Just like tinkertoys : An alternative approach to access imidazole‐containing π‐conjugated materials is presented. The imidazole core was assembled at the same time as the oligomer by the palladium‐catalyzed multicomponent coupling of imines, diimines, and di(acyl chloride)s, thus providing access to families of new conjugated materials, each formed in a one‐step, catalytic reaction (see scheme; Ts=4‐toluenesulfonyl).
