This paper reports the synthesis and characterization of the first megadalton polyaromatic dendrimer (and earlier generation dendrimers). They got beautiful, albeit broad, MALDI spectra, narrow GPC traces (remarkably, even for late-generation species), and TEM images of these gigantic molecules. The synthesis was achieved via D.A. chemistry/deprotection of alkynes.
