“…The band at 1257 cm –1 can be ascribed to C–N vibration . The two peaks centered at 1574 and 1380 cm –1 are assigned to asymmetric (ν as C–O) and symmetric (ν s C–O) vibrations of carboxyl groups, respectively . It can be seen that the FT-IR spectra of the composites (IRMOF-3/GO- x ) are similar to that of IRMOF-3, which could be explained by the fact that the MOF is the principal ingredient of the composites.…”

A new metal-organic framework/graphene oxide composite (IRMOF-3/GO) with high adsorption capacity of copper(II) (maximal adsorption amount = 254.14 mg/g at pH 5.0 and 25 °C) was prepared. Novel and highly efficient nanofiltration (NF) membrane can be facilely fabricated via surface decoration of IRMOF-3/GO onto polydopamine (PDA)-coated polysulfone (PSF) substrate. After decoration of IRMOF-3/GO, membrane surface potential increased from 6.7 to 13.1 mV at pH 5.0 and 25 °C. Due to the adsorption effect of IRMOF-3/GO and the enhancement of membrane surface potential, the prepared NF membrane (the loading amount of IRMOF-3/GO is ca. 13.6 g/m) exhibits a highly efficient rejection of copper(II). The copper(II) rejection reaches up to ∼90%, while maintaining a relatively high flux of ∼31 L/m/h at the pressure of 0.7 MPa and pH 5.0. Moreover, the membrane also presents an outstanding stability throughout the 2000 min NF testing period. Thus, the newly developed NF membrane shows a promising potential for water cleaning. This work provides a worthy reference for designing highly efficient NF membranes modified by metal-organic framework (MOF) relevant materials.

“…Therefore, the biphenyl-4,4 0 -dicarboxylic rigid, linear organic O-donor ligand is employed as organic linkers to construct metalorganic coordination compounds with a variety of coordination modes ( Fig. 1) and different dimensionalities [8][9][10][11][12][13][14][15][16][17][18][19].…”

The lanthanide biphenyl-4,4 0 -dicarboxylates (bpdc) series of the general formulae Ln 2 (bpdc) 3 ÁnH 2 O, where Ln = lanthanides from La(III) to Lu(III); bpdc = C 12 H 5 (COO) 2 2-; n = 4, 5 or 6 have been obtained by the conventional precipitation method. All prepared complexes were characterized by elemental analysis, simultaneous thermal analyses thermogravimetric-differential scanning calorimetry (TG-DSC) and TG-FT-IR, FT-IR, and FTRaman spectroscopy as well as X-ray diffraction patterns measurements. In the whole series of analyzed complexes the bpdc 2-ligand is completely deprotonated. In view of that, four carboxylate oxygen atoms are engaged in the coordination of Ln(III) ions. The synthesized compounds are polycrystalline and insoluble in water. They crystallize in the low symmetry crystal systems, like monoclinic and triclinic. Heating in the air atmosphere resulted in the multi-steps decomposition process, namely endothermic dehydration and strong exothermic decomposition processes. The dehydration process leads to the formation of stable anhydrous Ln 2 bpdc 3 compounds which subsequently decompose to the corresponding lanthanide oxides.

A new 3D silver complex [Ag(mela)(H2O)(NO3)]n (1) (mela = melamine or 2,4,6-triaminotriazine) is synthesized and characterized by single crystal X-ray diffraction, IR, and elemental analysis. The structural characterization shows that the compound crystallizes in space\ud group C c, a = 8.181(2), b = 10.269(3) c = 11.347(3) A ° , b = 105.88(2) A, Z = 4. Out of several structurally characterized transition metal compounds comprising melamine, the titled complex represents a rare example of l3-melamine coordination mode realized through the heterocycle nitrogen donors. The fluorescent property of complex 1 was investigated and the mechanism was validated\ud by means of a density functional theory (DFT) calculation
