Starting from aromaticortho-dialdehydes, we devised a homo-elongation protocol that combines a Wittig olefination and subsequent intramolecular Knoevenagel condensation to produce acene diesters and dinitriles.

Polyaromatic hydrocarbons are central molecules in the future of nanotechnology. However, the synthesis of these molecules is limited by their lack of solubility in solvents, especially green solvents, their ease of oxidation in solution and use of harmful reagents. Solvent-free mechanochemistry has been shown to have excellent potential for these types of molecules and should provide a much more environmentally

on template-assisted multiple benzannulation emerges. This efficient and versatile approach enables the synthesis of terminal-ring-substituted pentacene and tetracene derivatives with considerable structure diversity. With this protocol, the authors also revealed an amphiphilic pentacenederivative that self-assembles to form helical nanowires.
