This project aims to develop a new direction in chalcogenide research concerned with the exploitation of hybrid metal chalcogenides composed of both organic and inorganic components. The goal of the research is to explore and develop effective solvothermal routes towards controlled synthesis of new, functional hybridized materials; to characterize and modify their structural, chemical, electronic and physical properties and to understand the correlation between these properties; and finally to acquire fundamental knowledge regarding the chemistry of inorganic-organic composite materials. The focus will be on (a) open-framework structures involving organic templates, and (b) inorganic-organic networks built upon chalcogen(Sulfur, Selenium, and Tellurium)-containing inorganic fragments that are interconnected by organic spacers via coordinate or covalent bonds. %%%Organic-inorganic hybrid composite materials are likely to combine superior electronic, magnetic, optical properties, and thermal stability of inorganic frameworks with the structural diversity, flexibility, high processability, and light-weight of organic molecules to further enhance and strengthen their functionality. The educational component of this proposal will be to continue to develop the Materials Initiative Program recently established at our campus and to involve a large number of both graduate and undergraduate students in the materials chemistry learning and in hands-on research training processes.

本项目旨在发展硫化物研究的新方向，涉及开发由有机和无机组分组成的杂化金属硫化物。这项研究的目标是探索和开发有效的溶剂热途径来控制合成新型的功能杂化材料；表征和修改它们的结构、化学、电子和物理性质，并了解这些性质之间的相关性；最后获得关于无机-有机复合材料化学的基础知识。重点将放在(A)涉及有机模板的开放框架结构，以及(B)建立在含有硫族(硫、硒和碲)的无机片段上的无机-有机网络，这些无机片段通过有机间隔体通过配位或共价键相互连接。有机-无机杂化复合材料很可能将无机骨架优异的电学、磁性、光学和热稳定性与有机分子的结构多样性、柔韧性、高加工性和轻量化结合在一起，进一步增强和增强其功能。这项建议的教育部分将是继续发展最近在我们校园设立的材料倡议计划，并让大量研究生和本科生参与材料化学学习和动手研究培训过程。
