Abstract

Abstract: Two water stable phosphate‐amidinium charge‐assisted hydrogen‐bonded organic frameworks (HOFs), HOF‐FJU‐12 ([DPBA⋅PAM]0.5 ⋅ 0.2DMF⋅H2 O) and HOF‐FJU‐13 ([DPBA ⋅ 1.5PAM] ⋅ 1.5DMF⋅H2 O) (DPBA=3, 5‐diphosphonobenzoic acid, PAM=terephtalimidamide, DMF= N, N ‐Dimethylformamide) have been synthesized and structurally characterized. Single‐crystal X‐ray diffraction shows that HOF‐FJU‐13 is a layered structure with continuous hydrogen‐bonding networks along a axis, which plays an important role in proton conduction. The highest proton conductivity of HOF‐FJU‐13 (1.14×10 −4 S/cm) is about 7.4 times higher than that of HOF‐FJU‐12 (1.54×10 −5 S/cm) under the conditions of 60 °C and 98 % relative humidity. Abstract :
