A novel family of conjugated dendrimers is used as model compounds to explore the effect of intermolecular interactions on photo‐physical and transport properties. The Figure shows the third generation of the dendrimers. The dendrimer generation controls the degree of chromophore interaction, which leads to a unique correlation between the chemical structure of the molecules and the macroscopic device properties (see also inside front cover).
