Besides the many aesthetic aspects of chemistry,[1] such as molecular complexity,[2] self-organization, and nonlinear dynamics, the sheer beauty and elegance of molecular structures has always played an important role in the development of chemistry.[3] A classic example is buckminsterfullerene, a molecule whose name is dedicated to a great architect. Starting from the idea of an elegant highly symmetrical C60 structure and its theoretical analysis, fullerene chemistry now lies in the mainstream of contemporary science.[4] The rapid growth of modern nanoscience and materials science has stemmed to an extent from the discovery of fullerenes.[5] Herein, we describe the investigation of a first representative of the new class of highly symmetric molecules with unusual electronic properties, namely the octathio [8] circulene (1)—the first fully heterocyclic circulene.[6] This molecule, which we have named “sulflower”(from sulfur and flower) has several remarkable features: It is both organic and inorganic as it has a belt of eight annulated thiophenic cycles and contains no hydrogen atoms. Its molecular formula C16S8 (or simply (C2S) 8) allows one to classify it as a novel form of carbon sulfide. Its highly symmetric planar structure resembles the bloom of a sunflower or an eight-pointed star (Figure 1). Several binary carbon–sulfur compounds are known besides CS2 and its polymeric form, such as C3S2, C3S8, C4S6, C5S7, C6S8, C6S10, C6S12, C8S8, and C9S9.[7] The hypothetical polymer (ÀC= CÀSÀ) n is also an isomeric form of C2S and some lower representatives of this have been synthesized.[8] Annulated oligothiophenes represent another form of carbon sulfide with the formula (C2S) n. There are two types of thiophenic ring annulation, namely 2, 3-b and 3, 2-b, that allow the formation of oligomeric annulated structures. Combination of these annulation types gives essentially an infinite
