Abstract
Metal–organic frameworks (MOFs) have attracted considerable interest as functional porous materials for sensing, catalysis, separation, and interfacial engineering. However, their direct integration onto solid substrates remains challenging because surface nucleation and growth are difficult to control, often resulting in poor uniformity, weak adhesion, and limited compatibility with device-oriented platforms. Therefore, a simple interfacial strategy capable of guiding MOF formation on diverse substrates is highly desirable.
Herein, we present an initiated chemical vapor deposition (iCVD)-derived imidazole copolymer interface for surface-directed MOF growth. A p(VI-co-V3D3) layer was deposited as a conformal functional scaffold, where vinylimidazole units provide metal-coordination sites and the crosslinked V3D3 component supports a stable, substrate-compatible polymer interface. As a representative system, sequential exposure to cobalt ions and 2-methylimidazole induced the formation of cobalt–imidazolate framework structures directly on the iCVD-coated surface. The resulting polymer–MOF hybrid surface exhibited clear changes in surface chemistry, morphology, and crystallinity, supporting successful metal coordination and framework formation at the polymer interface. Although demonstrated here for a cobalt–imidazolate system, the coordination-based design of the imidazole interface suggests potential extensibility to other metal–ligand combinations, which remains to be explored. This approach provides a facile route toward functional polymer–MOF hybrid interfaces for future applications in biosensors, catalytic surfaces, and porous thin-film devices.
