Abstract

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)-1H-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 fit 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.

具有10连接Zr6簇的发光锆-五羧酸盐框架用于重铬酸盐检测。

锆基金属有机骨架（Zr-MOFs）因其丰富的结构多样性和可控的功能化而受到广泛关注。然而，基于五羧酸的Zr-MOFs研究较少。在此，我们报道了一种新的五羧酸基有机连接剂，4″，4 ″，4 -″-（（4-（4,5-双（4-羧基苯基）- 1h -咪唑-2-基）苯基）甲三基）三（（[1,1':4'，1″-terphenyl]-4-羧基）），已成功用于构建Zr-MOF， HIAM-4055 （HIAM = Hoffmann Advanced Materials Institute）。HIAM-4055具有很少报道的(5,10)-c拟合底层网络。纳米级的HIAM-4055具有较高的稳定性和良好的灵敏度和选择性，可作为水溶液中重铬酸盐检测的化学传感器。
