项目摘要

Introduction of mesoporous structures to the sensitive materials of self-powered nanosystems can be expected to be as a new direction in the fabrication of self-powered nanodevices with superior performance and low cost. Based on the experiences in the fabrication of porous materials and the sensing applications, I put great efforts on developing novel porous materials by using new concepts.I reported the first success on the fabrication of mesoporous Au films by using a 'polymeric micelle' approach, and a highly enhanced sensing performance was realized by using the mesoporous Au film. Mesooporous Au films with tunable pore size in the range of 10 to 60 nm were firstly obtained by using the reliable soft-templating approach. When light is incident on the mesoporous Au films, the electrons oscillate collectively, a so-called plasmon, and this greatly enhances the electromagnetic field . According to Babinet's principle in optics, the inverse structure, a mesoporous film, should lead to similar local electromagnetic field enhancements. In this work we found mesospace stimulated optical effects of the mesoporous Au films, which shed new light on the tailoring the optical functionality. From Apr. 2015 to the end of my JSPS period, I have published several papers in top journals, including Nature Commnunications, The Journal of American Chemical Society, and Nano Research. All of the publications are highlighted by both peer researchers and the academic media.

将介孔结构引入到自供电纳米系统的敏感材料中，有望成为制备上级性能、低成本的自供电纳米器件的一个新方向。基于在多孔材料制备和传感应用方面的经验，我致力于利用新的概念开发新型多孔材料，首次报道了利用“聚合物胶束”方法制备介孔Au膜的成功，并利用介孔Au膜实现了传感性能的极大增强。首次采用软模板法制备了孔径在10 ~ 60 nm范围内可调的介孔Au薄膜。当光入射到介孔Au膜上时，电子集体振荡，即所谓的等离子体激元，这极大地增强了电磁场。根据光学中的Babinet原理，逆结构，即中孔膜，应该导致类似的局部电磁场增强。在这项工作中，我们发现了介孔Au薄膜的介孔空间激发的光学效应，这为定制光学功能提供了新的思路。从2015年4月到JSPS结束，我在顶级期刊上发表了多篇论文，包括Nature Commnuncations，The Journal of American Chemical Society和Nano Research。所有的出版物都受到同行研究人员和学术媒体的关注。
