摘要/Abstract
方便地合成了三个含有卤素取代邻苯二甲酰亚胺与咔唑基团的新型有机发光材料Br-Al-Cz，Cl-Al-Cz和F-AI-Cz，发现它们不仅具有强的聚集诱导发光效应，而且显示膜态下热激活延迟荧光以及晶态诱导的室温磷光性质.尤其是化合物Br-Al-Cz表现出肉眼可见的长余辉室温磷光现象，因此在数据加密等中具有潜在用途.

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
