Abstract

Model substances for oligomeric systems based on the incorporation of [2.2.2]paracyclophane into the repeating unit are linear polyenes bearing a paracyclophanyl residue in the terminal positions. The preparation of the polyenes 2a–c is described. In addition to the characterisation as diarylpolyenes, consideration of model compounds revealed that the [2.2.2]paracyclophanyl residues interact with pendent substituents according to a magnetic anisotropic mechanism.
