a–g, Nyquist plots of H3PO4@TPB-DMeTP-COF measured at different temperatures under anhydrous conditions. h Nyquist plot of H3PO4@TPB-DMeTP-COF after 20-h continuous run at 160 °C. i Temperature profiles of proton conductivities of H3PO4@TPB-DMeTP-COF (red circles and line), 75%H3PO4@TPB-DMeTP-COF (blue circles and line) and 50%H3PO4@TPB-DMeTP-COF (black circles and line). Circles are experimental data and lines are curve fitting.
