聚合物与多金属氧酸盐簇杂化的先进功能材料：合成、组装和应用

In this work we target to develop a class of advanced functional materials based on polyoxometalate-polymer hybrids having polymer processability and the functions of polyoxometalate (POM) clusters. To improve, to a greater extent, the function and performance of hybrid materials, it is needed to realize hybridization between POMs and polymers at the molecular level by covalently linking them together. In this way they complement in function and performance each other perfectly, thus creating synergistic effect makes the comprehensive function and performance of hybrids much better than the raw materials. Consequently, these hybrids with new functionalities may meet the requirements of the rapid development of the technology for new functional materials. To achieve this goal, we should rationally design and precisely synthesize hybrids and then study their physical properties and structures. After clarifying the relationship between molecular and supramolecular structures and functions of the hybrids, their function and performance could be maximized. This study will focus on the following functions: (1) Biocompatibility: to explore the possibility of biocompatible polymer functionalized hybrids as a drug or biological material application; (2) Proton conductivity: To explore the possibility of protonated POM hybrid as a proton conductor applications; (3) Catalytic function: To prepare porous hybrid materials for POM hybrid polymer used as POM-containing heterogeneous catalysts. Our hope is that the hybrid materials developed can help urgently solve some major problems, for example, diseases, such as cancer, fuel cell and fuel desulfurization.

我们的目的是通过基础研究发展一类多金属氧酸盐(POM)与聚合物杂化的先进功能材料，使其具有POM的功能和聚合物的可加工性能。为了更大程度上提升材料的性能和功能，需要将POM和聚合物通过共价键实现分子级杂化，促成在性能上互相取长补短，产生协同效应，使其综合性能优于原组成材料，甚至展现新的特性，满足正在快速发展的科技对新材料的要求。要实现这一目标，就要从杂化材料的分子设计、合成、结构和物性的研究入手，阐明分子结构、超分子结构和功能之间的关系，实现功能的最大化。本研究将关注杂化物的功能有（1）生物相容性：探索杂化物作为药物或者生物材料应用的可能性；（2）质子传导性：探索POM质子化后杂化物作为质子导体应用的可能性；（3）催化功能：制备POM－聚合物杂化的多孔杂化材料，研究POM异相催化剂的催化功能。希望发展的杂化材料能够帮助解决社会迫切需要解决的重大问题，比如癌症等疾病、燃料电池和燃油脱硫。
