The concept of kinetic selectivity sensing demonstrated for ZIF-8 can be readily extended to other materials within the MOF family, such as ZIF-7. In ZIF-7, which has a similar cage-andwindow structure but slightly smaller pore apertures, the diffusivities of the VOCs are up to two orders of magnitude lower than in ZIF-8 (SI Fig. ). Leveraging the diversity of MOF structures will enable shifting fast-diffusion molecules into a measurable range and promises further possibilities to improve selectivity by combining sensors based on different materials.
