Professor Tianbo Liu of Lehigh University is supported by the Macromolecular, Supramolecular and Nanochemistry Program in the Division of Chemistry for an International Collaboration in Chemistry (ICC) grant to develop rational methods for the synthesis of new type of nanoporous molecular capsules and investigate their complex interaction with counterions. Polyoxometalate clusters with specific surface functionalities of the crown-ether type and a variety of porous Keplerate nanocapsules with tunable pore sizes and charges will be synthesized. The new capsules will be used as model systems to explore their interactions with small counter-ions, counter-ion exchange and replacement, counter-ion transport over the membranes of Keplerate assemblies, and the nature of the surface water ligands on the capsules. This work includes an international collaboration with Professor Achim Müller of the University of Bielefeld (Germany). Professor Müller's work is supported by the Deutsche Forschungsgemeinschaft German Research Foundation (DFG) of Germany.This research will provide important knowledge for the design and preparation of new materials with catalytic, electronic, and magnetic properties. The capsules synthesized may also serve as models for biological and bio-mimetic processes. This project will, therefore, impact diverse areas (including chemistry, biological science, and materials science). Furthermore, this international collaboration provides unique research environments for training students and postdoctoral researchers.

理海大学刘天波教授获得化学系高分子、超分子和纳米化学项目国际化学合作（ICC）资助，开发合成新型纳米多孔分子胶囊的合理方法并研究其复杂的相互作用具有抗衡离子的多金属氧酸盐簇，具有冠醚型的特定表面官能团和各种具有可调孔径和电荷的多孔开普勒酸盐纳米胶囊。新的胶囊将被用作模型系统，以探索它们与小反离子的相互作用、反离子交换和替换、反离子在 Keprate 组件膜上的传输以及表面水配体的性质。这项工作包括与比勒费尔德大学的 Achim Müller 教授（德国）的国际合作，并得到了 Deutsche Forschungsgemeinschaft 德国研究基金会的支持。这项研究将为具有催化、电子和磁性的新材料的设计和制备提供重要的知识，因此，该项目也可以作为生物和仿生过程的模型。 ，影响不同的领域（包括化学、生物科学和材料科学）此外，这种国际合作为培训学生和博士后研究人员提供了独特的研究环境。
