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.
Wang et al. (2014) studied this question.
