Figure 2: Proton conductivity and electrochemical data for porous organic cage materials.
From: Three-dimensional protonic conductivity in porous organic cage solids

(a) Proton conductivities for salts 1 and 2, and for neutral CC3 at 303 K as a function of relative humidity. (b) Arrhenius plots showing the activation energies of the cage materials tested at 95% RH between 303–353 K. (c) Nyquist plots showing the impedance of CC3 at 303 K with varying relative humidity (RH) between 1 MHz–24.5 Hz.
