Abstract

We have prepared a series of thermotropic liquid-crystalline oligopeptide dimers based on dendritic oligo(glutamic acid)s. The synthesized oligopeptide dimers form thermally stable columnar liquid crystals. Self-assembled structures of the columnar liquid crystals varied with the spacer length and molecular chirality of the oligopeptide residues.
