Controlled synthesis of hydrogen-bonded organic frameworks (HOFs) remains challenging, because the self-assembly of ligands is not only directed by weak hydrogen bonds, but also affected by other competing van der...

The central copper(II) atom of the title salt, {[Cu(CF3SO3)(CH3CN)2(C12H12N2O2)](CF3SO3)} n or [[Cu(CH3CN)2(diOMe-bpy)(CF3SO3)](CF3SO3)] n where diOMe-bpy is 4,4′-dimethoxy-2,2′-bipyridine, C12H12N2O2, is sixfold coordinated by the N atoms of the chelating bipyridine ligand, the N atoms of two acetonitrile molecules, and two trifluoromethanesulfonate O atoms in a tetragonally distorted octahedral shape. The formation of polymeric chains [Cu(CH3CN)2(diOMe-bpy)(CF3SO3)]+ n leaves voids for the non-coordinating trifluoromethanesulfonate anions that interact with the complex through weak hydrogen bonds. The presence of weakly coordinating ligands like acetonitrile and trifluoromethanesulfonate makes the title compound a convenient starting material for the synthesis of novel metal–organic frameworks.

The self-assembly structures of 2,2[Formula: see text]:6[Formula: see text],2[Formula: see text]-terpyridine-4[Formula: see text]-carboxylic acid (C[Formula: see text]H[Formula: see text]N3O2; [Formula: see text]) molecules and 3,5-diphenylbenzoic acid (C[Formula: see text]H[Formula: see text]O2; [Formula: see text]) molecules on Ag(110) surface have been investigated by scanning tunneling microscopy (STM) and Density Functional Theory (DFT) calculation. The [Formula: see text] molecules form two different well-organized structures due to the [Formula: see text]–[Formula: see text] stacking and dipole–dipole interactions. When three C atoms of [Formula: see text] molecules are replaced by three N atoms to form [Formula: see text] molecules, the main driving force to form ordered assembly structures of [Formula: see text] molecule is changed to metal–organic coordination bond and hydrogen bond. The dramatic changes of main driving force between [Formula: see text]/Ag(110) and [Formula: see text]/Ag(110) system demonstrate that the N atoms are apt to form metal–organic coordination bond and hydrogen bond but dipole–dipole interactions and [Formula: see text]–[Formula: see text] stacking are relative to C atoms. These findings further reveal that the optimization design of organic molecules could vary the main driving force and then lead to the change of the molecular self-assembly structures.

The self-assembly of the bifunctional 4,4'-bipyridine (bipy) with bowl-shaped C-iso-butylresorcinarene (1) under two different conditions was investigated. The 0D carcerand-like capsule complex 1 · 2(bipy) · 0.5EtOH · 4H2O (3) with four stacked bipys was formed in 95% ethanol solution. The 2D wave-like layered sheet complex 1 · 2(bipy) ·CH3CN · 2H2O (4) constructed by bipy bridging 1D wave-like ribbons with hydrogen-bonded planar hexagonal rings was obtained from a wet acetonitrile solution. The multicomponent complexes 2 · 2(bpb) · MeCN (5) and 1 · (bpb) · 2MeOH (6) formed from self-assembly of 1,4-bis(4-pyridyl)butadiyne (bpb) with Cmethyl- resorcinarene (2) in acetonitrile and 1 in methanol, respectively. The structure of 5 reveals four symmetrical intermolecular O-H···N hydrogen bonds between 2 and bpb with two slightly distorted pyridine molecules, forming a wave-like chain polymer. A large extended cavity is built up to give a multicomponent molecular host which is filled with a solvent- and self-inclusion molecule as guests. The structure of 6 exhibits a pair of resorcinarene molecules side-connected to each other by two intermolecular O-H···O hydrogen bonds to form a 1D wave-like tape, which is further bridged by bpb with two perpendicular pyridines to form a 2D sheet.
