Wires to particles : A subtle balance of H‐bonding, π‐stacking, and van der Waals interactions facilitates the concentration‐controlled self‐assembly of a short molecular wire (see figure) into nanoparticles and fluorescent microspheres in nonpolar hydrocarbon solvents. Above a critical concentration, a blue‐light emitting organogel is formed.
