New Zr IV ‐ and Hf IV ‐based metal–organic framework photocatalysts, termed VNU‐1 and VNU‐2 (where VNU=Vietnam National University), were synthesized and their resulting structures fully characterized. By employing a highly π‐conjugated linker, namely 1,4‐bis(2‐[4‐carboxyphenyl]ethynyl)benzene, the optical absorption properties were effectively red‐shifted into the visible light region. This strategy, coupled with the high water stability of the materials, led to enhanced MOF‐driven photocatalytic degradation, under ultraviolet‐visible light, of organic dye pollutants commonly found in wastewater.
