Abstract

It is found that the principal axes of the g‐tensor of the three complex TCNQ salts Qn(TCNQ)2, NPQn(TCNQ)2, and TEA(TCNQ)2 correspond to the geometry of the TCNQ molecules, known from crystal structure analysis, and the corresponding diagonal g‐values, calculated for B TCNQ molecule, are the same within an accuracy of 5 × 10−5. This points to the fact that the ESR signal in these materials arises from electrons of the TCNQ molecules, that is–as all three donors have closed shells after ionization–the donor‐acceptor charge transfer is complete. At the same time the measurements give evidence that the g‐tensor in these salts is unaffected by the intrachain delocalization, which is different for these materials.
