Microsegregation and a flat, radial conformation of the polar core region are responsible for the columnar mesophases formed by the non‐anisometric sixfold alkoxy‐substituted 2,4,6‐triarylamino‐1,3,5‐triazines ( 1 ). Charge‐transfer interactions with flat acceptor molecules such as 2,4,7‐trinitrofluoren‐9‐one impose a linear conformation of the triarylmelamines, which induces lamellar mesomorphic structures.
