Saddle-shaped tetraphenylenes with peripheral gallic esters displaying columnar mesophases
Tetraphenylenes 2 with eight peripheral gallic esters were prepared in two steps from octamethoxytetraphenylene 1 in 19-72% yield. Investigation of the mesomorphic properties of 2 by DSC, POM and X-ray diffraction revealed that derivatives 2a-d with short alkoxy chain lengths (C(5)-C(8)) did not show any mesomorphic properties, whereas compounds 2e-i with C(9)-C(13) chains displayed rectangular...
متن کاملColumnar mesophases of hexabenzocoronene derivatives. I. Phase transitions.
Using atomistic molecular dynamic simulations we study the transitions between solid herringbone and liquid crystalline hexagonal mesophases of discotic liquid crystals formed by hexabenzocoronene derivatives. Combining a united atom representation for the side chains with the fully atomistic description of the core, we study the effect of side chain substitution on the transition temperatures ...
متن کاملFabrication of Saddle-Shaped Surfaces by Flame Forming Process
The flame forming process is widely used to manufacture ship hull plates. The saddle-shaped surfaces have different curvatures in perpendicular angles of planes and the manufacturers face an anti-clastic curvature. In this article, the manufacturing of saddle-shaped surfaces utilizing the flame forming process is investigated. The spiral irradiating scheme is used for forming. In order to study...
متن کاملColumnar mesophases from half-discoid platinum cyclometalated metallomesogens{{
A series of liquid crystals have been synthesized and studied based upon mononuclear orthoplatinated rod-like heteroaromatic and 1,3-diketonate ligands. The liquid crystalline properties of these molecules were investigated using polarized light optical microscopy, differential scanning calorimetry, single crystal X-ray diffraction, and powder X-ray diffraction. Increasing the number of alkyl c...
متن کاملFractional hoppinglike motion in columnar mesophases of semiflexible rodlike particles.
We report on single-particle dynamics of strongly interacting filamentous fd virus particles in the liquid-crystalline columnar state in aqueous solution. From fluorescence microscopy, we find that rare, discrete events take place, in which individual particles engage in sudden, jumplike motion along the main rod axis. The jump length distribution is bimodal and centered at half- and full-parti...
