title: Formation of a Cubic Liquid Crystalline Nanostructure with π-Conjugated Fluorinated Rods on the Gyroid Minimal Surface.
abstract: Bicontinuous cubic phases are of significant importance for numerous applications, for example, for the crystallization of membrane proteins, as photonic materials and as templates for porous silica. A new variant of bicontinuous cubic liquid crystalline phase with Ia3‾ d lattice is reported herein for X-shaped bolapolyphiles. It was shown that in this class of compounds, cubic-phase induction can be achieved by proper aromatic core fluorination; in addition, the first cubic phases having π-conjugated oligo(phenylene ethynylene) rods on the gyroid minimal surface were obtained. These new structures composed of 3D folded layers of parallel arranged π-conjugated rods should allow charge transport in all three dimensions, which is of interest for organic semiconductor applications.
