Аннотация:
In search of a substance able to function as an anionic surfactant applied for the electrically-induced anchoring transitions in liquid crystals, the compound 4-heptyloxybenzoate benzyl dodecyldimethylammonium (HOBBDDA) has been synthesized. Its orienting influence on
nematic
liquid crystal 4-pentyl-4'-cyanobiphenyl (5CB) has been tested. HOBBDDA dissolved up to 1.4%in 50 droplets dispersed in polymer film does not change the tangential surface anchoring inherent to polyvinyl alcohol matrix used. Homeotropic surface anchoring is realized if the HOBBDDA content exceeds 1.7%. The molecules of the surfactant in 5CB dissociate into anions and cations. The anions modify the surface anchoring under the action of DC electric field both in the normal and inverse mode. The mixture of HOBBDDA and cetyltrimethylammonium bromide can function as a binary ionic cationic surfactant which significantly expands the prospects for using the ionic-surfactant method to control liquid crystal materials.

Аннотация:
The orientational order parameter S of molecules in high-temperature discotic
nematic
liquid-crystal phases of triphenylene derivatives is investigated as a function of the length of side flexible molecular chains at different temperatures. It is established that the orientational order parameters S in the range of the transition from the
nematic
phase to the isotropic liquid phase (the N-D-I transition) are smaller than those predicted from the molecular-statistical theory and computer simulation. It is shown that the N-D-I transition is close to both the isolated Landau point and the tricritical point (regardless of the chemical structure of the molecules and the anisotropy of dispersion intermolecular interactions). Consistent explanations are offered for a number of experimental findings, such as the anomalously small changes in the enthalpy and entropy upon the N-D-I transition (as compared to those revealed upon the N-I transition in calamitic
nematic
liquid crystals), the anomalously strong response of the isotropic phase of discotic
nematic
liquid crystals to external fields (thermodynamically conjugate to the order parameter S) and the long relaxation times of this response, and the formation of cybotactic discotic molecular clusters in the isotropic phase in the vicinity of the N-D-I transition.

Аннотация:
Homogeneous thermal fluctuations of the orientational order parameters S and G of biaxial molecules in a uniaxial
nematic
liquid crystal are investigated in the framework of the molecular-statistical theory. It is demonstrated that the molecular biaxiality significantly affects the order parameters S and G, their temperature dependences in the
nematic
phase, the amplitude and the temperature dependence of the order parameter fluctuations in the
nematic
and isotropic phases, and the character of the transition from the
nematic
phase to the isotropic liquid phase. It is established that the fluctuations of the parameters S and G in the
nematic
phase are related to the temperature dependences of S and G and the susceptibilities chi(S) and chi(G) of the
nematic
liquid crystal to external fields, which leads to a change in the parameters S and G at a fixed director orientation. Explanations are offered for the known experimental data on the orientational ordering of biaxial molecules under the action of external fields in the isotropic phase of
nematic
liquid crystals. (C) 2003 MAIK "Nauka/Interperiodica".

Аннотация:
Experimental values of the polarizability tensor gamma components of molecules of ethyl-p-(4-ethoxybenzylideneamino-)alpha-methyl cinnamate liquid crystals in the
nematic
and smectic A phases have been obtained. Quadratic dependences of the longitudinal, gamma (l) , and transverse, gamma (t) , components, the mean value , and anisotropy Delta gamma in both phases have been established as functions of the orientational order parameter S of molecules in a maximally wide range of S. The
nematic
-smectic A phase transition with a continuous variation of S manifests itself as kinks in the linear dependences of , Delta gamma, and gamma (l) on S (2) and does not influence the dependence gamma (t) (S (2)). The observed dependences have been derived in the framework of the theory of the
nematic
-smectic A phase transition. The factors responsible for different influences of the orientational and positional orderings of molecules on the polarizability parameters have been determined.

Аннотация:
The problems on the relation of the mean effective molecular polarizability (gamma) over bar to the long-range orientational order of molecules (the optical anisotropy of the medium) in uniaxial and biaxial liquid crystals, the local anisotropy on mesoscopic scales, and the anisotropy of the Lorentz tensor L and the local-field tensor f are formulated and solved. It is demonstrated that the presence of the long-range orientational order of molecules in liquid crystals imposes limitations from below on the molecular polarizability (gamma) over bar, which differs for uniaxial and biaxial liquid crystals. The relation between the local anisotropy and the molecular polarizability (gamma) over bar is investigated for calamitic and discotic uniaxial liquid crystals consisting of lath- and disk-shaped molecules. These liquid crystals with identical macroscopic symmetry differ in the local anisotropy and the relationships between the components L(parallel to)
L(perpendicular to,) f(parallel to) > f(perpendicular to) (discotic) for an electric field oriented parallel and perpendicular to the director. The limitations from below and above on the molecular polarizability (gamma) over bar due to the anisotropy of the tensors L and f are established for liquid crystals of both types. These limitations indicate that the molecular polarizability (gamma) over bar depends on the phase state and the temperature. The factors responsible for the nonphysical consequences of the local-field models based on the approximation (gamma) over bar = const are revealed. The theoretical inferences are confirmed by the experimental data for a number of calamitic
nematic
liquid crystals with different values of birefringence and the discotic liquid crystal Col(ho).

