The single gyroid phase as well as the alternating double network gyroid, composed of two alternating single gyroid networks, hold a significant place in ordered nanoscale morphologies for their potential applications as photonic crystals, metamaterials and templates for porous ceramics and metals. Here, we report the first alternating network cubic liquid crystals. They form through self-assembly of X-shaped polyphiles, where glycerol-capped terphenyl rods lie on the gyroid surface while semiperfluorinated and aliphatic side-chains fill their respective separate channel networks. This new self-assembly mode can be considered as a two-color symmetry-broken double gyroid morphology, providing a tailored way to fabricate novel chiral structures with sub-10 nm periodicities using achiral compounds.

No place like kagome: A quaternary amphiphile displays a novel complex liquid-crystalline phase formed by a periodic array combining triangular and hexagonal cylinders, filled with hydrocarbon and fluorinated chains, respectively. This leads to a fluid nanoscale multicompartment structure with kagome geometry. The thickness of the intercompartment walls is equal to the width of the π-conjugated rods (shown as black lines).

The synthesis of a ditopic 2,2′:6′,2″-terpyridine ligand and bis-ruthenium(II) complex is described which incorporates in its molecular backbone a light-activated spiropyran moiety.
