ABSTRACT A mixed‐linker synthetic strategy was employed to engineer the morphology of copper–triazolate metal–organic frameworks (Cu‐Tz MOFs) through controlled crystal growth. By incorporating amino‐ and thioether‐functionalized triazole alongside the parent triazole linkers, the framework's hydrophilicity, pore cavity, and surface chemistry were systematically modulated. Upon thermal activation, the resulting mixed‐linker MOFs revealed accessible Cu(II) open metal sites, together with enhanced hydrophilicity and porosity within the framework. These features synergistically contribute to superior water removal performance from azeotropic water–ethanol mixtures, outperforming the parent CuTz in separation efficiency.
