“…[1][2][3][4] The most efficient and widely used approach for designing such material is the self-assembly of organic ligands and metal ions, and the type/topology of the products generated from this process can be tuned by a judicious choice of the ligands, [5][6] metal coordination geometry preference, counter ion, [6][7][8] solvent, [8][9] metal to ligand ratio [10][11] and temperature. 12 Among these, the choice of organic ligand is one of the important factors.…”

A dinuclear copper(II) complex of [Cu2(aceace)4(dipyph)] [aceace = acetylacetone, dipyph = 1,4-di(4-pyridylethene-2-yl-)benzene] has been synthesized and characterized by elemental analysis, IR and X-ray single crystal diffraction. It crystallizes in the monoclinic system, space group P21/c, with lattice parameters a = 7.9584(16) Å, b = 18.594(4) Å, c = 15.063(4) Å, β = 120.97 (2) o and Mr = 807.85 (C40H44Cu2N2O8), Z = 2. Each of the Cu 2+ ion adopts a square pyramid geometry and coordinates with four oxygen atoms from two aceace ligands and one nitrogen atom from dipyph bidentate ligand. Magnetic measurement shows that the Weiss constant and Curie constant for the title compound are -0.22 K and 0.1154 emu·K/mol, respectively. Thermal stability data indicate that the title complex undergoes two steps decomposition and the residue is Cu2O4. In the potential range of -1.5 ~ 0.8 V, the title complex represents an irreversible electrochemical process.

“…Of particular interest are structures that consist of conjugated polymers (CPs) because of their potential applications as, for example, anisotropic emitters and conductors [13]. From a supramolecular standpoint, Takeuchi and coworkers recently reported a supramolecular bundling approach toward the alignment of CPs [14]. The concept they have proposed resembles that found in animal cells where onedimensional actin filaments with high affinity elicit the formation of actin bundles.…”

The quest to understand the principle of weak noncovalent interactions such as hydrogen bonding, electrostatic interaction, van der Waals force, and so on has evoked intense research in supramolecular chemistry. Molecular contrivances with noncovalent interaction sites (molecular recognition sites) have straightforwardly led to chemosensors, artificial enzymes, topological molecules, and so forth [1]. In these systems, the noncovalent interaction sites are arranged so that they can converge on the guest molecule in consideration of the additivity and the complementarity of noncovalent interactions (convergent type recognition). In contrast, divergent type molecular recognition, when properly designed, can link the corresponding molecules together, and, particularly when complementary to themselves, they selfassemble to large objects [2]. The programmed direction and the number of noncovalent interactions define not only the size and shape but also the functions of these molecular assemblies; in fact, this adaptability permits vast applications in nanotechnology and materials science. Equally attractive are supramolecular polymers which have structures analogous to those of synthetic polymers, although the repeating units are linked via divergent-type noncovalent interactions [2c].Molecular assemblies and supramolecular polymers have led to a new horizon in advanced materials. The designed unit molecules and the resultant programmed assemblies of the supramolecular systems continue to offer new and exciting alternatives to conventional covalent bond-based synthetic polymers. The attractive advantages of the supramolecular systems are as follows: (1) reversible, recyclable and/or stimuli responsiveness, (2) flexible design of functions actualized by the program of direction and/or angle of noncovalent interactions (specifically, p-p stacking is an attractive characteristic for organic electronics), and (3) accessibility of nano-sized superstructures such as spheres, tubes, fibers, helices, and so on. From these viewpoints, the definition of polymers as opposed to small molecules could be becoming less meaningful, and molecular assemblies (i.e., supramolecular polymers) nowadays have a great influence on the design of functional materials.

“…Development in the field of supramolecular chemistry [1][2][3][4] and crystal engineering [5][6][7] during the last few decades is noteworthy, with a large number of applications in various fields of chemistry such as molecular recognition [8,9], sensors [10], catalysis [11], host-guest chemistry [12][13][14], surface patterning [15,16], electrical conductivity [17], molecular devices [18] and non-linear optics [19]. However the full potential of this branch of chemistry is yet to be realized.…”
