Inside Cover: Completely Encapsulated Oligothiophenes: Synthesis, Properties, and Single-Molecule Conductance (Angew. Chem. Int. Ed. 50/2011)
Encapsulated π-conjugated systems are central building blocks in single-molecular devices. In their Communication on page 11980 ff., Y. Aso, H. Tada et al. report a series of oligothiophenes having homogeneously substituted encapsulating units that maintain the efficient conjugation of the π systems. Owing to the absence of intermolecular interactions between π-conjugated backbones, the electrical conductance of the single molecule determines the real decay constant of the oligothiophenes.
