“…Consistent with a low porosity structure, nitrogen gas sorption experiments revealed a low BET surface area of 37 m 2 g À 1 for freshly prepared samples of kat-Zn(MeIm) 2 dried in vacuum at room temperature. This is much less than that expected for a microporous material like ZIF-8 (without washing and activation, ZIF-8 prepared from ZnO in aqueous environment exhibits a BET surface area of B1,300 m 2 g À 1 ) 29 . Samples of dia-Zn(MeIm) 2 prepared by mechanochemical collapse of ZIF-8 are non-porous, exhibiting an almost completely flat BET nitrogen sorption curve.…”

“…Crystallization of ZIF-8 from solution has been explored by several groups 26,27 , and a non-porous polymorph of ZIF-8 with a diamondoid (dia) topology was recently reported 28,29 . With the initial aim to simplify the mechanosynthesis of ZIF-8, which requires the presence of weakly acidic salts and an organic liquid (for example, N,Ndimethylformamide), we decided to explore LAG synthesis using only aqueous acetic acid.…”

“…The mobility‐enhancing role during crystallization is in that case similar to that of the stoichiometric liquid in LAG, as the vapor will adsorb on the dry precursor mixture. This vapor‐processing approach for the synthesis of MOF powders has recently been demonstrated for a wide‐range of precursor and vapor combinations under a variety of names, including mineral neogenesis, steam‐assisted conversion, vapor‐assisted aging, and accelerated aging …”

“…The diamondoid ( dia ) phase dia ‐Zn(MeIm) 2 was also observed in the rose stem and for the other portions of the rose, and reed. Previously, the dia phase was discovered to occur for Zn(MeIm) 2 formed in the presence of water, and more recently was demonstrated to form when Zn(MeIm) 2 is synthesized in water around cotton fibers, i.e., cellulose . The presence of the dia phase is therefore expected in some tissue, as cellulose is found in high‐quantities in the cell walls of plant cells.…”
