Abstract
π-Conjugated molecules are the active materials in organic electronics, yet the range of available materials is limited by the nontrivial, multistep synthetic process required to obtain long π-conjugated backbones. Here, Diels–Alder cycloaddition and its reactivity and selectivity are evaluated as a means for obtaining long, novel, π-conjugated backbones. Particular attention is paid to the Diels–Alder conjugation products of furans, such as selectively substituted arenes and, potentially, carbon nanoribbons.
