Template‐Mediated Control over Polymorphism in the Vapor‐Assisted Formation of Zeolitic Imidazolate Framework Powders and Films

A template-mediated MOF-CVD (metal—organic framework-chemical vapor deposition) method was developed for the syntheses of MOFs in both powder and thin-film forms. The time-resolved in situ synchrotron small-angle X-ray scattering reveals that introducing template vapor into the MOF-CVD process precludes transformation into a dense phase, thus resulting in the porous structure.
