Abstract

Herein, we report two charge-assisted hydrogen-bonded organic frameworks (iHOF-24 and iHOF-25) with 3D/2D hydrogen-bonding networks, which exhibit high ionic conductivity for alkali metal ions. Among them, the conductivity of Li+ is higher than that of Na+ and K+, and the ionic conductivities of Li@iHOF-24 and Li@iHOF-25 at 30 °C were 9.44 × 10−5 and 9.85 × 10−5 S cm−1. This change is attributed to the distance between neighboring carbonyl groups in iHOF-24 and iHOF-25, as well as the radius of the loaded alkali metal ions.
