Abstract
En 中文
Covalent organic frameworks (COFs) have attracted extensive attention because of their structural tunability and ordered porosity. However, the strong inter-layer π–π stacking interactions in conventional COFs often lead to notorious aggregation-caused quenching (ACQ), which severely limits their luminescence-related applications. The incorporation of aggregation-induced emission (AIE) units into COFs has enabled the effective integration of porous structures with efficient aggregate-state luminescence. Consequently, AIE-COFs have emerged as a rapidly growing research focus in recent years. This review summarizes the commonly used linkage chemistries and construction strategies of AIE-COFs reported over the past five years. Particular emphasis is placed on their outstanding performance and application potential in diverse fields, including fluorescent sensing (gases, biomolecules, and ions), biomedical applications (bioimaging, photodynamic therapy, photothermal therapy, and ferroptosis/pyroptosis regulation), stimuli-responsive luminescent materials, and optoelectronic devices. Moreover, perspectives on the future development direction of AIE-COFs are also discussed.
