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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.

Generalized Landau model of ferroelectric liquid crystals.
TL;DR: A generalized Landau type of free-energy density is developed, which, in a unified way, describes the general features of the tilt, polarization, pitch, dielectric susceptibility, and heat capacity of ferroelectric liquid crystals.
Journal ArticleDOI
X-Ray Study and Microscopic Study of the Reentrant Nematic Phase
TL;DR: In this article, x-ray experiments on mixtures of N-($p$-hexyloxybenzylidene)-$ p$-aminobenzonitrile (HBAB) in N-$p$ -cyanobenzyloxybiphenylidsene-$ p$-$n$-octloxyaniline (CBOOA) are reported.

Density functional approximation for hard‐body liquid crystals
A. M. Somoza,Pedro Tarazona +1 more
TL;DR: In this paper, a density functional approximation for the free energy of a system of hard bodies with arbitrary shape and orientational distribution is presented, which reduces to existing treatments, which describe the isotropic liquid and the nematic liquid crystal.
Journal ArticleDOI
The freezing of hard spheres: The density functional theory revisited
Marc Baus,Jean-Louis Colot +1 more
TL;DR: In this article, the theory of freezing was reconsidered starting from formally exact equations, making three physical approximations and testing all numerical methods for the case of the freezing of hard spheres.
Journal ArticleDOI
A molecular‐statistical theory of the temperature‐dependent pitch in cholesteric liquid crystals
TL;DR: In this paper, an interaction between chiral molecules is derived in terms of the orientations of their long molecular principal axes, in analogy with Maier-Saupe and Goossens the derivation is based on the electric multipole expansion.
