Phase Transformations in Chiral Non-racemic Main-chain Liquid Crystalline Polyesters Involving Double-twist Helical Crystals
It is for the first time the double-twisted helical single lamellar crystals were observed in a series of synthetic chiral non-racemic main-chain liquid crystalline polyesters. Phase structure and transition behaviors were investigated. Multiple liquid crystalline phases were found including the twisted grain boundary phase. During crystallization, the chain molecules kept their memory of the p...
متن کاملPolarization holographic gratings in side-chain azobenzene polyesters with linear and circular photoanisotropy.
We investigate thin phase polarization holographic gratings recorded with two waves with orthogonal linear polarizations in materials in which illumination with linearly/circularly polarized light gives rise to linear/circular birefringence. The theoretical analysis shows that the presence of circular photoanisot-ropy changes significantly the diffraction characteristics of the gratings. The in...
متن کاملN ematic and Cholesteric Thermotropic Polyesters with Azoxybenzene Mesogenie Units and Flexible Spacers in the Main Chain
Properties of linear polyesters based on azoxybenzene and 2,2'-methylazoxybenzene moieties with linear, flexible spacers based on mixtures of dodecanedioic acid (DDA) and methyladipic acid (MAA), chiral or racemic, of various compositions (system MAA/DDA-8 and MAA/DDA-9, respectively) have been described. Substitution of methyl groups in the 2,2' or 3,3' positions of the mesogenic core Ieads to...
متن کاملnon-linear study of various slit shear walls in steel structures
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
15 صفحه اولSide-chain liquid-crystalline polyesters for optical information storage.
We report erasable holographic recording with a resolution of at least 2500 lines/mm on unoriented films of sidechain liquid-crystalline polyesters. Recording energies of approximately 1 J/cm(2) have been used. We have obtained a diffraction efficiency of approximately 30% with polarization recording of holograms. The holograms can be erased by heating them to approximately 80 degrees C for app...
