In order to continuously develop devices with good applicability and the recent emergence of functional integration hybrid frameworks, there is an urgent need to convert metal organic framework (MOF) particles into thin films. Although some flexible polymers and unique modification methods have been proposed, no additive free and widely applicable strategies have been reported, hindering in-depth research on the relationship between structure and performance. A universal strategy for in-situ growth of large-area continuous MOF films with controllable microstructures has been proposed, which modifies multi-scale and multi structured substrates with poly (4-vinylpyridine) as anchor points and captures metal ion attraction through Coulomb trapping. Based on a clear structure adsorption separation mechanism, customized devices manufactured through in-situ growth can achieve highly selective adsorption and excellent synergistic separation of various industrial isomers. In addition, this strategy is also feasible for constructing MOF on MOF with different lattice parameters. This strategy is easy to implement and can be widely applied to the surface growth of various MOFs on the required substrate, providing a new concept for the development of hybrid MOFs with integrated customized functions.
