Structure-Property Relationships Based on Inorganic-Organic Host-Guest Assemblies

这份题为“基于无机-有机主-客体组装体的结构-性质关系”的提案的目的是解决通过包合化学获得的新型纳米材料的合成和制造、表征和结构-性质关系。将要研究的系统将包括层状硅酸盐，如硅长石和蒙脱土，嵌层有苯胺、噻吩和吡罗等，然后通过粉末x射线衍射、扫描力显微镜、差示扫描量热法、电子自旋共振和阻抗谱进行表征。将研究混合材料的内部结构，并探讨结构与观察到的性能（如导电性、磁性、光学响应和化学传感）之间的协同作用。非共价主-客和客-客相互作用的作用将被描述，以及用于合成和优化其他新材料的知识。有机和无机分子单元集成到复合纳米结构中，为新型结构和性能设计提供了许多可能性。这些类型的纳米结构材料的设计和表征是一个年轻的领域，为设计传感器、分子筛、分离介质和催化剂等功能材料提供了令人兴奋的可能性。＊＊＊

Systems to be studied will include layered silicates such as hectorite and montmorillonite intercalated with aniline, thiophene, and pyrrole guests in the intergallery region of the smectic clays, followed by characterization by powder x- ray diffraction, scanning force microscopy, differential scanning calorimetry, electron spin resonance, and impedance spectroscopy. The inner arictecture of the hybrid materials will be studied, and the synergism between architecture and observed properties such as conductivity, magnetism, optical response, and chemical sensing will be probed. The role of non-covalent host-guest and guest-guest interactions will be delineated, and the knowledge used to synthesize and optimize other novel materials. %%% The integration of organic and inorganic molecular units into composite nanostructures provides many possibilities with respect to both novel structures and property design. The design and characterization of these types of nanostructured materials is a young field of endeavor that presents exciting possibilities for designing functional materials for applications such as sensors, molecular sieves, separations media, and catalysts. ***
