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.

Fluorescence of excited ethynyl radicals produced by pulsed vacuum ultraviolet photolyses of C2H2, C2D2, and C2HBr
TL;DR: In this article, a broad fluorescence spectra of the ethynyl radical extending from 410 to wavelengths longer than 750 nm were found to be insensitive to parent molecules photolyzed, their pressures, and also pressures of an added gas, He.

Liquid-hexatic phase transitions in single molecular layers of liquid-crystal films
Robert E. Geer,T. Stoebe,Cheng-Cher Huang,Ron Pindak,John W. Goodby,Ming Cheng,John T. Ho,S. W. Hui +7 more
TL;DR: In this paper, the authors showed that a single liquid-hexatic transition in a two-layer film can be identified by heat capacity measurements, even in films just three layers thick.
Journal ArticleDOI
Liquid-crystalline ordering in the solution of semiflexible macromolecules
TL;DR: In this article, the conditions for formation of the liquid-crystalline phase in a solution of polymer macromolecules with steric repulsion between the parts of the polymer chains are determined by means of the Onsager method.

Layer Structure of Antiferroelectric Liquid Crystal MHPOBC Studied by X-Ray Diffraction
Atsushi Suzuki,Hiroshi Orihara,Yoshihiro Ishibashi,Yuichiro Yamada,Norio Yamamoto,Kahoru Mori,Koji Nakamura,Yoshiichi Suzuki,Takashi Hagiwara,Ichiro Kawamura,Minoru Fukui +10 more
TL;DR: In this paper, the authors studied the layer structure of the antiferroelectric liquid crystal MHPOBC and observed a thermal hysteresis, i.e., a chevron structure was formed in the cooling process and a bookshelf structure in the heating process.

A simple molecular theory of double reentrance exhibited by highly polar compounds
N. V. Madhusudana,Jyotsna Rajan +1 more
TL;DR: In this article, it was shown that dipole-induced dipole and interchain interactions lead to a parallel alignment of molecules with strong longitudinal dipoles for intermolecular separations below a certain value.
