Dibenzothiophenesulfone undergoes a two‐electron reduction in a single step at a very negative potential of −1.8 V (versus Ag/AgCl) in organic electrolytes, due to the electron‐withdrawing sulfone group and the stability of the resulting dianion. The heterogeneous electron‐transfer rate constant for the reduction is approximately 10⁻¹ cm s⁻¹, which is significantly faster than most redox‐active species. The results presented herein suggest that dibenzothiophenesulfone is a potential candidate for use as an anode‐active material with high‐energy density. In addition, radical polymerization of vinyldibenzothiophenesulfone yielded poly(vinyldibenzothiophenesulfone) with a high molecular weight. A rechargeable device is fabricated with only organic compounds; poly(vinyldibenzothiophenesulfone) as the anode, 2,2,6,6‐tetramethylpiperidine‐1‐oxyl (TEMPO)‐substituted poly(methacrylate) as the cathode, and tetraethylammonium salt and organic solvent as the electrolyte. This device yields a maximum output voltage of 2.6 V in these organic devices, and the active component of the anode displays a very high‐energy density of >500 mWh g⁻¹.

聚（乙烯基二苯并噻吩砜）：在极负电势下对具有高能量密度的全有机可充电设备的氧化还原能力

由于吸电子砜基团和生成的二价阴离子的稳定性，在有机电解质中，二苯并噻吩砜在－1.8 V（相对于Ag / AgCl）的极负电势下一步经历了两个电子的还原。还原的异质电子传输速率常数约为10 ^-1  cm s ^-1，这比大多数具有氧化还原活性的物种要快得多。本文给出的结果表明，二苯并噻吩砜是用作具有高能量密度的负极活性材料的潜在候选者。另外，乙烯基二苯并噻吩砜的自由基聚合产生具有高分子量的聚（乙烯基二苯并噻吩砜）。仅使用有机化合物制造可充电设备；阳极为聚（乙烯基二苯并噻吩砜），阴极为2,2,6,6-四甲基哌啶-1-氧基（TEMPO）取代的聚（甲基丙烯酸酯），电解质为四乙铵盐和有机溶剂。该设备在这些有机设备中产生的最大输出电压为2.6 V，阳极的活性成分显示出非常高的能量密度，> 500 mWh g ^-1。
