title: Non-classical heteroacenes: synthesis and properties of anthra[2,3-c:6,7-c']dithiophene derivatives.
abstract: A new class of linear heteroacenes, anthra[2,3-c:6,7-c']dithiophenes, containing non-classical (non-Kekulé) thiophene in a 22-electron π-conjugated system have been prepared by electrochemical reduction. The electronic properties have been studied by DFT calculations and spectroelectrochemistry, supporting the formation of a triplet electronic structure.
