Abstract Redox‐active p ‐type phenothiazine based organic cathodes have captured increasing attention for lithium‐organic batteries due to their high voltage output and rich chemical modification. However, capacities are generally limited one redox event per molecule; while the di‐cation states subject rapid decomposition cannot be effectively utilized. Herein, a scalable synthesis of phenothiazine‐based polymer ( MPT‐CC ) is reported, that can fully utilize two‐electron storage by raising its highest occupied molecular orbital (HOMO). Lithium‐organic using this as cathode displayed specific capacity 178 mAh g −1 at 0.2 A . This also displays excellent cycling stability. After 1000 cycles , stable 194 with ≈100% retention obtained. Even 2 after 10,000 cycles, 98 reversibly achieved. Its practical applicability has been successfully demonstrated in //graphite full cell, displaying good performance. work contributes major advancement design performance energy devices.

Charge transfer (CT) complexes formed by donor–acceptor (D-A) pairs play a critical role in organic optoelectronic devices, where the CT effect is highly correlated with molecular packing and intermolecular interaction. There are still challenges exploring mechanisms of charge noncrystal state. Most studies regulated altering π-conjugated backbone substituents, which would lead to some uncertainties packing-property relationship. Herein, we utilized triazatruxene (TAT) different alkyls as donors 1,3,5-benzenetricarbonitrile (TCNPh) derivatives acceptors. The systems complex were constructed simply grinding mixture study arrangement transfer, an obvious odd–even could be observed. Thus, our further enriched alkyl chain regulation, allowing for more profound understanding relationship among aggregation structures, interactions, characteristics complex.
