在尺寸限制和表面导向作用下，一维金属有机骨架（MOF）纳米结构和超结构的可控生长的新机制已经被发现。通过应用以径迹蚀刻聚碳酸酯（PCTE）膜为模板的界面合成，发现在100 nm的膜孔内形成全等多晶沸石咪唑骨架-8（ZIF-8）固体纳米棒和中空纳米管，而单晶ZIF-8纳米线在30 nm的孔内生长，所有这些都具有高达60的大纵横比，并显示出{100}面平行于孔的长轴排列的优先晶体取向。我们的研究结果提供了一个可推广的方法来控制尺寸，形态和晶格取向的MOF纳米材料。
New mechanisms for the controlled growth of one-dimensional (1D) metal-organic framework (MOF) nano- and superstructures under size-confinement and surface-directing effects have been discovered. Through applying interfacial synthesis templated by track-etched polycarbonate (PCTE) membranes, congruent polycrystalline zeolitic imidazolate framework-8 (ZIF-8) solid nanorods and hollow nanotubes were found to form within 100 nm membrane pores, while single crystalline ZIF-8 nanowires grew inside 30 nm pores, all of which possess large aspect ratios up to 60 and show preferential crystal orientation with the {100} planes aligned parallel to the long axis of the pore. Our findings provide a generalizable method for controlling size, morphology, and lattice orientation of MOF nanomaterials.
