<p>Chemical sensing technology is pivotal in modern industry and daily life, with sensor performance critically reliant on nanomaterials. While sensors based on traditional nanomaterials, such as inorganic semiconductors and organic conductive polymers, have achieved commercialization, they face persistent challenges. As an emerging subclass, conductive metal-organic frameworks (c-MOFs) not only inherit the core advantages of traditional MOFs, high specific surface area, porosity, and tunable composition/structure, but also offer adjustable electrical conductivity, rendering them ideal for sensing applications. This review systematically elucidates the construction and properties of c-MOFs across microscopic crystalline and macroscopic micro-nano structural scales. Special emphasis is placed on the structural design and regulation of c-MOFs for analytical sensing, and the intrinsic structure-performance relationship is clarified to achieve higher sensitivity, selectivity, response speed, and long-term stability, as well as other performance. Finally, we comprehensively summarize the typical applications of c-MOFs-based sensors, covering environmental and safety monitoring, photoelectric detection, and health monitoring and diagnosis. At the same time, the key challenges existing in this field, such as the controllable preparation of high-quality single-crystal materials, the theoretical analysis of intrinsic electrically conductive mechanisms, and the balance between the macroscopic material stability and the processing performance of devices, were evaluated. The future research directions should focus on developing new ligands and metal combinations to optimize the band structure, deepening the exploration of the mechanisms of emerging physical effects such as piezoelectricity, and promoting the integration and application of materials in practical scenarios such as flexible electronics and wearable devices.</p>
