The high catalytic activity of metal-organic frameworks (MOFs) can be realized by increasing their effective active sites, which prompts us to perform the functionalization on selected linkers by introducing a strong Lewis basic group of fluorine. Herein, the exquisite combination of paddle-wheel [Cu(CO)(HO)] clusters and meticulously designed fluorine-funtionalized tetratopic 2',3'-difluoro-[-terphenyl]-3,3″,5,5″-tetracarboxylic acid (F-Hptta) engenders one peculiar nanocaged {Cu}-organic framework of {[Cu(F-ptta)(HO)]·5DMF·2HO} (), which features two types of nanocaged voids (9.8 Å × 17.

The intrinsic advantages of metal-organic frameworks (MOFs), including extraordinarily high porosities, tailorable architectures, and diverse functional sites, make the MOFs platforms for multifunctional materials. In this study, we synthesized two kinds of isostructural NbO-type Zn-based MOFs, where two structurally similar tetracarboxylate ligands, 5,5'-(pyrazine-2,5-diyl)diisophthalic acid (HPZDDI) and 5,5'-(pyridine-2,5-diyl)diisophthalic acid (HPDDI), with pyridine or pyrazine moieties, were employed as the organic linkers. By embedding the red-emitting cationic units of pyridinium hemicyanine dye 4-[p-(dimethylamino)styryl]-1-methylpyridinium (DSM) and trivalent europium ion (Eu), two types of composites, DSM@ZnPZDDI and DSM@ZJU-56 and Eu@ZnPZDDI and Eu@ZJU-56, were harvested and evaluated for use as potential ratiometric temperature probes.

Visible-light driven photoreactions using metal-organic frameworks (MOFs) as catalysts are promising with regard to their environmental friendly features such as the use of renewable and sustainable energy of visible light and potential catalyst recyclability. To develop potential heterogeneous photocatalysts, a family of three copper(II) coordination polymers bearing different Cu-O assemblies have been synthesized with the ligand 4,4'-disulfo-[1,1'-biphenyl]-2,2'-dicarboxylate acid (HDSDC), namely, {[Cu(DSDC)(OH)(HO)]·HO} (), {[Cu(DSDC)(4,4'-bpy)(OH)]·2HO} (), and {Cu(DSDC)(phen)(HO)} () (4,4'-bpy = 4,4'-bipyridine and phen = 1,10-phenanthroline). Complex represents a metal-organic framework featuring a NbO type topology constructed from the infinite linkage of heptanuclear [Cu(μ-OH)(HO)] clusters by deprotonated DSDC ligands, comprising one-dimensional hexagonal channels of a diameter around 11 Å that are filled with water molecules.
