Electrically conductive metal-organic frameworks (EC-MOFs) have attracted growing interest with their potential uses in various applications such as electrochemical sensing, energy storage, and electrocatalysis. However, their electrical properties are often underestimated due to poor synthetic control, including unavoidable defects that hinder efficient charge transport. Herein, we demonstrate the defect healing on EC-MOFs, utilizing ligands as healing precursors. The results showed enhanced conductivity values up to 700 times higher when Cu₃(HAB)₂ was treated with hexaaminobenzene (HAB) ligands than the untreated counterpart. Our finding highlights that facile postsynthetic treatment can further improve conductivity of existing EC-MOFs.

通过缺陷修复提高半导体 MOF 的导电性

导电金属有机框架（EC-MOF）因其在电化学传感、能量存储和电催化等各种应用中的潜在用途而引起了越来越多的兴趣。然而，由于合成控制不佳，包括阻碍有效电荷传输的不可避免的缺陷，它们的电性能经常被低估。在这里，我们展示了 EC-MOF 上的缺陷愈合，利用配体作为愈合前体。结果表明，当用六氨基苯 (HAB) 配体处理Cu ₃ (HAB) ₂时，电导率值比未处理的对应物高 700 倍。我们的发现强调了简单的合成后处理可以进一步提高现有 EC-MOF 的电导率。
