The first single‐diamond cubic phase in a liquid crystal is reported. This skeletal structure with the
space group is formed by self‐assembly of bolaamphiphiles with swallow‐tailed lateral chains. It consists of bundles of π‐conjugated p‐terphenyl rods fused into an infinite network by hydrogen‐bonded spheres at tetrahedral four‐way junctions. We also present a quantitative model relating molecular...
Stabförmige Mesogene (siehe Schema) mit Schwalbenschwanz‐artigen Seitenketten ordnen sich axial zu bänderförmigen Bündeln an. Bei hoher Temperatur rotieren die Bänder unter Bildung einer neuartigen hexagonalen 3D‐Flüssigkristallphase (siehe Bild, links). Bei niedrigerer Temperatur stoppt die Rotation, und man erhält eine Struktur aus gekreuzten aromatischen und fluorierten Säulen (rechts). Bei weiterer...
