Phase achiral complexes observed behavior with benzene rings in the core areasA chiral A-Ph6 the expressed liquid in a narrow temperature range, new compGold complexes S-Ph6 did not develop liquid. A typical liquid crystal molecules is a rigid core partsAnd with flexible side chains, but it does not have only one benzene ring A-Ph6 and S-Ph6,Could not be expressed enough rigid core sites, stable liquidI thought. We design and core parts in the longitudinal direction elongated gold complexes A-Bi6 and S-Bi6With time, showed a enanthiothro pick liquid crystalline complexes of these gold complexesLiquid temperature range exists at the high temperatures, very high melting point of A-Bi6 and S-Bi6. Gold complexesIn the body as liquid crystal materials in practical use, expressing the liquid at room temperatureThat is desirable. Compared to introduced the biphenyl skeleton with a benzene ring complexesObserved by a methyl group deploying flexible chain complexes of any significant decrease in melting pointIt was. Also, complexes having flexible chains achiral crystal structures from, length of core partsAnd to estimate the ratio of molecular long axis and minor axis direction, i.e. the aspect ratio (Figure 2-7),Correlation between aspect ratio and melting temperature, liquid temperature range was seen (Figure 2-8).

Phase transition results behavior has been observed, achiral complexes having a benzene ring in the core portion
but A-Ph6 expressed a liquid crystal phase in a relatively narrow temperature range, chiral was synthesized new
gold complex S-Ph6 the liquid crystalline It did not express. General liquid crystal molecules are rigid core sites
but with combination of the flexible side chain, A-Ph6 and S-Ph6 choice but no one benzene ring,
in order to rigidity of the core sites were not enough, I stable I could not express a liquid crystal phase
was considered. So the core site was designed gold complex A-Bi6 and S-Bi6 which was extended in the longitudinal direction
place was, but these complexes showed enantiotropic Toro pick liquid crystal, gold complex
is the melting point of the A-Bi6 and S-Bi6 very high, liquid crystal temperature range is present in the high-temperature region. Gold complex
in the case of practical use of the body as a liquid crystal material, to express a liquid crystal phase at around room temperature
is desirable. Comparing the complex obtained by introducing a benzene ring and a biphenyl skeleton,
a significant reduction in the melting point observed by introducing a methyl group into flexible strands in either the complex
is. In addition, from the crystal structure of the complex with achiral flexible chain, the length of the core site
axis and the short axis of the molecular length ratio of, that is, to approximate the aspect ratio (Figure 2-7),
the aspect ratio and the melting point, liquid crystal temperature correlation with ranges were observed (Fig. 2-8).

The results ， observed phase transition behavior ， expressed liquid crystal phase in a relatively narrow temperature range at the A complexes and achiral Ph 6 having a benzene ring in the core part of new chiral metal complexes synthesized at S Ph 6 expression and liquid crystal property. The liquid crystal molecules ， rigid flexible side chain and core part together with the general ， benzene ring due to lack of the core may be only one site 3h-prolin and rigid, but A Ph -- 6 -- 6 S Ph stable and can not be expressed by liquid crystal phase.， gold complexes and A Bi -- 6 -- 6 S Bi design at the core portion extending in the longitudinal direction in these complexes showed ， Enantiotropic liquid crystal and gold complexes at the melting point of the Bi A -- 6 -- 6 S Bi very high ， existed in high temperature region of the liquid crystal temperature range. ， when practically used as a liquid crystal material and a gold complex body at near room temperature, it is desirable to expression at the liquid crystal phase. A benzene ring with biphenyl backbone and compare 3h-prolin complexesIn any of the complex observation at the melting point to a significant reduction of introducing a methyl group in the flexible chain. The ， the crystal structure of the complexes with flexible chain ， achiral molecule of the length of the length in the axial direction of the core at the site and the short axis direction and the ratio ， is estimated and the aspect ratio (Fig. 2-7 25asb-2 melting temperature range of the aspect ratio of the liquid crystal ， correlation can be seen in Fig. 8 (2)).
