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.

Lehigh University的Tianbo Liu教授得到了国际化学合作授予化学授予化学授予的巨大分子，超分子和纳米化学计划（ICC）赠款，以开发合理的方法，以相互结合新型的纳米型分子帽并研究其与柜台复杂的互动。将合成具有牙冠类型的特定表面功能和各种具有可调孔尺寸和电荷的多孔纳米胶囊的多氧盐簇。新的胶囊将用作模型系统，以探索其与小工具的相互作用，反离子交换和替换，对开plate组件机制上的反离子运输以及胶囊上的地表水配体的性质。这项工作包括与比勒菲尔德大学（德国）的AchimMüller教授的国际合作。穆勒教授的工作得到了德国德国德国德国研究基金会（DFG）的支持。这项研究将为设计和制备具有催化，电子和磁性的新材料提供重要知识。合成的胶囊也可以用作生物学和生物模拟过程的模型。因此，该项目将影响潜水区（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。
