functionalized compound arms, Suzuki couplings were applied. The crucial introduction of the pyridine C-2 and C-6substituents occurred by Fe(acac)3-catalyzed alkylations (acac = acetylacetonate). The preparation of the C3-symmetrical compound involved an alternating sequence of halogenations and coupling reactions. The self-assembly behavior of the four resulting star-shaped compounds at the interface
