Di- and Tetracarboxydiphenylmethanes and Derivatives

Syntheses, structures and properties of a series of organic–inorganic complexes based on methylenediisophthalic acid (H4MDIP)

“…Compound H 4 MDIP (methylenediisophthalic acid) was prepared according to the method reported in the literature. 9 All commercially available chemicals were of reagent grade and used as received without further purification. C and H elemental analyses were made on a Perkin-Elmer 240C elemental analyzer at the analysis center of Nanjing University.…”

Syntheses and solid state structures of hybrid d10 metal–organic frameworks based on methylenediisophthalic acid (H4MDIP)

“…Materials and physical measurement H 4 MDIP was synthesized according to the literature. 9 The bix was synthesized as previously reported. 10 All the other starting materials were of reagent quality and obtained from commercial sources without further purification.…”

Enhancing H2 Uptake by “Close‐Packing” Alignment of Open Copper Sites in Metal–Organic Frameworks

“…A possible design for an “ideal” ligand for the construction of a MOF based on cuboctahedral cages with aligned open metal sites is to keep the two isophthalate moieties to ensure the formation of the cuboctahedral cages but link the two using a bent bridge to prevent the formation of an NbO‐type structure. A ligand designed using such a strategy is 5,5′‐methylene‐di‐isophthalate9 (mdip, Figure 2). Herein we report the synthesis of two Cu–mdip MOFs that are polymorphs of each other: a MOF consisting of cuboctahedra with all the open metal sites aligned, PCN‐12 (PCN represents porous coordination network), and PCN‐12′, in which the open metal sites are out of alignment, as the basis for comparison (Figure 3).…”
