Amphoteric tellurium-containing π-donors'acceptors are reported. The electrical and magnetic properties of the charge-transfer complexes and radical cation salts prepared from 1 (see Figure; X [BOND] Te, R1 [BOND] Me) are presented. 1 exhibits a remarkably low oxidation potential compared with S analogues and a one-step two-electron reduction potential, indicating that its derivatives could also be of use as the first Te-containing organic electron acceptors.
