Description
The modelling of adsorption or confinement of organic molecules in zeolite crystals is a long story, not only because of the infinite possibilities offered by the intrinseque properties of the guest molecules and of the framework topologies.
The simplest family of such inclusion compounds is probably the (dye@zeolite) one. A priori the properties arising from the inclusion of simple dyes, hyperpolarisable molecules or photochromes in the microporous channels mainly depends on the zeolite topology and not of charge compensating cations as for gas separation or catalysis process. However the structures generally inferred from ab initio calculations or/and powder XRD lack reliability.
I will present few examples showing assets of of neutron scattering for the comprehension of such systems.
