Abstract

(E,E,E)‐2,4,6‐Tris(styryl)pyridines 2a‐c with 3, 6 or 9 dodecyloxy substituents were prepared by the highly stereoselective condensation reaction of collidine (8) and the corresponding phenyl‐(1‐phenyl‐methylidene)amines 7a‐c (Siegrist reaction). In contrast to the corresponding compounds with a benzene or a 1,3,5‐triazine core, 2a‐c do not show any hints for the formation of thermotropic liquid crystals. The major application of such star‐shaped systems is in the field of nonlinear optics.
