Zirconium-based metal-organic frameworks (Zr-MOFs) have received great attention due to their abundant structural diversity and controllable functionalizations. However, pentacarboxylic acid-based Zr-MOFs are less studied. Herein, we report a new pentacarboxylic acid-based organic linker, 4″,4‴″,4‴‴″-((4-(4,5-bis(4-carboxyphenyl)-1-imidazol-2-yl)phenyl)methanetriyl)tris(([1,1':4',1″-terphenyl]-4-carboxylic acid)), which has been successfully employed to construct a Zr-MOF, HIAM-4055 (HIAM = Hoffmann Institute of Advanced Materials). HIAM-4055 features a rarely reported (5,10)-c underlying net. Nanosized HIAM-4055 can be used as a chemical sensor for dichromate detection in aqueous solution with high stability and excellent sensitivity and selectivity.
