Synthesis and Characterization of Open Framework Materials from Semiconducting Nanoclusters

化学部门的先进材料项目将该奖项授予加州大学河滨分校，以开发新型开放框架硫系材料，以推进新的合成和结构概念，并更好地理解自组装过程和主客体相互作用。凭借该奖项，冯教授将研究有机分子与半导体纳米晶体前体之间的相互作用，以产生更大的团簇，并将这些具有受控表面性质的团簇组织成三维有序框架。这些团簇及其三维组合体的性质将通过改变其无机和有机组分之间的组成和相互作用来控制。更大的纳米晶体的合成可以更好地理解分子和胶体纳米晶体之间的材料转变，从而有助于控制半导体材料合成中的成核和生长过程。在半导体纳米团簇和三维有序框架的合成和表征方面进行研究，以增强对半导体材料纳米晶体合成和组装的理解，这将在磁性和电光器件中具有潜在的应用。该奖项将为研究生和本科生提供固态化学和材料化学方面的教学和研究培训。

The Advanced Materials Program in the Chemistry Division makes this award to University of California Riverside to develop novel open framework chalcogenide materials to advance new synthetic and structural concepts, and to better understand self-assembly processes and host-guest interactions. With this award, Professor Feng will study interactions between organic molecules and the semiconductor nanocrystal precursors to generate larger clusters, and to organize these clusters with controlled surface properties into 3-dimensional ordered frameworks. Properties of these clusters and their 3-D assemblies will be controlled by changing the composition and interactions between their inorganic and organic components. The synthesis of larger nanocrystals may lead to better understanding of material transition between molecules and colloidal nanocrystals, which in turn will help to control nucleation and growth processes in the synthesis of semiconductor materials.Research studies will be carried out in the synthesis and characterization of semiconductor nanoclusters and 3-dimensional ordered frameworks to enhance the understanding of nanocrystal synthesis and assembly of semiconductor materials, which will have potential applications in magnetic and electrooptic devices. Instructional and research training in solid state and materials chemistry will be provided to graduate and undergraduate students with this award.
