TL;DR: The high CO(2) selectivity over other gases and water stability makes the compound promising candidate for industrial postcombustion gas separation application.
Abstract: A robust and water-stable porous coordination polymer [Cd(NDC)0.5(PCA)]·Gx (1) (H2NDC = 2,6-napthalenedicarboxylic acid, HPCA = 4-pyridinecarboxylic acid, G = guest molecules) with new network topology has been synthesized solvothermally. The framework is 3D porous material and forms a 1D channel along the c-axis, with the channel dimensions ∼9.48 × 7.83 A2. The compound has high selectivity in uptake of CO2 over other gases (H2, O2, Ar, N2, and CH4). The framework is highly stable in presence of water vapor even at 60 °C. The high CO2 selectivity over other gases and water stability makes the compound promising candidate for industrial postcombustion gas separation application.

TL;DR: In this paper, a new water-stable Cd coordination polymer, namely {Cd(INA)(pytpy)(OH)·2H2O}n (1, pytpy=”4′-(4-Pyridinyl)-2,2′:6′,2”-terpyridine, INA =Isonicotinic acid) had been synthesized and structurally characterized by single crystal and powder X-ray diffractions, elemental analysis, FT-IR spectroscopy and TGA.
Abstract: A new water-stable Cd coordination polymer, namely {Cd(INA)(pytpy)(OH)·2H2O}n (1, pytpy = 4′-(4-Pyridinyl)-2,2′:6′,2”-terpyridine, INA = Isonicotinic acid) had been synthesized and structurally characterized by single crystal and powder X-ray diffractions, elemental analysis, FT-IR spectroscopy and TGA. X-ray structural analysis reveals that 1 is constructed by seven-coordinated Cd ions, INA bridges and chelated pytpy ligands, and adopts a 2D supramolecular layered structure sustained through π-π interaction. Luminescence measurements exhibit that 1 can detect 2,4,6-trinitrophenol (TNP) with high sensitivity, selectivity and recyclability in DMF or aqueous medium. The test paper experiment provides a simple and reliable detection method for TNP in practical applications. Moreover, 1 can selectively sense Cu2+ ion in aqueous solutions with a very large quenching coefficient Ksv of 1.3 × 105 M−1, which is comparable to the current maximum. The emission quenching mechanisms of the sensing properties of 1 towards TNP and Cu2+ were preliminarily studied as well. These results demonstrate that 1 can serve as an excellent sensor for TNP and Cu2+ through luminescence quenching process.

TL;DR: A review of polyoxometalates-based coordination polymers with entangled structures can be found in this paper, where different concepts, such as interpenetration, polycatenation, polyrotaxane, poly pseudo-rotaxanes and self-penetrations, are employed to describe the various types of POM-based polymers.

TL;DR: The postsynthetic functionalization of the bridging OH-group between two metal centers of the secondary building units of MIL-53(Al) with 1,1'-ferrocenediyl-dimethylsilane is the proof of principle of a new, selective functionalization method of the "inorganic" part of the porous coordination polymer (PCP).
Abstract: The postsynthetic functionalization of the bridging OH-group between two metal centers of the secondary building units of MIL-53(Al) with 1,1′-ferrocenediyl-dimethylsilane is the proof of principle of a new, selective functionalization method of the “inorganic” part of the porous coordination polymer (PCP). The functionalized material was active in the liquid-phase oxidation of benzene to phenol as a test reaction for redox activity.

TL;DR: The exploration of various experimental parameters led to the formation of four crystalline three-dimensional coordination polymers formulated M(2)(TTF-TC)H(2) (M = K, Rb, Cs), denoted MIL-132(K), MIL-133(isostructural K,Rb), and MIL-134(Cs), which all are thermally stable up to 150-200 degrees C in the air.
Abstract: The reactivity of the redox-active tetracarboxylic acid derived from the tetrathiafulvalene (TTF-TC)H4 with alkaline cations (K, Rb, Cs) is reported. The exploration of various experimental parameters (temperature, pH) led to the formation of four crystalline three-dimensional coordination polymers formulated M2(TTF-TC)H2 (M = K, Rb, Cs), denoted MIL-132(K), MIL-133(isostructural K, Rb), and MIL-134(Cs). Thermogravimetric analysis and thermodiffraction show that all of the solids are thermally stable up to 150−200 °C in the air. In order to exploit the possibility of oxidation of the organic linker in TTF-based compounds, they were employed as positive electrodes in a classical lithium cell. A highly reversible cyclability was achieved at high current density (10 C) with a reasonable performance (∼50 mAh g−1). Finally, combined electro-(sub)hydrothermal synthesis was used to prepare a fifth 3-D coordination polymer formulated K(TTF-TC)H2 (denoted MIL-135(K)), this time not based on the neutral TTF-TC link...
