“…It was found that the DA complexes of the benzenoid hydrocarbons with TCNQ molecules exhibit semiconducting properties characterized by a relatively narrow band gap and moderate charge transfer between the counterions. [62] The DA complexes of TCNQ with the PAH 1, [63] 2, [64] 3, [65] 4, [66] 5, [67] 6, [68] 7, [69] 8 [62] have been reported earlier. It has been commonly observed that most acenes crystallize in a 1 : 1 ratio with TCNQ.…”

In this review article, the synthesis, characterization and physico‐chemical properties of the organic donor‐acceptor complexes are highlighted and a special emphasis has been placed on developing them as semiconducting materials. The electron‐rich molecules, i.e., donors have been broadly grouped in three categories, namely polycyclic aromatic hydrocarbons, nitrogen heterocycles and sulphur containing aromatic donors. The reactions of these classes of the donors with the acceptors, namely tetracyanoquinodimethane (TCNQ), tetracyanoethylene (TCNE), tetracyanobenzene (TCNB), benzoquinone, pyromellitic dianhydride and pyromellitic diimides, fullerenes, phenazine, benzothiadiazole, naphthalimide, DMAD, maleic anhydride, viologens and naphthalene diimide are described. The potential applications of the resulting DA complexes for physico‐electronic purposes are also included. The theoretical investigation of many of these products with a view to rationalise their observed physico‐chemical properties is also discussed.

“…Zeybek and co-workers transformed the carbazole (Cz) unit into its dimeric (67), trimeric (68) and polymeric (69) forms and examined the formation of CT complexes of these Cz donors with TCNE. [136] (Figure 16) The resulting complexes exhibited a weak association and appeared as dark blue compounds.…”
