Metal–organic frameworks with aggregation‐induced emission

Abstract

Aggregation‐induced emission (AIE) materials exhibit remarkable emission in the aggregated or solid state while demonstrating minimal emission in dilute solutions. In contrast to conventional luminescent materials, AIE luminogens (AIEgens) offer several advantages in the aggregate state, including high quantum yield, excellent photostability, and low background signals, making them highly promising for diverse applications. Integrating AIEgens into designable metal–organic frameworks (MOFs) enables tunable and well‐ordered AIE materials, allowing for precise control over photophysical properties and deeper exploration of AIE mechanisms. Numerous AIE MOFs have been constructed and investigated, and several reviews focus on their structure design and applications in sensing and bioimaging. This review highlights the state‐of‐the‐art advancements in AIE MOFs, including mechanisms, design strategies, and applications in chemical sensing, bioimaging, and disease therapy. The challenges associated with practical applications of AIE MOFs are also addressed, with an emphasis on their large‐scale production involved interdisciplinary collaboration. This comprehensive review aims at guiding further development of AIE MOFs and promoting their practical applications in analysis, healthcare, and other luminescence related fields.

Two AIE-Ligand-Based 2-D Luminescent Metal–Organic Frameworks as Fe3+ Sensors

“…Metal–organic frameworks (MOFs) as advanced solid materials have garnered significant attention for their versatile applications. − Constructed through the assembly of organic ligands and inorganic metallic cations or clusters, MOFs display predesigned porous architectures with high surface area, good stability, target-specific host–guest interaction, and functional diversity. − MOFs are extensively utilized as luminescent sensor materials for diverse purposes. They offer notable benefits in terms of sample preparation and detection efficiency. , Luminescent MOFs (LMOFs) can recognize metallic ions through the luminescence “turn on” or “turn off” mechanism.…”
