We report here a new technique for the identification and visualization of functional domains in stratified metal-organic frameworks (MOFs). The technique, namely, gold diffusion enabled domain identification, utilizes the diffusion of Au nanoparticles within MOF cavities to track and selectively stain the more Au-philic domain in an MOF particle thereby allowing direct observation of domains, determination of domain sequences, and, in certain cases, domain boundaries under transmission electron microscopy. This method is an excellent tool for studying MOF materials with complex domain hierarchy.

使用金纳米粒子对分层的有机金属框架中的功能域进行跟踪和可视化。

我们在这里报告了一种新技术，用于识别和可视化分层金属有机框架（MOF）中的功能域。该技术（即金扩散域识别）利用MOF腔内Au纳米颗粒的扩散来跟踪和选择性染色MOF颗粒中更多的Au-philic域，从而可以直接观察域，确定域序列，并在某些情况下，透射电子显微镜下的畴边界。该方法是研究具有复杂域层次结构的MOF材料的绝佳工具。
