Synthesis and Properties of Dendralenes with Redox-active 1,3-Dithiol-2-ylidenes and Dicyanomethylidene and Application to Rechargeable Batteries
Dendralenes possessing both strongly electron donating 1,3-dithiol-2-ylidenes and electron accepting dicyanomethylidene (2-4) have been successfully synthesized. The results of cyclic voltammetry suggest that they exhibit oxidation processes accompanied by a conformational change. The rechargeable batteries using the tetrathiafulvalene-fused derivatives (3d, 4) as a positive electrode material showed the initial full charge-discharge capacities of 150 and 189 mAhg(-1).
