA to 19.17% NI@mBA@mDBB (with 11 times enhancement) due cascade activation in three-component system. The encryption/decryption using these phosphorescent provides potential application security field. This study not only expands scope organic molecules capable activating properties NI, but also platform developing multi-component systems that can effectively regulate properties.
