We describe the synthesis and supramolecular properties of a bifurcated molecule decorated with two units of an in-house receptor for [60]fullerene, based on the electron donor exTTF, and a PC 61 BA derivative as recognizing units. This monomer self-assembles to form arborescent and dynamically polydisperse supramolecular aggregates, mainly through π−π interactions. This constitutes a fundamentally novel kind of organization of electroactive materials that lies at the interface between dendrimers and supramolecular polymers.
