The synthesis and characterization of novel S-shaped N-heterophenes is reported. The targets contain a central anthracene connected to two heterophenanthrene units. N-Heterophenes are synthesized by reacting Boldt's 1,2,6,7-anthracenetetraone with different dialkynylated ortho-diaminobenzenes. The condensation yields range from 63 to 75 %; all of the N-heterophenes are stable and isolable. S-Express: The efficient synthesis of four different S-shaped N-heterophenes by condensation of aromatic ortho-diamines with 1,2,6,7-anthracenetetraone is reported. The optical and electronic properties of the targets were evaluated and their properties are discussed through comparisons with computational studies.
