摘要

有機材料有望成為下一代電極材料，因為它們的成本相較於其他重金屬製成的電極材料來的低、具回收性、可客製化以及材料對環境友善。本論文經由三甲酰基間苯三酚（TFP）和萘二酰亞胺二胺（NDI）的縮合反應，合成了NDI-TFP高分子。這種具有氧化還原性質的高分子聚合物其共軛系統提供了電子傳遞途徑，其中萘二酰亞胺單元可以經過兩個單電子還原過程產生陰離子和二陰離子的自由基。透過固態循環伏安法證明了NDI-TFP高分子聚合物此材料具有氧化還原活性，並研究其在鈉離子電池電極材料中的應用。

Organic materials are promising candidates as next-generation electrode materials because they are potentially low-cost, recyclable, tunable, and environmentally friendly compared to conventional inorganic electrodes. Through the condensation of triformylphloroglucinol (TFP) and naphthalene-diimide diamine (NDI), TFP-NDI porous organic polymer was synthesized. The open channels of redox-active TFP-NDI polymer provide pathways for metal ions and the naphthalene-diimide units can undergo two one-electron reduction processes to yield radical anion and dianion. The redox activity of TFP-NDI was revealed by solid-state cyclic voltammetry and its application as electrode material for sodium-ion batteries was studied.
