Isoreticular Expansion of Metal–Organic Frameworks with Triangular and Square Building Units and the Lowest Calculated Density for Porous Crystals
摘要:
The concept and occurrence of isoreticular (same topology) series of metal organic frameworks (MOFs) is reviewed. We describe the preparation, characterization, and crystal structures of three new MOFs that are isoreticular expansions of known materials with the tbo (Cu-3(4,4',4 ''-(benzene-1,3,5-triyl-tris(benzene-4,1-diy1))tribenzoate)(2), MO F-399) and pto topologies (Cu-3(4,4',4 ''-(benzene-1,3,5-triyltribenzoate)(2), MOF-143; Cu-3(4,4',4 ''-(triazine-2,4,6-triyl-tris-(benzene-4,1-diyl))tribenzoate)(2), MOF-388). One of these materials (MOF-399) has a unit cell volume 17 times larger than that of the first reported material isoreticular to it, and has the highest porosity (94%) and lowest density (0.126 g cm(-3)) of any MOFs reported to date.
Metal‐organicframeworks (MOFs) are a class of porous coordination polymer. Recently, some studies have been focused on the detection of various analytes using luminescent MOFs. In this study, an MOF, Eu@1, is synthesized using ([Zn3(TAPB)2(CH3OH)2]) (1) as a precursor to encapsulate Eu3+. It has large pores and excellent luminescent properties, and the quantum yield is up to 30.2%, which can be used

cluster have been prepared as ZrL1 (without any branch), ZrL2 (with −F), and ZrL3 (with −SCH3). The electrocatalytic hydrogen evolution reaction (HER) by their pristine and transition metal-loaded (TM-loaded) forms was studied. It was found that the loading of TM ions could enhance the electrocatalytic power of these TM-loaded MOFs in HER, as reflected by their lower overpotentials and smaller Tafel
