近年来,金属-有机超分子笼在超分子化学中扮演着越来越重要的角色。在主客体化学中,金属-有机超分子笼因其特定空腔可以包裹各种客体分子,并在催化、吸附、分离等领域展现出巨大的应用前景。然而,由于金属-有机超分子笼的结构复杂,性质较为不稳定,笼子本身和它的主客体作用很难用质谱技术表征。为了解决金属-有机超分子笼及其主客体作用在质谱测试和分析中的难点,本文利用电喷雾飞行时间质谱,选择Ru-Pd金属-有机超分子笼(MOC-16)为主体,加入客体芘进行主客体作用的分析,并对测试的条件进行讨论。研究结果表明,电喷雾飞行时间质谱可以有效地实现对MOC-16及其主客体作用的分析和表征。
In recent years, metal-organic cages have played an increasingly important role in supramolecular chemistry. Metal-organic cages have specific cavities that can encapsulate various guest molecules, and thus show great potentials in such fields as catalysis, adsorption and separation. However, due to their complex structure and unstable nature of metal-organic supramolecular cages, the cage itself and its host-guest properties are difficult to be characterized by mass spectrometry. In order to solve the difficulties of the metal-organic supramolecular cage and its host-guest behavior in analyzing mass spectrometry experiment, this paper analyzes the addition of pyrene to MOC-16 by electrospray time-of-flight mass spectrometry. The research results show that mass spectrometry can effectively analyze the effects of MOC-16 and its host-guest properties.
