Metal‐Half‐Salen Chemistry for One‐Pot Mineralization on Hydrophobic Polymer Membranes
Here we report a versatile one‐pot synthetic strategy for organic–inorganic composite membranes, which leverages a metal half‐Salen system to precisely govern the competing kinetics of coordination and hydrolysis. In contrast to conventional two‐step metal‐phenol chemistries, our integrated approach substantially simplifies the fabrication process ...
