Abstract: The phenomenon of dynamics in confined state is tightly bound to the dynamical processes that occur in porous materials and condensed (solid) state. In conditions when the available space for a given molecule shrinks to its own size or just several times more its behavior undergoes a drastic change affecting such basic properties like molecular ordering in the system, the possible reaction pathways, but primarily the transport phenomena. This is especially important for new functional materials based on microporous coordination materials, such as metal-organic frameworks. For many applications like the proton conductors, molecular sieves and heterogeneous catalysts, the dynamics of confined species regulates the core functionality of the system. This presentation regards several practical examples in different fields of applications of microporous materials where the confinement plays a particularly important role. The main focus will be put on the combined use of different experimental techniques to probe the mobility of the confined molecular species and the importance of use of the structural data as a reference to build a realistic motional mechanism.
