Emergence of uniform tilt and π-stacking in triangular liquid crystalline honeycombs

Abstract

The synclinic tilted organization of specifically designed polyphilic oligo(p-phenylene ethynylene) rods in cylindrical shells around triangular prismatic cells on the <5 nm scale leads to a new kind of liquid crystalline honeycomb composed of helical shells with alternating helix sense. Core fluorination at the outer ring modifies the core–core interactions, thus resulting in triangular arrays with face-to-face π-stacking along the honeycomb.
