Abstract While metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) have been widely investigated as porous conductive materials, the research on the electrical properties of HOF materials has been limited. Moreover, the electrical conductivity of HOF materials is typically several orders of magnitude lower than that of MOFs and COFs. In this work, a HOF material based on naphthalene diimide is designed and achieved a remarkable electrical conductivity of 2.9 × 10 −2 S cm −1 after hydrazine doping, which represents the highest value reported in the HOF system to date. In addition, this material exhibits a reversible change of its electrical conductivity under exposure to ammonia which is promising for gas‐sensor applications. The demonstration reveals a new dimension of HOFs as conductive materials and opens up possibilities for new HOF‐based devices.
