摘要

The study of coordination-driven self-assembled discreteand polymeric metal—organic frameworks (MOFs) is a veryactive interdisciplinary research area.~[1]These metal—organicassemblies have intriguing structures and potential applica-tions as smart optoelectronic, magnetic, and catalytic materi-als. One of the most promising applications for MOFs istheir use as porous materials for molecular adsorption andseparation. Compared with gas storage studies,~[2]investiga-tions into the selective absorption and separation of aromat-ic molecules on MOFs are rare,~[3]especially on MOF singlecrystals. For the previous study, efforts were mainly focusedon the phenomenon of single crystal to single crystal trans-formation (structural dynamism), which is caused by solvent(coordinated or uncoordinated) exchange, temperaturechange, and framework decoration.~[4]However, consciousand systemic studies of guest dynamism, adsorption, andseparation on MOFs that maintain single crystallinity are, tothe best of our knowledge, extremely rare, especially for ar-omatic molecules, although it is known that the separationof C6—05 arenes is very important in industry.
