多酸化学历史悠久。作为多核化合物中的一类，由于它们在水中良好的溶解性，多酸被视为可溶解的氧化物半导体的模型，而一直为人们所重视。近十多年来，多酸化合物已由单一的合成、性质研究逐步转向功能化合物的开发阶段，一系列的化合物在抗病毒、均相催化、探针分析等领域得? Multi-acid chemistry has a long history. As a class of polynuclear compounds, polyacids have been regarded as models of soluble oxide semiconductors due to their good solubility in water, and have drawn considerable attention. In recent ten years, polyacid compounds have been gradually turned to the development of functional compounds from a single synthesis and property research. A series of compounds have been developed in the fields of antiviral, homogeneous catalysis and probe analysis.
