Abstract
The mass transfer in a film of metal-organic framework with one-dimensional pores, oriented perpendicular to the substrate surface, was gravimetrically explored. The diffusion coefficients of the probe molecules cyclohexane and p-xylene were determined from the transient uptake curves. When exchanging cyclohexane by p-xylene in the MOF pores, the mass transfer was significantly slower than the plain, single-component uptakes. However, a single-file-diffusion situation, where mutual passage is hindered, tremendously slowing down the mass transfer, was not found.
