Well stacked : A liquid‐crystalline material with crystalline π stacks has been synthesized in which the room‐temperature liquid‐crystalline phase consists of alternating 2D‐crystalline mesogen layers and liquidlike alkyl layers. A long‐range ordered layer structure forms as a consequence of the resulting microsegregation (see picture), with the π stacks contributing to the 2D crystalline order that exists within a layer.
