5,6:11,12-Bis(ditelluro)tetracene: Synthesis, Molecular, and Supramolecular Properties

Abstract

5,6:11,12-Bis(ditelluro)tetracene (5,6,11,12-tetratellurotetracene, TTeT), synthesized in 13% yield from 5,6,11,12-tetrachlorotetracene and a new sodium ditelluride reagent, absorbs at longer wavelengths in both solution and solid state and is oxidized electrochemically at a lower potential, compared to its selenium analogue. The structure of TTeT, a monoclinic crystal (a = 11.746 (4) Å, b = 4.364 (2) Å, c = 15.831 (5) Å, β = 90.57∘, space group P21/n, R = 0.030, Rw = 0.037), exhibits short interstack contacts of 3.701 (1) Å. © 1982, American Chemical Society.
