Sulfation of metal–organic frameworks: Opportunities for acid catalysis and proton conductivity

The oxamate route, a versatile post-functionalization for metal incorporation in MIL-101(Cr): Catalytic applications of Cu, Pd, and Au

“…In order to address these limitations, different post-synthetic modifications (PSM) have been developed to allow the preparation of highly functional MOF structures regardless of the synthesis method [35][36][37][38].…”

New Group 13 MIL‐53 Derivates based on 2,5‐Thiophenedicarboxylic Acid

“…This so-called isoreticular chemistry [4] enables a broad field of potential applications for these compounds, such as gas storage and separation, catalysis and drug delivery. [5][6][7] For the synthesis of isoreticular compounds, high-throughput (HT) methods have proven to be an important and efficient tool, since the replacement of one component in a reaction mixture often necessitates alteration of the reaction conditions. [8][9][10] The focus of our work is on MOFs based on trivalent cations, in particular on aluminum, since these materials are known for their excellent thermal and chemical stabilities.…”

Protonic Conductivity of Nanocrystalline Zeolitic Imidazolate Framework 8

“…The post-functionalizationof MOFs MIL-101(Cr) and MIL-101(Al) with sulfonic acid groups (similarly to Nafion ® ) was also attempted, but the obtained conductivity drops by about 5 orders of magnitude above 60 °C due to a decrease of the relative humidity (RH). [11]Dybtsev and co-workersincorporated triflic acid into the same MIL-101(Cr) framework achieving similar conductivities that appear to be less dependent on RH, but that also decrease above 60 °C. [12]The conductivity of structures containing carboxylic groups and Cr/Mn metallic centres is in the range 10 -2 -10 -3 Scm -1 at 25°C and 98% RH, but these figures drop orders of magnitude for just a slight decrease of RH, or above 50°C.…”
