摘要
量子点作为新型荧光材料广泛应用于分子识别研究,其表面功能化修饰能有效改善它在分子识别中的选择性和灵敏度。本文以功能化基团与量子点的连接方式分类,分为:以硫原子为连接基的功能化量子点(包括简单巯基化合物修饰的量子点、以简单巯基化合物为前驱体修饰的量子点、其他含巯基化合物修饰的量子点以及含CS2化合物修饰的量子点)、以氧原子为连接基的功能化量子点和以氮原子为连接基的功能化量子点。评述了近5年来上述功能化量子点在无机离子和小分子识别研究中的应用。
Quantum dots（QDs） attract extensive research interest as optical labels for sensing events owing to their outstanding photophysical features.Molecule and ion recognition has been combined very recently with the unique optical properties of QDs to begin building a new generation of QD-based sensors,that is,functional modification of QDs.Surface functional modification for QDs can improve their water solubility and recognizing selectivity.This review,which follows the classification of linked atom between QDs and functional ligands such as QDs linked with sulfur atom（including modification QDs with simple mercapto compound,modification QDs using simple mercapto compound as precursor,modification QDs with other mercapto compound and modification QDs using carbon disulfide as linker）,QDs linked with oxygen atom and QDs linked with nitrogen atom,summarizes the research for recognizing of inorganic ion and small molecule based on above functional modification of QDs from 2005 to update.
