“…The heteroatom (S) containing polymer, polythianthrene, also acts as a p-type organic cathode to lose four outer-shell electrons at high reaction potentials and provide a high theoretical capacity of 388 mAh g −1 . 36 To enable this anion insertion reaction, two or more thioether groups should be connected with a conjugated structure, such as a benzene ring. During the anion insertion process, intramolecular electron transfer is triggered in the conjugated structure, and each sulfur atom loses an electron and possesses a positive charge.…”

Organic and polymer materials have been extensively investigated as electrode materials for rechargeable batteries because of the low cost, abundance, environmental benignity, and high sustainability. To date, organic electrode materials have been applied in a large variety of energy storage devices, including nonaqueous Li-ion, Na-ion, K-ion, dual-ion, multivalent-metal, aqueous, all-solid-state, and redox flow batteries, because of the universal properties of organic electrode materials. Moreover, some organic materials enable the batteries to be operated in the extreme conditions, such as a wide temperature range (−70 to 150 °C), a wide pH range, and in the presence of O2. As a guidance for the research in organic batteries, this Review focuses on the reaction mechanisms and applications of organic electrode materials. Six categories of reaction mechanisms and the applications of organic and polymer materials in various rechargeable batteries are discussed to provide an overview of the state-of-the-art organic batteries.

“…Intramolecular Friedel-Crafts electrophilic substitution represents perhaps one of the most common ladderization strategies, broadly used in the construction of ladder-type p-phenylenes and subsequently expanded to other frameworks. [24][25][26][27] A pendant group is usually required to serve as the electrophile and is typically activated in acidic conditions. Electron-rich aromatic units which can function as nucleophiles are required to facilitate the reaction.…”

Conjugated ladder-type oligomers are a class of important functional organic materials. They possess intriguing properties stemming from their fully fused aromatic backbones. The construction of the ladder-type backbone relies on a ‘ladderization’ step, which may be accomplished through either kinetically or thermodynamically controlled annulation reactions. The attributes of these reactions are discussed, with relevant recent examples. The development of these reactions is key to continued advances and innovation in the field of organic conjugated materials.1 Introduction2 Kinetic Annulations3 Thermodynamic Annulations4 Future Outlooks and Conclusion

“…32 Theoretically, thianthrene can be electrochemically oxidized to a double cation in two steps, with an onset potential of 0.74 V vs. Fc/Fc + , corresponding to 3.9 V vs. Li/Li + for the first oxidation. [33][34][35] Although the chemical and electrochemical properties of thianthrene-based materials have been investigated as cathodes, [36][37][38][39][40][41] they mainly include soluble small molecules or polymers which are insoluble but require complex synthesis (limiting the potentially large-scale applications with low cost).…”
