Humidity-Induced Self-Oscillating and Self-Healing Hypercrosslinked Metal-Organic Polyhedra Membranes. [PDF]

Adv Sci (Weinh)
A new type of hypercrosslinked metal–organic polyhedra (HCMOP) membrane is generated by covalent crosslinking of boronic acid‐modified Zr‐based MOPs with polyvinyl alcohol. Due to the dynamic borate networks, HCMOPs can realize humidity‐induced self‐oscillating and self‐healing properties.
