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 CÀ PÀ C angles and phosphorusÀ 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
