Two new coordination polymers constructed with the 1,10-phenanthroline derivative 2-(2-chloro- 6-fluorophenyl)-1H-imidazo[4,5-f][1,10]-phenanthroline (L) and different carboxylates, namely, [Cd 2(L) 2(1,3,5- BTC)(Cl)].H 2O (1) and [Co 2(L) 2(1,2,4,5-BTC) (H 2O) 2] (2), have been synthesized under hydrothermal conditions (1,3,5-BTC = 1,3,5-benzenetricarboxylate anion and 1,2,4,5-BTC = 1,2,4,5-benzenetetracarboxylate anion). Crystal data for 1: C 47H 25Cd 2Cl 3F 2N 8O 7, triclinic, space group P1, a = 10:1084(5), b = 14:9285(7), c = 15:2930(4) A° , α = 72:1050(10), β = 86:160(2), γ = 79:6000(10)°, V = 2159:88(16) A° 3, Z = 2. Crystal data for 2: C 24H 13ClCoFN 4O 5, triclinic, space group P1, a = 7:4767(15), b = 10:094(2), c = 14:772(3) A° , α = 91:23(3), β = 100:95(3), γ = 106:57(3)°, V = 1045:8(4) A°3, Z = 2. Their crystal structures have been determined by singlecrystal X-ray diffraction analyses, and the compounds further characterized by physico-chemical and spectroscopic methods. In 1, each 1,3,5-BTC anion connects five Cd(II) atoms to form a double chain. These chains are extended into 2D supramolecular networks through π -π interactions. N-H⋯Cl, N-H⋯O and O-H⋯N hydrogen bonding interactions further stabilize the network of 1. In 2, each 1,2,4,5-BTC anion bridges four Co(II) atoms to yield a chain. p-p interactions among adjacent chains result in a 2D supramolecular architecture. © 2012 Verlag der Zeitschrift für Naturforschung.

A series of phenylene-based conjugated microporous polymers (CMPs) of the A6 + Mx (x = 2, 3, 4, 6) type were synthesized. By tuning the monomer length and geometry, the BET surface area of CMPs can be tuned from 571 to 1115 m2 g-1. Amongst the synthesized CMPs, A6CMP-1 exhibits the highest CO2 adsorption capacity of 1218 mg g-1 at 318 K and 60 bar pressure. In addition, A6CMP-4 shows a high selectivity ratio of 47 for CO2/N2. © 2016 Royal Society of Chemistry.

One transition metal-organic framework [Zn(TBTC)(2,6-pydc)]n (1), has been assembled from a mixed ligand 4,5,9,14-tetraaza-benzo[b] triphenylene-11-carboxylic acid (HTBTC) with the help of pyridine-2,6- dicarboxylic acid (2,6-pydc)ligand. X-ray single crystal diffraction analysis reveals that compound 1 crystallizes in the space group of P21/c and displays a one-dimensional (1D) zigzag infinite chain, which is extended via the π-π stacking interactions between pyrazine rings and benzene rings to form 2D supramolecular layers. Compound 1 shows an excellent photocatalytic activity through degradation of methyl blue (MB), methyl violet (MV), rhodamine B (RhB) and orange G (OG). The rate of photodegradation for MV can reach 90% under Xe lamp irradiation after 4.5 h. In addition, catalytic mechanism was also discussed. © 2014 Elsevier B.V.

In the compound [Pb2(L)2(1,4-bdc)2] n (1), each Pb(II) atom is seven-coordinated by two nitrogen atoms from one L ligand, and five carboxylate oxygen atoms from three different 1,4-bdc ligands in a distorted monocapped triangular prismatic coordination geometry (1,4-bdc = 1,4-benzenedicarboxylate and L = dipyrido[7,6-a:6′, 7′-c]-3-chloropyrido[2,3-b]quinoxaline). The Pb(II) atoms are connected together by the 1,4-bdc ligands to form a 2D network with large windows. The dangling L ligands of each layer are threaded into the voids of the two adjacent layers above and below, thus every window of each layer is threaded by only two dangling ligands that come from opposite directions. Finally, this unique simultaneous threading fashion of adjacent polymeric motifs gives the novel 2D → 3D polythreading array. In addition, the strong π-π interactions between the L ligands and the 1,4-bdc ligands of neighboring layers make great contribution to the structural stabilization of 1. © 2011 Elsevier B.V.

In this article, four new lead(II) coordination polymers based on a N,O-donor ligand 2′-(1 H-1,3,7,8-tetraaza-cyclopenta[l]phenanthren-2-yl) biphenyl-2-carboxylic acid (HL) have been hydrothermally synthesized, namely, [PbL2]·2H2O (1), [PbL2]·2H 2O·CH3CH2OH (2), [Pb5L 2(m-BDC)4]·3H2O (3) and [Pb 2L2(p-BDC)] (4), where m-BDC = 1,3-benzenedicarboxylate and p-BDC = 1,4-benzenedicarboxylate. Compound 1 shows a 2D bilayer structure, which is further extended into a 3D supramolecular structure through π-π stacking interactions. Compound 2 shows a 3D supramolecular structure based on a zero-dimensional molecule by π-π stacking interactions of neighboring molecules. Compound 3 shows a 2D layer structure. Compound 4 displays a 1D chain-like structure, which is then stacked by π-π interactions to result in a 2D supramolecular structure. Solid-state luminescent spectra of four lead(II) complexes indicate intense fluorescent emissions. © 2012 Elsevier B.V. All rights reserved.

In compound 1, the L ligand coordinates with two Cu(II) atoms to form a [Cu2L]2+ unit. In compound 2, two ox anions chelate to one Cu(II) atom to form a [Cu(ox)2]2- unit. The (H6L)4+ acts as a counter ion. The whole structures of 1 and 2 feature three-dimensional (3D) supramolecular architectures connected by weak Cuâ̄O and hydrogen-bonding interactions, respectively. In compounds 3-5, the [M2L]2+ cations are bridged by nds, m-bdc and ox anions to form chains, respectively. The chains of 3 and 4 are further linked by hydrogen-bonding interactions into 2D and 3D supramolecular architectures, respectively. In compound 6, the macrocyclic L anion coordinates to two Cd(II) atoms to form a [Cd 2L]2+ cation. The final structure of 6 exhibits a 3D supramolecular architecture linked by hydrogen bonds. In compound 7, Cd(II) atoms are linked by L anions to form two types of [Cd2L]2+ cations. One type of [Cd2L]2+ cations are bridged by btec anions to generate a polymeric anion chain, whereas the other [Cd 2L]2+ cations are free. Further, the polymeric anion chains and the [Cd2L]2+ cations are linked by hydrogen bonds to generate a 2D supramolecular layer. In compound 8, btec anion bridges the [Ni2L]2+ cations to yield a 2D layer. Thermogravimetric analyses (TGA) for the compounds 1-8 have been investigated. In addition, the magnetic property for 1 and the luminescent properties for compounds 3-7 have also been studied. © 2013 Elsevier Ltd. All rights reserved.
