摘要：

(Chemical Equation Presented) Wires to particles: A subtle balance of H-bonding, π-stacking, and van derWaals 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. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
