报告题目：Tailoring the Third Dimension in Layered Materials—Direct Synthesis of Layered Intercalation Compounds and Colloidal Single-Layer Nanosheets

报告时间：2014年5月26日（星期一）上午9:00

报告地点：校本部格致楼5004室

Abstract:

Layered materials have been well investigated and have found widespread application. Traditionally, one can only alter the lateral dimension (X and Y directions) of layered compounds. The layer thickness or composition in the Z direction is hard to be finely controlled during the growth of layered compounds. Such a deficit severally limits the possibility during the materials design. Herein we demonstrate that by introducing a layer growth coordinator or inhibitor, one can directly synthesize layered intercalation compounds or single layer nanosheets, respectively. The coordinator or inhibitor helps tailor the interaction between neighboring layers, and in turn help guide or block the interlayer growth. We anticipate the new understanding of how the growth of layered materials can be tailored will be valuable for researchers to design new materials, and to extend the work on 2-D systems to 3-D frameworks.
