There has been growing research interest in hydrogen bonded organic frameworks (HOFs) by virtue of their great structural crystallinity, large surface areas and porosity. Their potential in electrochem. applications, unfortunately, remains elusive because weak hydrogen bonds would dissociate in solution that eventually compromises the structural integrity. Herein, it is demonstrated that this issue may be overcome by designing and introducing multisite hydrogen bonding within HOFs. 2D mol. sheets are prepared using diaminotriazole as the linkers for the first time. In spite of the mol. thickness (≈1 nm), they are chem. stable and mech. robust, and have diminished solubility in most polar or nonpolar organic solvents. This solution-stable HOF exhibits an excellent electrochem. performance for Na+ ion storage. In particular, it enables an exceptional cycle life of >10 000 cycles at 1 A g-1, which is far superior to most other organic electrode materials. Theor. simulations indicate that the activation barrier for the intralayer or interlayer diffusion of Na+ ions within the organic frameworks is small.
