Only five generations of growth are necessary to generate the phenylacetylene dendrimer 1 , the largest pure hydrocarbon (C 1398 H 1278 ) and one of the largest dendrimers (diameter: 12.5 nm). Architectures prepared by the innovative scheme described in this communication quickly acquire a large size due to the unique pattern of nonlinear growth. In the picture, the circles symbolize benzene rings, the lines CC bridges, and the branched groups on the periphery tBu substituents.
