Abstract The growing scarcity of freshwater, driven by climate change and pollution, necessitates the development efficient sustainable desalination technologies. Solar‐powered interfacial water evaporation has emerged as a promising solution; however, its practical implementation is hindered limited availability stable photothermal materials. Herein, bandgap engineering strategy via linker modification to enhance conversion capability metal‐organic frameworks (MOFs) reported toward solar‐driven desalination. By systematically introducing functional groups with varying electron‐donating electron‐withdrawing abilities, energy UiO–66–X (X = ─F, ─H, ─OH, ─NH 2 , ─(NH ) finely tuned. Density theory (DFT) calculations femtosecond transient absorption (fs–TA) spectroscopy reveal that stronger narrow MOFs, thereby improving their efficiency. optimized UiO–66–(NH material reaches peak surface temperature 58.7 °C when exposed simulated sunlight at ≈1 kW·m −2 efficiency 86.50% an rate 2.34 kg·m ·h −1 97.40%. This study presents novel approach for fine‐tuning in materials, offering pathway advanced solar technologies address global crisis.
