Within the crystal, the negatively charged TCNQ ions are arranged so that their central, flat, six-membered rings are piled up on top of each other in the long direction of the needle. The energy of a laser pulse excites electrons; part of this energy is transferr...

String of fullerene pearls

When the pincer-like receptor grasps the fullerene, its flat aromatic rings spread over the equally flat ring systems on the fullerene surface. This results in special binding interactions between the electrons of these ring s...
