Cover Picture: The increasing accumulation of polyethylene terephthalate (PET) waste poses significant environmental challenges due to its complex composition and difficulty in recycling. Metal-organic frameworks (MOFs) derived from PET have emerged as a promising solution, offering high porosity, tunable chemistry, and versatile functionality for various applications. This review comprehensively summarizes recent progress in the synthesis of PET-derived MOFs, including two-step, one-pot, mechanochemical, microwave-assisted, and in situ growth strategies, with particular attention to the conversion of complex waste PET feedstocks. The applications of PET-derived MOFs are then reorganized into adsorption and separation, catalysis, energy storage and conversion, sensing and detection, and emerging functional applications. Particular emphasis is placed on CO2 capture and gas separation, wastewater purification, pollutant degradation, electrochemical energy storage, molecular sensing, flame protection, passive thermal management, and functional composite materials. By integrating insights into synthesis, structure-property relationships, and functional applications, this review also highlights the potential of PET-derived MOFs as sustainable materials for next-generation energy and environmental technologies, bridging the gap between polymer waste recycling and advanced material design.
