Thienyl directed polyaromatic C-C bond fusions: S-doped hexabenzocoronenes. | LitMetric

Thienyl directed polyaromatic C-C bond fusions: S-doped hexabenzocoronenes.

Chem Commun (Camb)

School of Chemistry, University of Dublin, Trinity College, Dublin 2, Ireland.

Published: March 2011

With a view to combining the desirable electronic and photochemical properties of hexabenzocoronene (HBC) and the C-C bond forming capabilities of thiophenes, 1-(3-thienyl)-2,3,4,5,6-penta(4-tert-butyl-phenyl)benzene (1) was oxidised using FeCl(3). The resulting products, superaromatic thiophene (2) and its 5,5'-dimer (3), are S-HBC systems and provide a new pair of spectral comparators.
