the cone-shaped cyclotriveratrylene (CTV). In this article, we report on the synthesis of CTV-I3 derivatives 3a and 3b and their Sonogashira cross-coupling with various terminal aryl-alkynes, to synthesize CTV-phenylacetylene derivatives in moderate to good yields. In this way, three star-like conjugateddendrimers with rigid macrocyclic cores 4k–m, which showed good photophysical properties, were
