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

Chem Commun (Camb). 2021 Jul 1;57(53):6526-6529. doi: 10.1039/d1cc02556b.

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.
