Benzene rings 1 and 4 positions, biphenyl skeleton 4 position and 4 'position, naphthalene ring 2
was the distance of the position and the 6-position of the carbon and molecular length of the long axis. The 5 from third place in the benzene ring
position, biphenyl skeleton 3 'place from the 5' position, naphthalene ring is directed to the carbon of position 8 from the 4-position
draw a vertical line to Ke, the aspect ratio the distance as the molecular length of the short axis It was calculated. Figure
from 2-8, S-Ph6 with small benzene ring aspect ratio (aspect ratio 1.2)
does not exhibit a liquid crystal phase but it was found to have a relatively low melting point. On the other hand, Aspect
S-Bi6 which introduced a large biphenyl skeleton of the defect ratio (aspect ratio 3.0) is lowered over
were found to express the N * phase in a wide temperature range of about 100 ° C in degree. Accordingly,
naphthalene ring (aspect ratio 1.7) having an intermediate aspect ratio of these complexes
are chiral S-Nap6 having, can express N * phase at around room temperature and a wide range of temperatures
was think molecular skeleton Ru. This complex S-Nap6 initially as expected, Enanchiotoro
shows a pick liquid crystallinity, expressed the N * phase to around room temperature in the cooling process. The binding
phase transition behavior of the complex from the results is strongly influenced by the structure of the aspect ratio and the flexible chain of the core portion
was found to undergo.
