“…In contrast, electrochemistry reveals that there is efficient communication between adjacent metal centres in the ground state. These results provide significant new insights into the design of metallopolymers containing 10 conjugated backbones for sensing applications ranging from electrochemical and photonic detection of nucleic acid and proteins to electroluminescent display devices.…”

“…Therefore, while a modest driving force exists for photoinduced electron transfer from the metal centres to the polymer backbone, 5 excited state electron transfer from the polymer to the ruthenium centres is thermodynamically uphill. Thus, it appears that the Forster overlap between the polymer backbone and the ruthenium centres and a weak driving force for photoinduced electron transfer allows both the polymer 10 backbone and the ruthenium centres to emit.…”

“…4,5 In particular, benzimidazole polymers are attractive since metal complexes can be coordinated to the polymer backbone opening up the possibility of site-to-site electron hopping as well as electron transfer mediated by the polymer backbone 30 itself. 6,7,8,9,10,11,12 These conjugated metallopolymers are attracting increasing attention because of their potentially widespread applications, 13,14,15,16,17,18 and significant attention has been paid to polymers containing poly(pyridyl) complexes of 35 ruthenium(II) and osmium(II). 19,20,21,22 These metal complexes confer attractive redox and photophysical properties on the polymer and different metal loadings can be prepared by simply varying the relative mole ratio of the reactants.…”

“…In particular, azo-containing photochromic organic compounds and azo-conjugated metal complexes have received much attention due to their possible applications in the area of photon-mode high-density information storage, photoswitching devices and optical computing [1][2][3][4]. On the other hand, azobenzene is one of the representative photochromic compounds with two geometric isomers, a trans form and a cis form [5][6][7].…”

The single crystal X-ray diffraction analysis of the title compound, C 14 H 14 N 2 O, reveals that an interesting intermolecular or extended structure (hydrogenbonded polymeric zigzag chains) is formed by linking its monomer units with O-H · · · N type intermolecular hydrogen bonds. The compound crystallizes in the monoclinic space group P2 1 /n with a = 5.8151(5) Å, b = 18.106(1) Å, c = 11.515(1) Å and β = 96.891 (7) • . In order to understand better its structural aspects in solid state, quantum chemical (PM3) calculations were performed on a part of the extended structure of the title compound containing ten monomers. To determine in vacuo conformational flexibility of the compound, molecular energy profile of the title compound was obtained with respect to a selected torsional degree of freedom and the pedal angle varied from − 180 • to + 180 • in every 10 • . The results from the computational study suggest that hydrogen-bonding properties in the crystal lattice is fundamental in determining the crystallographically observed conformation of the title compound.

The crystal and molecular structure of 2-methyl-4-(4-methoxyphenylazo)phenol have been determined by X-ray single crystal diffraction technique. The compound crystallizes in the monoclinic space group P2 1 /c with a = 9.7763(8) Å, b = 11.3966(8) Å, c = 11.9531(8) Å and β = 108.752(6) • . In addition to the molecular geometry from X-ray experiment, its optimized molecular structure has been obtained with the aid of PM3 semiempirical quantum mechanical method, and then the corresponding geometric parameters were compared with those of X-ray crystallography. To determine conformational flexibility and crystal packing effects on the molecules, molecular energy profile of the title compound was obtained with respect to two selected degrees of torsional freedom, which were varied from −180 • to +180 • in steps of 10 • . Crystal structure of the title compound is a fibroid structure constructed by C-H···O and O-H···N type intermolecular hydrogen bonds. The most favorable conformer of the title compound has been determined by the crystal packing effects and there is no
