Guest-tuned proton conductivity of a porphyrinylphosphonate-based hydrogen-bonded organic framework

A porous porphyrin-based hydrogen-bonded organic framework (HOF) was constructed, and its proton conductivity was improved through a two-step guest-tuned strategy. After regulation, the proton conductivity of the HOF reaches 1.59 × 10⁻¹ S cm⁻¹ at 80 °C and 99% RH.
