FT-IR and NMR studies on the conformational and structural properties of 1,2-dipalmitoyl-sn-glycero-3-phosphatidyloligoglycerols
Article Abstract:
An attempt is made to study the conformational behavior of membranes derived from a new class of phospholopids, 1,2-dipalmitoyl-sn-glycero-3-phosphatidyloligoglycerols DPPGx, using FT-IR spectroscopy in the liquid crystalline and gel state. The conformational and structural properties depend on the headgroup structure and hydrophilicity, sample composition as well as sample temperature.

Phase change in azobenzene derivative-doped liquid crystal controlled by the photochromic reaction in the dye
Article Abstract:
The results of kinetic studies of the isomerization of photochromic 4-fluoro-4'- methoxyazobenzene dissolved in the liquid-crystalline pentylcyanobiphenyl (5CB) are presented. A model relating to the kinetics of isomerization is put forward, which takes into account differences in the solubility of both forms in the liquid-crystalline matrix.

Conformational effect on macroscopic chirality modification of cholestric mesophases by photochromic azobenzene dopants
Article Abstract:
Azobenzenes having different positional substituents are dissolved in cholesteric liquid crystals to make cholesteric pitches tunable by photoisomerization. The differences in the conformations between the E- and Z-isomers of the azobenzenes are discussed to explain the observed characteristics.
