Polyoxometalates (POMs) are anionic metal-oxide clusters with diverse sizes and shapes. Because of their remarkable redox behavior and excellent affinity, they are often used as a multifunctional inorganic polydentate ligands. POMs can effectively combine various metal ions and organic ligands to synthesize porous materials with better structure and function. 1,3,5-benzene-tricarboxylic acid (BTC) is an oxygen-containing ligand with three symmetrically arranged carboxylic acid groups forming rigid planar connectors. Due to its high reactivity and multiple coordination modes, it is easy to modify and functionalize the POMs. Many studies have been carried out on BTC modified POMs. This review summarizes and compares the advantages and disadvantages of various synthesis methods of POMs modified by BTC, and summarizes the applications of synthetic compounds in different fields. In fact, there are four combinations between BTC and various POMs. BTC can not only be used as a template to support polymolybdate, but also form a large class of M−BTC to further modify POMs to form a large class of POM@M−BTC. POM@M−BTC not only combines their advantages, but also overcomes defects of POMs instability and achieves maximum material functionalization in many fields, which is the direction of future development. Therefore, the design and exploration of compounds based on BTC modified POMs are still the most compelling and challenging fields in POM chemistry.

多金属氧酸盐 (POM) 是具有不同大小和形状的阴离子金属氧化物簇。由于其显着的氧化还原行为和优异的亲和力，它们常被用作多功能无机多齿配体。POMs可以有效结合多种金属离子和有机配体，合成具有更好结构和功能的多孔材料。1,3,5-苯三羧酸 (BTC) 是一种含氧配体，具有三个对称排列的羧酸基团，形成刚性平面连接器。由于其高反应性和多种协调模式，很容易修改和功能化 POM。已经对 BTC 改性 POM 进行了许多研究。本综述总结并比较了BTC改性POMs的各种合成方法的优缺点，并总结了合成化合物在不同领域的应用。事实上，BTC 和各种 POM 之间有四种组合。BTC不仅可以作为支持多钼酸盐的模板，还可以形成一大类M−BTC进一步修饰POMs形成一大类POM@M−BTC。POM@M−BTC不仅结合了它们的优点，而且克服了POM不稳定的缺陷，在很多领域实现了材料功能化最大化，是未来发展的方向。因此，基于 BTC 改性 POM 的化合物的设计和探索仍然是 POM 化学中最引人注目和最具挑战性的领域。但也形成一大类 M−BTC 进一步修改 POM 形成一大类 POM@M−BTC。POM@M−BTC不仅结合了它们的优点，而且克服了POM不稳定的缺陷，在很多领域实现了材料功能化最大化，是未来发展的方向。因此，基于BTC改性聚甲醛的化合物的设计和探索仍然是聚甲醛化学中最引人注目和最具挑战性的领域。但也形成一大类 M−BTC 进一步修改 POM 形成一大类 POM@M−BTC。POM@M−BTC不仅结合了它们的优点，而且克服了POM不稳定的缺陷，在很多领域实现了材料功能化最大化，是未来发展的方向。因此，基于BTC改性聚甲醛的化合物的设计和探索仍然是聚甲醛化学中最引人注目和最具挑战性的领域。
