Diphosphonate Functionalization of a Polyoxometalate-Organic Cage Enhances Proton Conductivity
Abstract
Diphosphonate functionalization of a cubic polyoxovanadate–organic cage resulted in enhanced proton conductivity of 1.90 × 10−2S cm−1, compared to 3.38 × 10−3 S cm−1 for an analogous monophosphonate-derived cage, at 373 K and 98% relative humidity.
