Diphosphonate Functionalization of a Polyoxometalate-Organic Cage Enhances Proton Conductivity

Diphosphonate functionalization of a cubic polyoxovanadate–organic cage resulted in enhanced proton conductivity of 1.90 × 10 −2 S cm −1 , compared to 3.38 × 10 −3 S cm −1 for an analogous monophosphonate-derived cage, at...
