“…Therefore, the C À H···Br À interaction is affected more by the solvent than the C À H···I À interaction. Concerning the energetics of the formation of the Mo complexes, our results for the gas-phase Gibbs energy (DG gas ) for reaction (1) shows that the formation of [Mo] + Br À is 5.6 kcal mol À1 more favored than [Mo] + I À . The presence of one and two CH 2 Cl 2 molecules [reactions (2) and (3)] reduces this value to 3.5 and 2.0 kcal mol À1 , respectively.…”

“…Stable supramolecular adducts were formed in the reactions of 1·BAr' 4 and 2·BAr 4 with bromide, iodide, hydrogensulfate, and methanesulfonate compounds. The binding constants of these adducts in dichloromethane were calculated from 1 H NMR spectroscopic titration data, and the solid-state structures of the 1·Br, 1·HSO 4 , 1·I, and 2·I adducts were determined by X-ray diffraction studies. The surprising slightly higher stability of the iodide adduct relative to that of bromide was investigated theoretically, with the results pointing to an effect of the differential solvation of the halide ions.…”

“…[50] On the other hand, if a molecular stack lacks this kind of long-range interaction, then the stabilization gained by the stack is purely local, arising from interaction with the nearest neighbours, and this contribution remains more or less constant throughout the course of polymerization. Thus, when another molecule is added to such an existing stack or aggregate, it (the added molecule) can interact with not only its nearest neighbours but also with the molecules distant from it, thus leading to a greater stabilization of the aggregate.…”

“…[1] Um funktionelle Eigenschaften präzise einstellen zu kçnnen, bençtigt man wohldefinierte hierarchisch geordnete supramolekulare Materialien. [4][5][6][7][8][9] H-Bindungen werden gebildet, wenn ein Donor mit saurem Wasserstoffatom mit einem Akzeptor, der ein nichtbindendes freies Elektronenpaar trägt, wechselwirkt. [2,3] Wasserstoffbrücken (H-Brücken) sind ideale nichtkovalente Wechselwirkungen zum Aufbau supramolekularer Architekturen, weil sie hoch selektiv und gerichtet sind.…”

“…In dieser Hinsicht hat sich die Selbstorganisation von Flüssigkristallen als ein extrem nützliches Werkzeug für die Entwicklung von wohldefinierten nanostrukturierten Materialien erwiesen. [4][5][6][7][8][9] Flüssigkristalle (LCs) kçnnen in verschiedenen Phasen wie smektischen und nematischen Phasen existieren, die sich im Grad der lateralen Orientierungs-und Rotationsausrichtung der Moleküle unterscheiden (Abbildung 1). [4][5][6][7][8][9] H-Bindungen werden gebildet, wenn ein Donor mit saurem Wasserstoffatom mit einem Akzeptor, der ein nichtbindendes freies Elektronenpaar trägt, wechselwirkt.…”
