3C06 分子両末端に炭素鎖を持つ化合物のスメクチックA相での分子配列に及ぼす炭素鎖の効果

抄録

The effect of alkyl and alkoxy chain lengths on the layer structure of smectic A phase has been examined by an X-ray diffraction measurement for four isomeric systems; 4-R-phenyl 4-(4-octyloxybenzoyloxy)benzoates (1), 4-octyloxyphenyl 4-(4-R-benzoyloxy)benzoate (2), 4-(4-R-benzoyloxy)phenyl 4-octyloxybenzoates (3) and 4-octyloxyphenyl 4-R-phenyl terephthalates (4), (R=alkoxy, alkyl). The results are discussed in terms of change in molecular properties due to replaccment of the ester groups.
