研制出了第一个用于金属离子释放的光激活掺杂量子点载体。利用金属-二硫代氨基甲酸盐实现了一种简便的在硫化锌量子点壳中掺杂铜(I)离子的方法，并用X-射线光电子能谱对铜离子进行了表征。量子点的光激发释放了铜离子，这是惠斯根[3+2]环加成反应的有效催化剂。探讨了掺杂程度、催化活性和荧光猝灭之间的关系。
The first photoactivated doped quantum dot vector for metal-ion release has been developed. A facile method for doping copper(I) cations within ZnS quantum dot shells was achieved through the use of metal-dithiocarbamates, with Cu+ ions elucidated by X-ray photoelectron spectroscopy. Photoexcitation of the quantum dots has been shown to release Cu+ ions, which was employed as an effective catalyst for the Huisgen [3+2] cycloaddition reaction. The relationship between the extent of doping, catalytic activity, and the fluorescence quenching was also explored.
