The proposal represents an important effort of enriching the specific area of metal-oxide based materials and nanoscience. New types of Keplerate capsules should be synthesized in the sense to modify the hydrophilic, spherical nanocapsules ({Mo132}, {Mo72W60} and their derivatives such as {Mo72Fe30}, {Mo72Cr30}, {Mo72V30}, {W72Fe30} and {W72V30}) in order to change their charge densities and to control the properties of the nanopores. Solution physical chemistry studies will be performed on such unique systems by the American PI, in order to understand the cation distribution around the nanocapsules and its change in response to the changes of the environment, the cation replacement and sequesterization around capsules, the transportation of cations through self-assembled porous “membranes”, and the nature of the molecular recognition among the anionic nanocapsules forming thereby vesicles. Related properties of the other mentioned molybdenum oxide nanoobjects should be also investigated. The project can only be successfully accomplished by close collaborations between the German PI (specialized in the present context in the syntheses of inorganic clusters) and the American PI (specialized in solution physical chemistry, especially POM solutions).

该提案代表了丰富金属氧化物基材料和纳米科学特定领域的重要努力。应合成新型Keplerate胶囊，以修饰亲水性球形纳米胶囊（{Mo 132}、{Mo 72 W 60}及其衍生物，如{Mo 72 Fe 30}、{Mo 72 Cr 30}、{Mo 72 V 30}、{W 72 Fe 30}和{W 72 V 30}），从而改变它们的电荷密度并控制纳米孔的性质。美国PI将对这种独特的体系进行溶液物理化学研究，以了解纳米胶囊周围的阳离子分布及其响应环境变化的变化，胶囊周围的阳离子置换和螯合，阳离子通过自组装多孔“膜”的运输，以及由此形成囊泡的阴离子纳米胶囊之间的分子识别性质。还应该研究其他提到的氧化钼纳米物体的相关性质。该项目只能通过德国PI（专门从事无机簇合物的合成）和美国PI（专门从事溶液物理化学，特别是POM溶液）之间的密切合作才能成功完成。
