“…The authors attribute this to the greater ease of shedding solvent molecules for a softer ion such as K + , while Li + has significant solvation even in the absence of a crown ether when entering some of the polymer matrices, depending on the microstructure of the electrode. GCD using ion-conducting polymer-based electrolytes such as poly(ethylene oxide) (PEO) has also been investigated as means to suppress dendrite formation and increase battery lifetimes. ,− Alternatively, Troshin and co-workers used polymer electrolytes to hinder the molecular dynamics of electrode materials, thereby improving their cyclability. They supplemented these results with computational studies to support that the mobility of the electrode polymer strands hindered deintercalation, and thus oxidation, during recharging.…”

Electroactive materials are central to myriad applications, including energy storage, sensing, and catalysis. Compared to traditional inorganic electrode materials, redox-active organic materials such as porous organic polymers (POPs) and covalent organic frameworks (COFs) are emerging as promising alternatives due to their structural tunability, flexibility, sustainability, and compatibility with a range of electrolytes. Herein, we discuss the challenges and opportunities available for the use of redox-active organic materials in organoelectrochemistry, an emerging area in fine chemical synthesis. In particular, we highlight the utility of organic electrode materials in photoredox catalysis, electrochemical energy storage, and electrocatalysis and point to new directions needed to unlock their potential utility for organic synthesis. This Perspective aims to bring together the organic, electrochemistry, and polymer communities to design new heterogeneous electrocatalysts for the sustainable synthesis of complex molecules.

“…39,242 To this end, Zhang et al found that increasing the relative molecular mass is an effective way to reduce the solubility. 243 They designed the PTMA incorporated with anthraquinone (AQ), which increases the M n to 405 kg mol −1 and alleviated the capacity loss to a certain extent. AQ functionalized PTMA with a core-sheath nanostructure contributes to wrapping the CNTs surface uniformly (Fig.…”

“…This idea could be transferred to a polymer system by incorporating AQ moieties into a typical radical polymer PTMA. Indeed, the aromatic AQ could also facilitate polymer dispersion at the surface of MWCNTs through noncovalent π−π interaction, 35 creating an ideal construct for the AQ-catalyzed TEMPO reduction (Scheme 1c).…”

“…Recently, we functionalized PTMA with pendant AQ groups, i.e., P(TMAco-AQ). 35 The AQ moieties act as redox mediators and help form polymer-wrapped MWCNT composite via noncovalent π−π interaction between aromatic AQ and MWCNT (Figure 3a). As previously reported, the resulting molecular-level P(TMA-co-AQ) dispersion could facilitate charge transfer and ion transport.…”

Tetramethylpiperidine-1-oxyl (TEMPO) functional polymers are a type of organic electroactive material featuring a two-electron redox process. However, the electrochemical reduction of TEMPO (TEMPO •/− ) is rarely adopted for energy storage due to its slow reaction kinetics. Here, we report using anthraquinone (AQ) as an organic redox mediator to promote TEMPO reduction kinetics. The catalytic effect of AQ is verified by electrochemical in situ FTIR spectroscopy in a model three-electrode system and further evidenced by cyclic voltammetry and chronoamperometry, providing a turnover frequency of 69 h −1 . To exemplify the AQ catalytic effect in energy storage performance, we incorporate AQ groups into a typical TEMPO polymer (i.e., poly(TEMPO-methacrylate), PTMA). The AQ-catalyzed TEMPO reduction and AQ/carbon π−π interaction synergistically reduce the heterogeneous charge transfer resistance and accelerate the kinetics of the TEMPO •/− process in the PTMA electrode. The half-cell tests of the AQ functional PTMA show two prominent discharge plateaus with an initial capacity of 174 mAh g −1 and a 0.18% capacity loss per cycle. Moreover, the discharge capacity based on the TEMPO •/− couple is about 85 mAh g −1 , 30% higher than that of the pristine PTMA. This new strategy could be widely applied to various organic redox systems to enhance their electrochemical kinetics and particularly improve the energy storage performance of organic polymer redox materials.
