中文摘要
受到表面等离激元增强的化学与电化学反应诸多特性的启发,本项目拟采用共价键合的方式,将电催化与电化学传感中常用的一类分子型催化剂卟啉组装在金属纳米结构表面,利用等离激元增强分子光谱技术精确解析卟啉分子在金属纳米结构表面的结合构象,为二维平面分子在表界面的定向组装提供指导;另一方面,利用金属纳米结构的局域表面等离激元共振现象激发产生的高能载流子,调控卟啉对小分子电极反应过程的催化活性,并结合实验与理论计算,阐述其内在的调控与电催化机制。在上述研究的基础上,发展基于金属纳米结构表面等离激元增强的卟啉型电化学传感平台,并将其用于谷胱甘肽、多巴胺以及NO等生命相关小分子的高灵敏检测。研究成果对揭示等离激元增强电化学反应过程中的“光-质”作用规律具有重要意义,同时也为高性能分子型传感器与分子器件的设计与发展提供新的思路。
英文摘要
Inspired by the fascinating properties of surface plasmon enhanced chemical and electrochemical reactions, this project plans to covalently assemble metalloporphyrins, one family of the commonly used molecule-type electrocatalysts in both electrocatalysis and electrochemical sensing on the surface of plasmonic metal nanostructures. With the help of plasmon enhanced molecular spectroscopy, the accurate surface-conformation of the porphyrin molecules on nanostructures could be deduced so as to provide guidance toward oriented assembly of 2-dimentional molecules on interfaces. On the other hand, the excited hot carriers generated during the dephasing of localized surface plasmon resonance (LSPR) hold the potential to tuning the catalytic property of the porphyrin, which is the core target of this project. The LSPR tuning effect and the underlying mechanism will be studied in detail, combing multiple-technique based experiments and theoretical calculations. With the ultimate goal as developing a high performance porphyrin-type electrochemical sensing platform for life-related small molecules such as gluthione, dopamine and NO, this project could shed light on the in-depth understanding of “light-matter” interaction during plasmon mediated electrochemical reactions and its final realization could provide new inspirations toward the designing of molecular-type sensors and devices.
