Two-dimensional (2D) membranes are emerging candidates for osmotic energy conversion but the trade-off between ion selectivity and conductivity remains the key bottleneck. Here, the authors demonstrate a fully crystalline imine-based 2D polymer membrane capable of combining excellent ionic conductivity and high selectivity for osmotic energy conversion.
