Graphical Abstract

Circularly polarized infrared irradiation of a hexagonal columnar mesophase with a free-electron laser causes the liquid crystal to change from an “edge-on” alignment to a uniformly homeotropic “face-on” alignment (see Figure) due to vibrational excitation of the aromatic C–H vibration band of triphenylene.
