Abstract Bis‐ and tetrakis(diphenylphosphino)tetrathiafulvalenes extended with an anthraquinoid spacer were successfully synthesized. X‐ray structure analysis revealed that the phosphorus atoms adopt the typical distorted tetrahedral geometry. Their average C−P−C angles and phosphorus−carbon distances resemble those of diphenylphosphino‐substituted TTF derivatives. The cyclic voltammograms consisted of one pair of irreversible, simultaneous two‐electron transfer waves. A combination of cyclic voltammetry experiments and DFT calculations suggested the coexistence of two different reduction processes depending on the scan rate.
