High Charge Mobility in Discotic Liquid-Crystalline Triindoles: Just a Core Business?

The stacking order and distance in columnar phases of triindole‐based liquid crystals is controlled by an ethynyl linker (see picture; orange rod) between the central triindole core (green) and the peripheral flexible chains of a discotic mesogen. Hole (h) mobility is very high even if the stacking...

Summary:The stacking order and distance in columnar phases of triindole‐based liquid crystals is controlled by an ethynyl linker (see picture; orange rod) between the central triindole core (green) and the peripheral flexible chains of a discotic mesogen. Hole (h) mobility is very high even if the stacking distances is not very short and the conjugated system is not particularly extended.
