Relevant academic research and scientific papers

Rigid phenylene ethynylene units linked by a V-shaped centre. An approach to biaxial nematogens?

Encouraged by theoretical predictions that nematic phases formed from V-shaped compounds could be biaxial, shape-persistent phenylene ethynylene arms linked by 1,3-phenylene, 4,4′-diphenylenemethane and 3,6-fluorenone units have been synthesized. Crystall

Preparation and nonlinear optics of monodisperse oligo(1,4-phenyleneethynylene)s

Oligo(1,4-phenyleneethynylene)s 1a-e, with solubilizing propoxy side chains, were prepared by use of Hagihara-Sonogashira coupling reactions. The synthetic strategy was based on a building block system and on the use of trimethylsilyl and triisopropylsily

Synthesis, aggregation, and adsorption phenomena of shape-persistent macrocycles with extraannular polyalkyl substituents

The synthesis of shape-persistent macrocycles based on the phenyl-ethynyl backbone containing various extraannular alkyl side chains is described. Although compound solubility increases with increasing size of the side groups, decreasing the solvent polar

Soluble ferrocene conjugates for incorporation into self-assembled monolayers

A series of phenylethynyl oligomers (I-V) possessing a ferrocene and thiol at each termini have been synthesized. These oligomers have been designed to overcome the inherent insolubility of this class of complexes by substitution at the phenyl groups with methyl and propoxy substituents. Several new reactions for preparing arenethiol-protected compounds are described. Interestingly, the generation of an arenethiol anion during base- or fluoride-catalyzed deprotection has been characterized.
