A new C2-symmetric TADDOL-based ligand H4L was designed and synthesized from readily available tartaric acid and was used to construct a novel TADDOL-based chiral metal-organic framework {[Co2L(DMA)(H2O)5]·2DMA}n 1 (DMA = N,N′-dimethylacetamide). It was characterized by single-crystal and powder X-ray diffraction, Fourier-transform infrared spectra (FTIR), solid-state circular dichroism (CD) and thermal gravimetric analysis (TGA). 1 crystallizes in the chiral orthorhombic space group P212121 with a = 9.7060(8), b = 15.5661(1), c = 44.564(3) Å, V = 6732.9(9) Å3, Z = 4, Mr = 1394.08, Dc = 1.375 g/cm3, F(000) = 2888, GOOF = 1.032, the final R = 0.0607 and wR = 0.1582 for 21374 observed reflections with I > 2σ(I). Each Co2 cluster in 1 is linked by three ligands and each ligand is coordinated to three Co2 clusters with one free carboxylate group, thus generating a 2D network. These 2D networks are further extended into a 3D supramolecule framework by the hydrogen bonding interactions (O-H⋯O) in an A-B-A-B stacking mode. Additionally, the photoluminescence of 1 and H4L were also investigated.

Dipyridyl-functionalized salan ligand (H2L) was synthesized to construct a mononuclear Cu(salan) complex, [CuL(CH3CN)2(H2O)6] (1), through diffusion method. 1 was characterized by IR, microanalysis, TGA and single-crystal X-ray crystallography. It crystallizes in orthorhombic space group P21212 with a=17.6640(16), b=18.6750(16), c=16.0625(14) , V=5298.6(8) 3, Z=4, Mr=994.70, Dc=1.247 g/cm3, F(000)=2116, μ=0.469 mm-1, GOOF=1.073, the final R=0.0499 and wR=0.1395 for 11816 observed reflections with I > 2(I). In the title compound, the basic building unit consists of two mononuclear Cu(salan) which orient in opposite directions and are locked together via weak intermolecular C-Hφ interactions. The adjacent building units are further directed into a 2D supramolecular network structure via H bonds, between which reside the guest acetonitrile and water molecules. In addition, the presence of exposed NH-functionalities and coordination unsaturated Cu centers in 1 provide a great chance to recognize tartaric acids through CD titration in solution.

A new ligand 2,5-di(pyridin-4-yl)benzaldehyde (L) was synthesized by the reaction of pyridin-4-yl-boronic acid with 2,5-dibromobenzaldehyde. Two novel CdII coordination polymers, [CdL(BDC)]·DMF (1) and [CdL(BPDC)] ·4H2O (2) (BDC = 1,4-benzenedicarboxylate, BPDC = 4,4- biphenyldicarboxylate), have been constructed based on the mixed ligands of L and dicaboxylic acid via solvothermal synthesis, and characterized by IR, microanalysis, TGA, single and power X-ray diffraction, and their fluorescence properties were also investigated. 1 crystallizes in orthorhombic space group Pcca with a = 15.8236(3), b = 16.0038(3), c = 20.2207(3) Å, V = 5120.64(16) Å3, Z = 8, Mr = 633.83, Dc = 1.644 g/cm 3, F(000) = 2528, GOOF = 1.130, the final R = 0.0568 and wR = 0.1513 for 4108 observed reflections with I > 2ν(I). 2 crystallizes in orthorhombic space group Pbcn with a = 29.1148(1), b = 16.0120(6), c = 16.7097(7) Å, V = 7789.8(5) Å3, Z = 8, Mr = 675.88, Dc = 1.153 g/cm3, F(000) = 2712, GOOF = 1.088, the final R = 0.0670 and wR = 0.1805 for 6047 observed reflections with I > 2ν(I). The dinuclear Cd2(CO2)4 unit is linked by BDC in 1 to form a 2D sheet that is further pillared by L to create a 3D metal-organic framework, which possesses a parallelogram channel with diagonal distances of ̃13.3 × 17.6 Å along the b direction. 2 is structurally similar to 1, but has larger diagonal distances of ~14.0 × 26.7 Å due to the elongated auxiliary ligand BPDC compared with the BDC ligand in 1. They are both thermally stable and exhibit strong photoluminescence in the visible region. Copyright © 2008 Chinese Journal of Structural Chemistry.

Dicarboxyl-functionalized salen ligand 1,2-phenylendiamine-N,N′- bis(3-tert-butyl-5-(carboxyl)-salicylide-ene (H4L) was synthesized in good yield from 3-tert-butyl-5-formyl-4-hydroxybenzoic acid and used to construct a 2D zinc complex, [(ZnL)Zn3/2(BDC)1/2(DMSO) 2] 3DMSO (1, BDC = 1,4-benzenedicarboxylate), under mild reaction conditions. 1 was characterized by IR, microanalysis, TGA and single-crystal X-ray crystallography. It crystallizes in triclinic space group P1̄ with a = 11.3860(4), b = 13.2636(5), c = 17.5503(7) Å, α = 92.2240(10), β = 94.5070(10), γ = 96.0580(10)°, V = 2624.52(17) Å3, Z = 2, Mr = 1143.62, Dc = 1.448 g/cm3, F(000) = 1186, μ = 1.395 mm-1, GOOF = 0.993, the final R = 0.0380 and wR = 0.1280 for 21752 observed reflections with I > 2σ(I). The 2D coordination polymer 1 is further assembled into a 3D supramolecular network structure via π π interactions between the aromatic rings of the ligands in adjacent layers. Thermal gravimetric analysis demonstrates that 1 is a thermally robust structure with network decomposition temperatures of 420 °C and it also exhibits strong photoluminescence in the visible region.

A chiral 3D metal-organic framework [CdL]·DMSO·H2O (1) was constructed by an N-methyl substituted salan ligand (H2L), and characterized by elemental analyses, IR, TGA, powder XRD and single-crystal X-ray crystallography. 1 crystallizes in the chiral hexagonal space group P6522 with a = b = 12.2175(3), c = 51.450(3) Å, V = 6650.9(4) Å3, Z = 6, Mr = 883.45, Dc = 1.323 g·cm-3, F(000) = 2760, λ(CuKα) = 1.54178 Å, μ = 4.771 mm -1, GOOF = 1.041, R = 0.0313 for 3901 observed reflections with I > 2σ(I) and wR = 0.0773. 1 consists of three identical sets of independent 3D frameworks interpenetrated with each other. In each set of such 3D frameworks, one half of the monomer (CdL)1/2 as the building unit forms double antiparrel helical chains which are further bridged together by other (CdL)1/2 units from adjacent helical chains. All CdL units in 1 adopt Δ geometry. DMSO and water guest molecules are found in the gap of the interpenetrated frameworks.

Objectives: To investigate the conversion of lutein, a carotenoid, to aroma compounds by Pantoea dispersa Y08, a lutein-degrading bacterium isolated from marigold flower residue. Bioconversion conditions, including substrate concentration, applied co-solvent and reaction time, were optimized. Results: A maximum biodegradation yield of 80 % for lutein at 10 g/l was achieved. The intermediate, 3-hydroxy-β-ionone, and final β-ionone products were revealed by GC–MS. A bioconversion pathway of lutein is proposed to involve cleavage at the 9–10 double bond position, followed by de-hydroxylation at the 3-hydroxy position. Conclusions: This is the first report of the ability of a bacterium, P. dispersa, to sequentially convert lutein to 3-hydroxy-β-ionone and then β-ionone. © 2015, Springer Science+Business Media Dordrecht.
