Tetraarylanthracenes containing several fluoro groups were synthesized using the ruthenium-catalyzed C–O or C–F arylation with arylboronates and their structural and spectroscopic studies were conducted. The RuH2(CO)(PPh3)3-catalyzed C–O arylation of aromatic ketones was found to be effective for the introduction of aryl groups containing multiple fluoro groups. Anthracenes possessing fluorinated aryl

The molecular design and construction of a minimalisticnanocar is described, featuring an anthracene chassis and four benzene derivatives as wheels. After sublimation and adsorption on an Au(111) surface, controlled and fast manipulation of a nanocar is shown along the surface using the tip of a scanning tunneling microscope.
