High proton conduction in an excellent water-stable gadolinium metal–organic framework†
Abstract
A new metal–organic framework with excellent water stability, {H[(N(CH3)4)2][Gd3(NIPA)6]}·3H2O (1, H2NIPA = 5-nitroisophthalic acid), displays a proton conductivity of 7.17 × 10−2 S cm−1 (at 75 °C and 98% relative humidity), which is among the highest values for proton-conducting MOFs.
