A quasi-bookshelf layer structure has been obtained by a conventional rubbing method at room temperature in a FLC mixture composed of naphthalene-derived liquid crystals. This layer structure is spontaneously formed due to a unique temperature dependence of the interlayer spacing; X-ray diffraction indicates that the layer spacing decreases from 34 to 33.5 Å and then increases to 33.8 Å with decreasing temperature in SmC*. Contrary to the unusual behavior of the layer spacing, the director tilt angle determined optically shows ordinary temperature dependence and attains a relatively large value, 17°, at room temperature.

Both bookshelf and quasi-bookshelf layer structures are obtained by using naphthalene base liquid crystal mixture with a rubbed polymer orientation films panel. This panel shows a high contrast ratio reaching at 351 and high transmittance of 40% driven by multiplexing method.

Eight different 1:1 charge-transfer(CT) complexes were prepared using tetrahydrobarreleno-tetracyanoquinodimethane(THBTCNQ), dihydrobarreleno-tetracyanoquinodimethane(DHBTCNQ), monobenzobarreleno-tetracyanoquinodimethane(MBBTCNQ), and dibenzobarreleno-tetracyanoquinodimethane(DBBTCNQ) as tetracyanoquinodimethane(TCNQ)-type acceptors, and tetrathiafulvalene(TTF), bis(tetramethyene)-tetrathiafulvalene(OMTTF), and tetramethyl-tetrathiafulvalene(TMTTF) as TTF-type donors. The complexes can be classified into three distinct groups, I–III, on the basis of the magnitude of both the degree of CT and the electrical resistivity of compacted powders. Group-I complexes are characterized by a small band gap semiconductivity and moderate CT, group-II complexes by low conductivity and small CT, and group III complexes by low conductivity and complete CT. The stacking mode of the three groups of complexes are discussed, by comparing the electronic absorption spectra of the three groups of CT complexes with those of the complexes for which the crystal structures are known. A crystal structure analysis of OMTTF–DBBTCNQ revealed that it is the first example of a highly ionic CT complex of a TTF–TCNQ type with a regular mixed stacking mode. These three groups of complexes containing bulky acceptor groups will be of theoretical interest in studying the crystal properties of organic CT complexes.

A full description of the rotatable high-pressure glass cell method for the NMR measurements is presented. This simple device eliminates the use of massive high-pressure apparatus such as the oil pump, the Bourdon gauge, and the high-pressure tubing and valves in performing the high-pressure experiments. This system also demonstrates capability of realizing an extremely high-resolution level in the NMR measurements at high pressure otherwise not easily attainable.
