Tetrathiafulvalene. XVIII. Elektronen-Donator-Akzeptor-Komplexe von Tetrathiafulvalenen (TTF) mit Tetracyanochinodimethan (TCNQ)

Tetrathiafulvalenes. XVIII. Charge-Transfer-Complexes of Tetrathiafulvalenes (TTF) with Tetracyanoquinodimethane (TCNQ) TTF form CT-complexes with TCNQ in solvents having small E_T-values, whose association constants are estimated. The energy of the absorption maximum of the CT-complex between octamethylentetrathiafulvalene and TCNQ increases linearly with decreasing E_T-values of the solvents. In chloroform the energy of the absorption maximum of the CT-complexes between TCNQ and tetrathiafulvalenes increases linearly with the oxidation potential of the tetrathiafulvalene.
