Towards in silico liquid crystals. Realistic transition temperatures and physical properties for n-cyanobiphenyls via molecular dynamics simulations.
TL;DR: By using the united-atom force field developed herein, it is shown that the experimental isotropic-nematic transition temperatures are reproduced within 4 K, allowing a molecular-level interpretation of the odd-even effect along the series.

Structure And Thermodynamics of Weakly Segregated Rod-Coil Block Copolymers
TL;DR: In this paper, the selfassembly of a series of monodisperse rod−coil block copolymers is studied in the weak segregation limit, and the order to microphase disorder transition (ODT) and nematic isotropic (NI) transition are experimentally investigated.

Mechanochromic luminescence of halide-substituted difluoroboron β-diketonate dyes
TL;DR: In this paper, the effects of halide substituents on mechanochromic luminescence quenching were investigated for a series of difluoroboron β-diketonate (BF2bdk) compounds.

Universalization of the Phase Diagram for a Model Rod-Coil Diblock Copolymer
TL;DR: In this paper, the Flory−Huggins interaction is measured for a model rod-coil block copolymer system, poly(alkoxyphenylenevinylene-b-isoprene), by fitting the interfacial segregation of block copolerant to a homopolymer interface and by using the random phase approximation (RPA) for block co-olymers.
Journal ArticleDOI
Insight into entropy
TL;DR: In this article, the qualitative character of entropy has been investigated and several examples from statistical mechanics (including liquid crystal reentrant phases, two different lattice gas models, and the game of poker) demonstrate facets of this difficult question and point toward an answer.

Paramagnetic nematic liquid crystals
TL;DR: In this paper, the authors reported new nematic liquid crystals that are paramagnetic, which they termed paramagnetic liquid crystals (PLCs), and they used them to construct paramagnetic lattice.
Journal ArticleDOI
Molecular statistical calculation of pretransitional effects in nematic liquid-crystals
TL;DR: In this article, a molecular statistical treatment is given of two pretransitional effects in the isotropic phase of nematic liquid crystals, namely magnetically induced birefringence and the scattering of light by orientational fluctuations.
Journal ArticleDOI
Free energy of an assembly of nonspherical molecules with a hard core
TL;DR: In this article, the free energy of an assembly of slightly nonspherical molecules with a hard core is expressed as the sum of the free energies of a system of equivalent hard spheres plus correction terms related to eccentricity, and an estimate of these terms is made for ellipsoidal molecules.
Journal ArticleDOI
Reentrant nematic and columnar phases in disc-like liquid crystals at atmospheric pressure
TL;DR: In this paper, the authors describe the first example of reentrant ND nematic and columnar mesophases at atmospheric pressure in a pure disc-like compound, and present an example of columnar ND mesophase at the same pressure.
