A supramolecular system for quantifying aromatic stacking interactions

A supramolecular complex for investigating the thermodynamic properties of intermolecular aromatic stacking interactions has been developed. The conformation of the complex is locked in a single well-defined conformation by an array of H-bonding interacti

Liquid crystalline 2-thienyl-4,6-diamino-1,3,5-triazines exhibiting Im3m and Pm3n micellar cubic phases in an inverted sequence

Two micellar cubic phases with different structures were observed for the first time in the order Im3m-Pm3n in a thermotropic phase sequence of 4,6-diaminotriazine terminated rod-like liquid crystals upon increasing alkyl chain length or rising temperatur

Self-assembly of imidazolium-based rodlike ionic liquid crystals: transition from lamellar to micellar organization

By using aryl-amination chemistry, a series of rodlike 1-phenyl1H- imidazole-based liquid crystals (LCs) and related imidazolium-based ionic liquid crystals (ILCs) has been prepared. The number and length of the C-terminal chains (at the noncharged end of the rodlike core) and the length of the N-terminal chain (on the imidazolium unit in the ILCs) were modified and the influence of these structural parameters on the mode of self-assembly in LC phases was investigated by polarizing microscopy, differential scanning calorimetry, and X-ray diffraction. For the single-chain imidazole derivatives nematic phases (N) and bilayer SmA2 phases were found, but upon increasing the number of alkyl chains the LC phases were lost. For the related imidazolium salts LC phases were preserved upon increasing the number and length of the C-terminal chains and in this series it leads to the phase sequence SmA-columnar (Col)-micellar cubic (Cuby1/Pm3n). Elongation of the N-terminal chain gives the reversed sequence. Short Nterminal chains prefer an end-to-end packing of the mesogens in which these chains are separated from the C-terminal chains. Elongation of the N-terminal chain leads to a mixing of N- and C-terminal chains, which is accompanied by complete intercalation of the aromatic cores. In the smectic phases this gives rise to a transition from bilayer (SmA2) to monolayer smectic (SmA) phases. For the columnar and cubic phases the segregated end-to-end packing leads to core-shell aggregates. In this case, elongation of the N-terminal chains distorts core-shell formation and removes Cub1 and Col phases in favor of single-layer SmA phases. Hence, by tailoring the length of the N-terminal chain, a crossover from taper-shaped to polycatenar LC tectons was achieved, which provides a powerful tool for control of self-assembly in ILCs.

Tuning the polarity of hierarchically assembled helicates

Catechol ligands bearing ester groups in 3-position (1a,b, 2) are building blocks for the formation of triply lithium-bridged dinuclear helicate-type complexes [Li1a,b,2)i-. Attachment of appropriate functionalities at the ester unit allows the fine tuning of the polarity of the compounds to afford solubility in highly nonpolar as well as highly polar solvents. The investigations show that the internal dinuclear core is stable in a broad variety of solvents, even in water. Georg Thieme Verlag Stuttgart ? New York.

Lipophilic thioglycosides for the Solution-Phase synthesis of oligosaccharides using biphasic Liquid-Liquid separation

A simple "heavy" lipophilic tag readily prepared from inexpensive gallic acid can greatly simplify the purification steps in oligosaccharide synthesis through liquid-liquid extraction (LLE) using two immiscible organic solvents. By introducing the tag at

Chemical triple-mutant boxes for quantifying cooperativity in intermolecular interactions

Chemical double-mutant cycles have been used to quantify intermolecular functional-group interactions in H-bonded zipper complexes in chloroform. If the same interaction is measured in zippers of different overall stability, the double-mutant cycles can b
