DMR-0847535TECHNICAL SUMMARY:The project aims to develop novel nanostructured inorganic materials with programmable physical and chemical properties. The approach involves new chemistry for solution-based fabrication of inorganic functional materials from nanoscale building blocks. Specifically, functional nanostructured phases will be synthesized by combining colloidal inorganic nanomaterials (metal and semiconductor clusters, nanocrystals, nanowires, etc) and molecular metal chalcogenide complexes. Various molecular metal chalcogenide complexes, such as SnS44-, Sn2Se64-, In2Se42-, Ge4S104- will be used to completely replace original hydrocarbon surface ligands at the surface of colloidal metal and semiconductor nanostructures. After formation of a nanostructured assembly, new surface ligands will be converted into an inorganic solid, linking individual nano-building blocks into a macroscopic array of strongly electronically coupled functional modules. The project will combine the development of synthetic methodologies, detailed structural, electronic and optical characterizations of new materials and fabrication of prototype electronic and optoelectronic devices.NON-TECHNICAL SUMMARY:The project aims to develop a generalized methodology for preparation of nanostructured inorganic materials through ?modular? self-assembly of nanoscale functional building blocks. This approach may lead to a novel class of solution processed semiconductors for the applications ranging from solar cells to thermoelectric heat converters, light-emitting devices and printable electronics. The integration of research and educational components will generate broad outreach and educational activities including participation in the conceptual design and development of the Nanoscience exhibit for Chicago Museum of Science and Industry. The Museum attracts approximately 2 million visitors per year, nearly 280,000 children in school groups and youth organizations visited the Museum in 2007. Aimed at inspiring youth to consider education and careers in the physical and biological sciences, the objective of new exhibit is to convey the excitement of modern scientific research, its multidisciplinary nature, and the synergy between different areas of science and technology.

DMR-0847535技术概要：该项目旨在开发具有可编程物理和化学性质的新型纳米结构无机材料。该方法涉及利用纳米级构件以溶液为基础制造无机功能材料的新化学方法。具体来说，功能性纳米结构相将通过胶体无机纳米材料（金属和半导体簇、纳米晶体、纳米线等）与分子金属硫属化物配合物的结合来合成。各种分子金属硫族化物配合物，如SnS44-、Sn2Se64-、In2Se42-、Ge4S104-将用于完全取代胶体金属和半导体纳米结构表面原有的烃表面配体。形成纳米结构组件后，新的表面配体将转化为无机固体，将单个纳米构件连接成强电子耦合功能模块的宏观阵列。该项目将结合合成方法的开发、新材料的详细结构、电子和光学表征以及原型电子和光电器件的制造。非技术摘要：该项目旨在通过？模块化的？纳米级功能构件的自组装。这种方法可能会产生一类新型的溶液加工半导体，其应用范围从太阳能电池到热电热转换器、发光器件和可印刷电子产品。研究和教育部分的整合将产生广泛的外展和教育活动，包括参与芝加哥科学与工业博物馆纳米科学展览的概念设计和开发。该博物馆每年吸引约 200 万游客，2007 年有近 280,000 名学校团体和青年组织的儿童参观了该博物馆。新展览旨在激励年轻人考虑物理和生物科学方面的教育和职业，其目的是传达现代科学研究的兴奋性、多学科性以及不同科学技术领域之间的协同作用。
