随着全球越来越多的处方药和非处方药被消费，越来越多的药物及其代谢物正在进入水中，其净水基础设施并不是为去除它们而设计的。最终，这个问题与越来越多的工业相关废物有机分子(即多环芳烃)一起可能导致大规模的水污染。本文报道了一种由InCl3和四氟对苯二甲酸合成的新型全氟化In衍生金属有机骨架YCM-101。YCM-101能够从水溶液中去除抗生素四环素，推测是通过缺乏电子的MOF接头和四环素的富电子芳香族组分的pi-pi堆积作用完成的。这一假设得到了苯和吡啶参与与YCM-101进行pi-pi堆积的晶体结构的支持。
As more prescription and over-the-counter drugs are consumed worldwide, more and more drugs and their metabolites are entering the water stream with a water purification infrastructure not designed for their removal. Eventually this problem in conjunction with increasing amounts of industrially related waste organic molecules (i.e., PAHs) could lead to largescale water contamination. Herein we report a new perfluorinated In-derived metal-organic framework entitled YCM-101 synthesized from InCl3 and tetrafluoroterephthalic acid. YCM-101 is capable of removing the antibiotic tetracycline from aqueous solution, putatively accomplished via pi-pi stacking interactions of the electron deficient MOF linker and the electron rich aromatic components of tetracycline. This hypothesis was supported by obtained crystal structures of both benzene and pyridine participating in pi-pi stacking with YCM-101.
