Formation of columnar mesophases by rod‐like molecules: Facial amphiphilic p‐Terphenyl derivatives

The liquid‐crystalline behavior of rod‐like mesogens is normally associated with the formation of smectic layer structures. However, it is shown that the introduction of large hydrophilic groups in a lateral position, such as in the Figure, can lead to columnar mesophases. The formation of columnar mesophases by rod‐like molecules is suggested to be a more general phenomenon than currently thought. magnified image
