Abstract Hydrogen‐bonded organic frameworks (HOFs), a novel subclass of porous crystalline materials self‐assembled from organic linkers through hydrogen bonding and other intermolecular interactions, have emerged as an exciting platform for developing multifunctional materials. Recently, luminescent HOF sensors have drawn considerable attention due to their unique advantages, such as hydrogen‐bonding flexibility, inherent luminescent centers in organic linkers, ease of functionalization, low density and toxicity, and good stability. However, a comprehensive study on the design strategies, functionalities, and applications of HOFs in sensing is lacking. In this review, the uniqueness and development of luminescent sensing HOFs are outlined. The design principles and strategies to enable the sensing performance are summarized, including the pre‐design of luminescent organic linkers and post‐modification with additional luminescent species. The state‐of‐the‐art advances in diverse sensing applications are overviewed, such as the detection of chemical pollutants, biomolecules, gases, and physical factors like temperature and mechanical forces. Moreover, the current challenges and corresponding potential avenues are discussed. This review aims to inspire more innovative research on the fabrication of advanced HOFs for luminescent sensing functions.
