the all-carbon network graphdiyne, are described. Assembly of these macrocycles is accomplished via 6-fold Sonogashira cross-coupling of hexaiodobenzene using Pd[P(o-Tol)(3)](2) and CuI as the catalytic system. The development of these modified Sonogashira conditions is detailed. This work has led to the synthesis of a newfamily of hexakis(phenylbutadiynyl)benzene derivatives (4a-c), the largest of
