Abstract

Large polycyclic organic π systems of high symmetry, such as acenes,[1] rylenes,[2] and fullerenes,[3] are not only exciting objects of synthesis and of great fundamental interest, but are also gaining more and more importance as electronically and optically active components in devices such as field-ffect transistors [4] and solar cells.[5] In 1948, Clar reported the synthesis of the orange compound 1, which he called ovalene, which he ...
