Crosslinking Reactions Applied to the Synthesis and Analysis of Layered Materials

化学系授予圣母大学的这项初学者奖学金支持了玛丽亚·利伯曼教授的研究。本文主要研究了交联反应在层状材料的合成和分析中的应用。最初的研究是用层状金属有机磷酸盐和有机磷酸盐进行的，它们由由有机间隔物分子层连接的金属膦酸层组成。每个有机间隔物都被合成修饰，以包括光化学或电化学激活的交联剂，其功能是以特定方式连接已知数量的相邻分子。将改性的间隔物与适当的金属盐混合，形成层状材料。交联剂的活化形成捕获在层状材料中的分子加合物。交联化化学的研究提供了有关缺陷、结构重排和可能的亚稳材料的信息。这项研究通过发展交联化反应作为一种分析和合成工具，促进了对层状材料的合成和结构的基本理解，这种工具可以应用于层状材料表面和内部的分子单分子层。

This starter grant award of the Chemistry Division to the University of Notre Dame supports the research of Professor Marya Lieberman. The research focuses on crosslinking reactions applied to the synthesis and analysis of layered materials. Initial studies are carried out with layered metal organophosphonates and organophosphates, which consist of layers of metal phosphonate connected by layers of organic spacer molecules. Each organic spacer is synthetically modified to include a photochemically- or electrochemically-activated crosslinker, whose function is to connect a known number of adjacent molecules in a specific manner. The modified spacers are mixed with appropriate metal salts to form layered materials. Activation of the crosslinker forms molecular adducts trapped within the layered material. The study of crosslinking chemistry leads to information on defects, structural rearrangements, and possible metastable materials. This research advances fundamental understanding of the synthesis and structure of layered materials by developing crosslinking reactions as an analytical and a synthetic tool that can be applied to molecular monolayers on surfaces and inside layered materials.