Аннотация:
The polarized electronic absorption spectra, orientation ordering, and the special local field features were studied for push-pull linear dye molecules with strong donor-acceptor electronic conjugation of terminal fragments in the matrix of a
nematic
liquid crystal. The temperature-induced inversion of the sign of the splitting of polarized impurity absorption bands was observed. This effect was shown to be caused by the statistical character of orientation ordering of impurity molecules and manifestation of the higher moments of the orientation distribution function. The dependence of local field parameters (Lorentz tensor components) of impurity molecules on their orientation ordering was established. This dependence was used to reproduce the temperature dependence of the orientation order parameter of the matrix. (C) 2004 MAIK "Nauka / Interperiodica".

Experimental values of the mean polarizability of molecules, (gamma) over bar, and components of the Lorentz tensor, L-j, in the
nematic
and smectic A phases are obtained for a homologous series of n-alkyl-p-(4-ethoxybenzylideneamino)-alpha-methylcinnamates. Dependences of the (gamma) over bar and L-j values on the mesophase temperature, the orientational order parameter S of molecules, and the number n in the homologous series are revealed. The quadratic dependence of (gamma) over bar (S) in the
nematic
and smectic phases is established that is invariant with respect to the
nematic
-smectic A transition. Polarizability densities of the molecular core and the alkyl chain are found from the monotone decreasing dependence (gamma) over bar (n)/v (where v is volume per one molecule) in the smectic phase. The presence (or absence) of the odd-even alternation of L-j(n) in the
nematic
(smectic) phase is shown. A monotone decrease in the Lorentz tensor anisotropy L with an increase in n is revealed in the smectic phase, and limiting values L-j(n -> infinity) are determined.

This paper discusses how the features of the local symmetry of calamitic and discotic
nematic
liquid crystals, the orientational ordering of the molecules, the polarization of intramolecular transitions, and the resonance intermolecular interactions (local-field effects) affect the polarized absorption spectra of these objects. It is shown that the difference of the local symmetry of calamitic and discotic nematics manifests itself in observable qualitative differences in their spectral properties.

Аннотация:
The interaction of the conformational degrees of freedom of azomethines in the
nematic
phase, which is induced by electronic donor-acceptor properties of the terminal substituents of the benzylideneaniline core is studied. These degrees of freedom related to the rotation angles phi (k) around the bonds between the substituent and the aniline ring (phi(1)) and also between the CH=N bridge and the aniline ring (omega(2)) are characterized by the parameters Q (k) = aOE (c) cos(2)phi (k) >. It is found that the interaction of these degrees of freedom is manifested in the linear dependence Q (2)(Q (1)). Within the phenomenological theory the effect of this interaction on changes delta (k) in the Q (k) values during the
nematic
liquid crystal-isotropic liquid phase transition is revealed along with the temperature T (NI) and character of this transition. The derivation of previously established empirical dependences T (NI)(Q (k) ) is presented in the presence of direct and indirect steric effects of side substituents affecting the Q (k) values. A diverse combination of delta (k) signs in the
nematic
phase, which is a prerequisite for the conformational polymorphism of the
nematic
phases of azomethines, is shown.

Аннотация:
A new approach is proposed for interpreting the polarized fluorescence spectra of an impure liquid crystal in which the orientational order of excited impurity molecules has undergone relaxation. This approach has also been realized experimentally. The new experimental data demonstrate a new relaxation process with a time scale on the order of 10(-11)-10(-9) s.

Аннотация:
First experimental data on the orientational order of the molecules in a discoid
nematic
liquid crystal are reported. These results are dramatically at odds with the results of a numerical simulation for rigid disk-shaped molecules. The N-D-I phase transition is simultaneously close to an isolated Landau critical point and to the tricritical point, as in ordinary calamite
nematic
liquid crystals with Planckian molecules. This result indicates that conformational degrees of freedom of the molecule play an important role in the features of the N-D-I transition. (C) 1995 American Institute of Physics.
