We report the cyclic single-crystal-to-single-crystal transformation of three hydrogen-bonded organic frameworks (HOFs), induced by the change of temperature and humidity, which clearly reveals that the –SO₃⁻and –NH₂ groups in UPC-H7 and UPC-H8 facilitate the diffusion of water molecules into their anhydrous structures to form hydrous UPC-H9. Their proton conductivity was studied under different humidity at varying temperature, showing that the proton conductivity is closely related to water molecules entering the crystal structures arising from the hydrogen bonded reorganization in combination with the triaxial single-crystal proton conductivity tests.

三种氢键有机骨架的单晶至单晶转变和质子传导性

我们报告了由温度和湿度变化引起的三个氢键有机骨架（HOF）的循环单晶至单晶转变，这清楚地揭示了UPC中的–SO ₃⁻和–NH ₂基团-H7和UPC-H8促进水分子扩散到其无水结构中，从而形成含水的UPC-H9。在不同湿度，不同温度下研究了它们的质子电导率，表明与三轴单晶质子电导率测试相结合，质子电导率与水分子进入氢键重组产生的晶体结构密切相关。
