Hybrid Chalcogenides: A New Class of Inorganic-Organic Composite Materials from Solvothermal Media

本计画旨在开发一种新的硫属化合物研究方向，开发有机与无机混合金属硫属化合物。该研究的目标是探索和开发有效的溶剂热路线，以控制合成新的功能杂化材料;表征和修改其结构，化学，电子和物理性质，并了解这些性质之间的相关性;并最终获得有关无机-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式框架结构，和（B）无机-有机网络上的硫族元素（硫，硒和碲），含有无机片段，通过有机间隔通过配位键或共价键互连。有机-无机杂化复合材料可能将无机骨架的上级的电子、磁性、光学性质和热稳定性与有机分子的结构多样性、柔性、高加工性和轻质相结合，以进一步增强和加强其功能。该提案的教育部分将继续发展最近在我们校园建立的材料倡议计划，并让大量研究生和本科生参与材料化学学习和实践研究培训过程。

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.
