A super water-stable europium-organic framework: guests inducing low-humidity proton conduction and sensing of metal ions

The ordered dimethylammonium cations [H2N(CH3)2](+) and helical water spirals as guest species make a super water stable europium-organic framework possess a proton conductivity of over 10(-3) S cm(-1) at 68% relative humidity. A fluorescent probe for Fe(3+) and Cu(2+) ions via a different mechanism...

Zusammenfassung:The ordered dimethylammonium cations [H2N(CH3)2](+) and helical water spirals as guest species make a super water stable europium-organic framework possess a proton conductivity of over 10(-3) S cm(-1) at 68% relative humidity. A fluorescent probe for Fe(3+) and Cu(2+) ions via a different mechanism has also been realized.
