…When molecules in cholesteric liquid crystals are stacked, they twist to the right or left. This phenomenon is due to the asymmetry of the molecules, and is due to the presence of atomic groups that give them the twist. Such molecules are called chiral molecules. By mixing a small amount of cholesteric liquid crystal with nematic liquid crystal, it is possible to create a state called chiral nematic, with a pitch of several micrometers. … *Some of the terminology that mentions "chiral molecules" is listed below.

…コレステリック液晶では分子を重ねると右または左にねじれていくが,このような現象は分子の非対称性に由来するものであり,ねじれを与える原子団があるためである。そのような分子をカイラル分子と呼ぶ。ネマティック液晶にコレステリック液晶をわずかに混合すると,ピッチが数μmのカイラルネマティックと呼ぶ状態を作り出すことができる。… ※「カイラル分子」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
