“…16 The N 2 surface area is also similar to those reported by Zhou and co-workers for the PCN-17 series (Er, 606; Dy, 738; Yb, 820 m 2 g −1 ). 21,22 Hong and co-workers recently reported a porous lanthanide-based coordination polymer, using the tctpo 3− ligand with early Ln(III) ions, (Ln = Nd, Sm, Eu, Gd). 12 These polymers showed lower CO 2 BET surface areas and total pore volumes of 793-1079 m 2 g −1 and 0.344-0.487 cm 3 g −1 respectively.…”

The structure, stability, gas sorption properties and luminescence behaviour of a new lanthanidephosphine oxide coordination material are reported. The polymer PCM-15 is based on Tb(III) and tris( p-carboxylated) triphenylphosphine oxide and has a 5,5-connected net topology. It exhibits an infinite three-dimensional structure that incorporates an open, two-dimensional pore structure. The material is thermally robust and remains crystalline under high vacuum at 150°C. When desolvated, the solid has a CO 2 BET surface area of 1187 m 2 g −1 and shows the highest reported uptake of both O 2 and H 2 at 77 K and 1 bar for a lanthanide-based coordination polymer. Isolated Tb(III) centres in the as-synthesized polymer exhibit moderate photoluminescence. However, upon removal of coordinated OH 2 ligands, the luminescence intensity was found to approximately double; this process was reversible. Thus, the Tb(III) centre was used as a probe to detect directly the desolvation and resolvation of the polymer.

“…Besides the N-containing ligands, rigid multi-carboxylate ligands are intriguing components owing to their easily predictable and stable resulting framework [9][10][11][12][13][14][15][16][17]. Among all of the multi-carboxylate ligands, many C 3 -symmetric tricarboxylate ligands have been extensively investigated to construct CPs with interesting architectures and properties, including H 3 TATB and H 3 BTB (TATB denotes 4,4 ,4 -s-triazine-2,4,6-triyltribenzoate and BTB denotes benzene-1,3,5-tribenzoate) [18][19][20].…”

Abstract:A novel Pr complex, constructed from a rigid three-connected H 3 TMTA and praseodymium(III) ion, has been synthesized in a mixed solvent system and characterized by X-ray single crystal diffraction, infrared spectroscopy, a thermogravimetric analysis, an element analysis, and powder X-ray diffraction, which reveals that complex 1 crystallizes in a three-dimensional porous framework. Moreover, the thermal stabilities and the fluorescent and gas adsorption and separation properties of complex 1 were investigated systematically.

The structure of the complexes [UO 2 (TPA)(Azole)(H 2 O)].xH 2 O, TPA = 1,4-benzenedicarboxylic acid and azoles = 2-aminobenzothiazole, 2-aminothiazole, 2-amino-4-methylthiazole and 2-mercaptobenzothiazole has been prepared and characterized. The structure of the complexes has been assigned based on elemental analysis, IR, electronic spectral studies, magnetic measurement, molar conductance, Scanning electron microscope (S.E.M), X-ray powder diffraction techniques investigations and thermogravimetric analysis complete the characterization of the compound. Thermogravimetry(TG), derivative thermogravimetry (DTG) and differential thermal analysis (DTA) have been used to study the thermal decomposition of the complexes. The kinetic parameters have been calculated making use of the Coats-Redfern and Horowitz-Metzger. The scanning electron microscope SEM photographs and particle size calculations from the powder XRD data indicate the average size of the prepared UO 2 (II) (28-56 nm) supramolecular coordination polymers in the nanoscale range. The biological screening of the compounds was also tested.
