A series of pyrene-fused azaacenes with four and six linearly fused rings that possess LUMO levels between-3.7 and-4.3 eV is reported. These LUMO values are remarkably lower than those typically observed for pyrene-fused azaacenes, even for systems with sixteen linearly fused rings, and are comparable to those observed for state-of-the-art n-azaacenes.
