Structures, photoluminescence and photocatalytic properties of three new metal–organic frameworks based on non-rigid long bridges

Structures and photocatalytic activities of metal-organic frameworks derived from rigid aromatic dicarboxylate acids and flexible imidazole-based linkers

“…In this regard, our recent study has been mainly focused on the synthesis and characterization of new MOFs from accessible raw materials, which show rich structural features and encouraging photocatalytic properties [24,25]. As an extension of our work, herein, 3-nitro-1,2-benzenedicarboxylic acid (3-NO 2 -bdcH 2 ) or pyridine-3,5-dicarboxylic acid (3,5-pdcH 2 ) were chosen as the starting materials together with divalent metal ions, with the aid of flexible bidentate linker 1,1′-(1,4-butanediyl)bis(imidazole) (bbi).…”

“…The photodegradation experiment under visible light irradiation was carried out after the dark adsorption equilibrium achieved according to the previous reported literature [24,25]. In addition, control experiments on the photodegradation of X3B have been carried out.…”

Crystal structure of catena-(acetato-O,O′)(bromo)- [μ-1,1′-(1,4-butanediyl)bis(benzimidazole)-N:N′]cadmium(II), CdBr(C2H3O2)(C18H18N2)

“…In particular, the uses of flexible ligands have attracted remarkable attention because their conformationsare expected to produce many intriguing architectures. Bis(imidazole) ligands are excellent candidates for the construction of extended architectures and supramolecular architectures [7][8][9][10]. 1,1'-(1,4-butanediyl)bis(benzimidazole) (bbim), bearing alonger methylene (-CH 2 -) 4 skeleton, is agood candidate for N-donor linkers.…”

Synthesis, structure, and thermodynamics of a lanthanide coordination compound incorporating 5-nitroisophthalic acid

“…In addition, the presence of electron-withdrawing group nitro and conjugated aromatic rings endows the coordination compounds of 5-H 2 nip with good chemical and thermal stabilities [17]. Although a series of lanthanide coordination compounds of 5-H 2 nip were synthesized, and their fascinating architectures and amazing properties such as optics and magnetics were also reported [18][19][20][21][22][23][24], the detailed thermodynamics of lanthanide-organic frameworks was rarely reported [25,26].…”
