本文报道了一种称为 PLUXter 的系统方法,该方法用于筛选和数据挖掘大量潜在的金属有机骨架化合物,这些化合物已合成,然后用高通量同步辐射 X 射线粉末衍射进行分析。该方法的第一部分利用主成分分析(PCA),它允许按结晶度顺序对材料进行排序,以便可以识别和消除不需要的非晶材料。第二部分允许使用层次聚类分析 (HCA) 观察样本内部和样本之间的结构分组。使用单一连锁距离的分类产生了不令人满意的聚类,但是树状图的结构关系被用来建立和指导组的边界。由此产生的分组特性允许对簇中的代表性结构进行进一步的结构特性研究,从而显着减少时间和资源的使用。
This paper reports on a systematic method--called PLUXter--developed for screening and data mining of large numbers of potential metal-organic framework compounds that have been synthesized then subsequently analyzed with high throughput synchrotron radiation X-ray powder diffraction. The first part of the method utilizes principal components analysis (PCA), which allows materials to be ranked in order of crystallinity so that undesirable amorphous materials may be identified and eliminated. The second part allows structural grouping within and between samples to be observed using hierarchical cluster analysis (HCA). Classification using a single linkage distance produced unsatisfactory clusters however the dendrogram's structural relationships were used to establish and guide the boundaries of groups. The resultant grouping identities allowed further structure-property studies to be undertaken on representative structures from the clusters, significantly reducing time and the use of resources.
