Electrochemical Behaviors of Hexathiadipentalene Ring, Dithiol Ring, and Methyl Sulfide Groups on Anthracene Derivatives Confined on Electrode
Hexathiadipentalenoanthracene (hexathioanthracene) and related-structure compounds which are based on anthracene (ANT) containing redox-active organosulfur unit were synthesized, and their redox-activities of trithiapentalene ring, dithiol ring, and its methyl sulfide function groups linked on the ANT molecule were examined with the cyclic voltammetric method using their coated electrodes. The electrochemical oxidation processes for their neutral compounds (hexathiadipentalenoanthracene, 1,4,5,8-tetra (methylthio)anthracene and anthra-bis-[1,2]dithiole) are electrochemically reversible and exhibit stepwise two one-electron transfer redox responses in an ethylene carbonate (EC): diethylcarbonate (DEC) (1: 3 volume ratio) solution containing 1.0 M LiPF6 in the potential range from 3.00 to 4.60 V (versus Li/Li+).
