1,3,4,6,7,9-Hexamethylbenzo[1,2-c:3,4-c′:5,6-c″]trithiophene (C-Me) was prepared by palladium-catalyzed methylations of the corresponding hexabromide C-Br. The twisted structure of C-Me has been confirmed by X-ray crystal analysis. The physical properties

Buckybowls are fascinating components of supramolecular assemblies owing to their unique bowl-shaped π-surfaces. Herein we present a protocol for the functionalization of a sulfur-doped buckybowl, trithiasumanene, via a brominated intermediate, from which thiolated trithiasumanenes were derived. The curved surface and electron-donating properties of thiolated trithiasumanenes promote their ready assembly with fullerenes to form concave–convex complexes. The supramolecular assembly behavior in solution was investigated by NMR analysis. The structures of supramolecular complexes were unambiguously characterized by crystallography. The crystals of the concave–convex complexes showed high thermal stability and photoconductivity.

(Figure Presented) Planar, but non-aromatic: The title [6]radialenes, which contain thiophene and selenophene units (see the ORTEP diagrams), can be prepared in a straightforward manner. X-ray crystal structures and the results of theoretical studies show that the central six-membered ring of these compounds, although planar and composed entirely of sp2-hybridized carbon atoms, is completely non-aromatic.
Cyclobutarenes. Part 3. Synthesis of Bromodicyclobutarenes and Some New Derivatives of the Benzocyclobutabiphenylenes

Sodium iodide debromination of tetrakis- and hexakis-(dibromomethyl)carbocycles gives bromodicyclobutarenes and/or quinodimethanes, and o-bis(dibromomethyl)biphenylenes give cyclobutabiphenylene derivatives.Dehydrohalogenation od these compounds generates
