A redox-switchable [2]rotaxane in a liquid-crystalline state.
Redox-driven mechanical movement, which has been achieved for a liquid-crystalline (LC) bistable [2]rotaxane in the LC phase, is accompanied by obvious electrochromism (electrochemically induced changes in color) of the material. The dumbbell-shaped LC [2]rotaxane with redox-active moieties, which interlocks with an ionic macrocycle, forms ordered redox-active condensed states.
متن کاملLiquid Crystalline Water, Quantum Molecular Machines & the Living State
It has been 18 years since the discovery in my laboratory suggesting that living organisms are dynamic liquid crystalline phases in which all the molecules in the cells and tissues of the body are aligned and moving coherently together, including especially the water molecules that are intrinsic to the liquid crystalline matrix and essential to the function of macromolecules. In effect, the org...
متن کاملSupercooled-liquid and plastic-crystalline state in succinonitrile-glutaronitrile mixtures.
We report a thorough characterization of the glassy phases of mixtures of succinonitrile and glutaronitrile via dielectric spectroscopy and differential scanning calorimetry. This system is revealed to be one of the rare examples where both glassy states of matter, a structurally disordered supercooled liquid and an orientationally disordered plastic crystal, can be prepared in the same materia...
متن کاملLiquid-crystalline terpyridines.
5,5"-Disubstitution of the terpyridine core leads to the first inherently liquid-crystalline terpyridines. Mesophases characteristic of bent-core and calamitic systems may be obtained depending on the core structure employed.
متن کاملLiquid crystalline crown ethers.
In this chapter, a comprehensive review over the entire reserarch on liquid crystalline crown ethers since their discovery will be given. Monomeric and polymeric molecules containing crown ethers as well as aza crown ethers, thia crown ethers and crown ethers with several different heteroatoms will be presented. Liquid crystallinity is, in most cases, caused by the substituents attached to the ...
