Modulated SmA(b) phases formed by anchor shaped liquid crystalline molecules.

Bent-core molecules with a linear alkyl chain in the bay position (anchor shaped molecules) form new liquid crystalline phases combining periodicities with different coherence lengths in distinct directions; in these LC phases the molecules are organized on average orthogonal in modulated layers (ribbons or patches) with restricted rotation around the long axis, thus representing modulated SmA(...

Optical studies of the liquid crystal B2 phase formed by banana-shaped molecules.

Null-transmission ellipsometry and depolarized light microscopy have been performed on free-standing films of three achiral banana-shaped compounds in the B2 phase. Our results support a two-layer unit cell previously proposed to explain the observed antiferroelectricity in thin films and bulk samples. We have studied thicker films than previously reported and have found no deviations in the fi...

Flexoelectric Effects in Liquid Crystals Formed by Pear Shaped Molecules. A Computer Simulation Study

where e11 and e33 denote the flexoelectric coefficients related to splay and bend distortions, respectively. The phenomenon is somewhat similar to the piezoelectric effect in certain solid crystals where a coupling between mechanical stress and polarization is observed, so that the polarization manifests itself due to a positional deformation. The flexoelectric effect has attracted a great deal...

Liquid-crystalline supramolecular polymers formed through complementary nucleobase-pair interactions.

We report how the placement of nucleobase units, thymine, or N6-(4-methoxybenzoyl)adenine, onto the ends of a mesogenic core, bis-4-alkoxy-substituted bis(phenylethynyl)benzene, affects the properties of these materials. We show that addition of these bulky polar groups significantly reduces the range of liquid-crystalline behavior of these compounds. However, mixing two complementary nucleobas...
