The electrical conductivity of network polytetraphenylcalix [resorcinarene (I) and sulfonated polytetraphenylcalix [resorcinarene (II) in the form of Н+, Na+ , Li+, Ag+, Ba2+, Ni2+, Cu2+, and Zn2+ cations was measured. It was found that the specific conductivity of the polymers in the form of doubly-charged metal cations was 0.2-0.4 S/m. It increased to 1-1.5 S/m when the polymer was in the form of singly-charged metal cations. The specific conductivity of the H-form polymer II became as high as 20 S/m. The self-diffusion coefficients and activation energies of metal cation diffusion in the polymer phase were calculated over the temperature range 298333 K.
