The frontispiece illustrates the single fluorophore‐bis(micrometer‐sized dsDNA) supramolecule. It shows a wide‐field single‐molecule fluorescence image of the fluorophores in the triblock architectures. The fluorescence appears as white spots, to which, in an artistic view, double‐stranded DNA molecules are attached. The triblock supramolecule is synthesized from a tetracarboxylic perylene derivative‐bis(oligodeoxynucleotide) by DNA hybridization/ligation and directly imaged by combined scanning force and single‐molecule fluorescence microscopy. The synthesis of this type of supramolecule is an important step towards single‐molecule electronic devices with reliable contacts after metallization of the DNA strands.
