摘要： Disclosed are viologen derivatives as an electrochromic material having improved stability and lifetime, a metal oxide electrode including the same, and an electrochromic device using the viologen derivative as an electrochromic material. The viologen derivative includes a suitable regulator group capable of increasing ΔE that is a potential difference between E1 (potential at the first redox reaction) and E2 (potential at the second redox reaction). When ΔE increases, the mole fraction of viologen molecules present in the second reduction state decreases. Therefore, it is possible to lower the mole fraction of viologen molecules present in an irreversibly reduced state at an applied potential, thereby increasing the lifetime of an electrochromic material and an electrochromic device.

摘要翻译： 公开了作为具有改善的稳定性和寿命的电致变色材料的紫罗兰衍生物，包含该化合物的金属氧化物电极以及使用紫精衍生物作为电致变色材料的电致变色装置。 紫精衍生物包括能够增加作为E1（第一氧化还原反应的电位）与E2（第二氧化还原反应的电位）之间的电位差的DeltaE的合适的调节剂组。 当DeltaE增加时，存在于第二还原状态的紫精分子的摩尔分数降低。 因此，可以降低在施加电位下以不可逆还原状态存在的紫色分子的摩尔分数，从而增加电致变色材料和电致变色装置的寿命。
