Abstract

Amorphous zeolitic imidazolate frameworks (ZIFs) offer promising applications as novel functional materials. Herein, amorphization of ZIF-L through scanning-electron-beam exposure is demonstrated, based on amorphization of individual ZIF-L crystals. The amorphized ZIF product has drastically increased stability against dissolution in water. An electron dose that allows for complete preservation of amorphous particles after immersion in water is established, resulting in new shapes of amorphous ZIF-L with spatial control at the sub-micrometer length scale. Changed water stability as a consequence of scanning-electron-beam exposure is demonstrated for three additional metal–organic frameworks (ZIF-8, Zn(BeIm)OAc, MIL-101), highlighting the potential use of an electron beam for top-down MOF patterning. Lastly, recrystallization of ZIF-L in the presence of linker is studied and shows distinct differences for crystalline and amorphized material.
