与无机物相比,有机化合物因其环境友好、来源广泛的优势而成为潜在的电极候选者。然而,开发具有高性能和绿色可持续性的有机电极材料仍然是一项重要挑战。六氮杂苯并苯(HAT)衍生物作为有机电极显示出良好的应用前景。本文制备并研究了苯并[i]苯并[6,7]喹喔啉[2,3-a]苯并[6,7]喹喔啉[2,3-c]吩嗪(BBQP)作为水系锌-离子电池 (AZIB) 和锂离子电池 (LIB) 的阳极。得益于大的扩展 π-共轭芳族结构、不溶性和高电容贡献 BBQP 电极表现出出色的倍率性能(66.6 mA hg -1 at 10 A g -1) 和 AZIB 中优异的长循环寿命(112.5 mA hg -1在 1 A g -1下超过 2000 次循环)。此外,各种异位表征(FT-IR、Raman、XPS和SEM-EDS映射)证实BBQP电极的C=N键是Zn 2+储存过程中的活性中心。此外,Li//BBQP 电

Hexaazatrianthracene (HATA) and hexaazatriphenylene-hexacarbonitrile HAT(CN)6} ligands form coordination complexes with high-spin (S=2) FeII atoms in dianion and radical-trianion states. This provides weakantiferromagneticexchange or ferromagneticalignment of the FeII spins within the coordination assemblies.
