Abstract: Hydrogen-bonded organic frameworks (HOFs) are an emerging class of porous crystalline materials constructed through intermolecular hydrogen-bond self-assembly. Owing to their high crystallinity, structural tunability, dynamic reversibility, and facile functionalization, HOFs have shown considerable potential in gas adsorption and separation, chemical sensing, and optoelectronic functional materials. However, conventional organic luminophores often suffer from aggregation-caused quenching (ACQ) in the solid state, which limits their luminescent performance. Recently, incorporating aggregation-induced emission (AIE) characteristics into HOFs has emerged as an effective strategy to overcome ACQ. This review summarizes recent advances in AIE-active fluorescent and phosphorescent HOFs, focusing on their structural design, mechanisms, and applications, and briefly discusses current challenges and future perspectives.
