Self-assembly of metal–organic coordination polymers occurs because of enthalpically favorable interactions. In the case of the bulky 4,4′-(anthracene-9,10-diyl)dibenzoic acid ligand (abdH2), we demonstrate that the presence of numerous π–π and C—H...π interactions outweigh the formation of saturated coordination complexes with zinc, leading to the formation of a dimethylformamide (DMF) solvate, namely 4,4′-(anthracene-9,10-diyl)dibenzoic acid dimethylformamide disolvate, C28H18O4·2C3H7NO or [(abdH2)(DMF)2], at low concentrations of zinc. Meanwhile, at higher zinc concentrations, the abdH2 ligand gives rise to the nonporous one-dimensional coordination polymer catena-poly[[bis(dimethylformamide-κO)zinc(II)]-μ-4,4′-(anthracene-9,10-diyl)dibenzoato-κ2 O:O′], [Zn(C28H16O4)(C3H7NO)2] n or [Zn(abd)(DMF)2] n , when assembled in dimethylformamide, while a related compound is observed when N,N-dimethylacetamide (DMA) is used as the solvent, namely catena-poly[[[bis(N,N-dimethylacetamide-κO)zinc(II)]-μ-4,4′-(anthracene-9,10-diyl)dibenzoato-κ2 O:O′] N,N-dimethylacetamide monosolvate], {[Zn(C28H16O4)(C4H9NO)2]·C4H9NO} n or {[Zn(abd)(DMA)2]·DMA} n . Attempts to use other amide-based solvents did not give rise to any other assembled structures.

One of the most interesting phenomena in coordination polymers (CPs) is the co-existence of different interlaced motifs. However, CPs having two different interlaced motifs at the same time are still rare. Colourless block-shaped crystals of the two-dimensional polymer poly[[aqua(μ2-naphthalene-2,6-dicarboxylato){μ2-4,4′-[oxybis(4,1-phenylene)]dipyridine}cadmium(II)] monohydrate], {[Cd(C12H6O4)(C22H16N2O)(H2O)]·H2O} n , (I), was synthesized under hydrothermal conditions by the self-assembly of 4,4′-[oxybis(4,1-phenylene)]dipyridine (OPY) with CdII in the presence of naphthalene-2,6-dicarboxylic acid (H2ndc). Each CdII ion is six-coordinated by two N atoms from the pyridine rings of two OPY ligands and by four O atoms, three of which are from two ndc2− ligands and one of which is from a water molecule. In (I), every two identical two-dimensional (2D) 63 layers are interpenetrated in a parallel fashion, resulting in an interesting 2D→2D framework with both polyrotaxane and polycatenane characteristics. The extension of these sheets into a three-dimensional supramolecular net is via O—H...O hydrogen bonds. The solid-state photoluminescence properties of (I) are also discussed.

The major protein of the blue-green algae is the biliprotein, C-phycocyanin (Amax = 620 nm), which is presumed to exist in the cell in the form of distinct aggregates called phycobilisomes. The self-assembly of C-phycocyanin from monomer to hexamer has been extensively studied, but the proposed next step in the assembly of a phycobilisome, the formation of 19s subunits, is completely unknown. We have used electron microscopy and analytical ultracentrifugation in combination with a method for rapid and gentle extraction of phycocyanin to study its subunit structure and assembly.To establish the existence of phycobilisomes, cells of P. boryanum in the log phase of growth, growing at a light intensity of 200 foot candles, were fixed in 2% glutaraldehyde in 0.1M cacodylate buffer, pH 7.0, for 3 hours at 4°C. The cells were post-fixed in 1% OsO4 in the same buffer overnight. Material was stained for 1 hour in uranyl acetate (1%), dehydrated and embedded in araldite and examined in thin sections.
