Details of the transitional properties of four homologous series of U-shaped liquid crystal materials, the benzene-1,2-di-(4-carboxyalkoxybenzylidene-4-n-alkylanilines), are presented. The spacers incorporate 3 to 6 methylene units, whilst terminal a

The observation of language-like features in non-coding DNA has led to suggestions that "junk" DNA could have higher-order functions, possibly associated with controlling gene expression. We propose a physically realistic model which provides an insi

A series of side-chain liquid crystal copolymers have been prepared based on a polystyrene backbone and having 4-nitro-4′-oxyazobenzenealkyloxy and 4-methoxy-4′-oxyazobenzenealkyloxy pendant groups. All the polymers exhibit solely smectic behavio

The thermotropic mesomorphism of tetrakis(μ-(2,2-(dioctyl(acetato))-O,O′)bis-[copper(II)] has been investigated by optical microscopy and X-ray diffraction. This compound was found to form a hexagonal discotic phase analogous to those reported for

The dielectric relaxations and the optical transmission of a carefully purified liquid crystalline side chain polysiloxane have been measured in the isotropic and the nematic phases, and an apparent hysteresis has been found in the biphasic region du

Lead(II) salts of aliphatic diacetylenic carboxylic acids are found to form highly ordered smectic phases which thermodynamic data indicate are similar to those reported for the saturated lead(II)alkanoates. At room temperature the materials exist as

It is shown that cooling a partially homeotropically aligned liquid crystalline siloxane polymer from the biphasic region into the liquid crystalline (l.c.) region leads to homeotropic alignment of the phase in the absence of a directing electric fie

A theory for the dielectric relaxation behaviour of a partially aligned liquid crystalline (LC) material is described. It is shown, quite generally, that the complex dielectric permittivity may be expressed in terms of the parallel (ϵ‖) and perpen
