A new kind of organic luminescent materials containing halogen-substituted phthalimide group and carbazole subunit have been conveniently synthesized. They not only showed strong aggregation-induced emission (AIE) effect, but also exhibited thermally activated delayed fluorescence (TADF) in films and crystallization-induced room-temperature phosphorescence (RTP) properties. Especially, RTP with marked afterglow for Br-AI-Cz was observed by naked eye, which could be used as the promising smart materials for the encryption application.

Key words: organic luminescent material, room-temperature phosphorescence, thermally activated delayed fluorescence, aggregation-induced emission, phthalimide
