Аннотация:A novel metal-organic framework IPCE-2Ni with outstanding proton conductivity (1.0×10-2S∙cm-1 at 75°C and 95%relative humidity) was obtained. The high concentration of free phosphonate groups and compensating dimetlylammonium cations bound by hydrogen bonds in the unique crystal structure of IPCE-2Ni is a key factor responsible for the observed high proton conductivity that is one order higher that for corresponding MOF based on 5,10,15,20-tetrakis(4-(phosphonatophenyl)- porphyrinato(2-))]nickel(II) IPCE-1Ni and comparable with leaders among MOFs.
