The concept and the development of molecular host-guest chemistry has resulted in many fascinating and emerging technologies . The rules of this branch of supramolecular chemistry have been applied to large diversity of materials . Much work in this field has been inspired by the seminal work of Bayer and Wilchek on the avidin-biotin pair that became a general tool in the biological sciences . An example is the use of the complementarity of DNA strains to assemble metallic nanoparticles in larger structures as diagnostic tools by . Chromophores stability and also that of highly unstable compounds such as white phosphorus can be enhanced by selective encapsulation into metal-organic cages . The sieving properties of metal-organic frameworks (MOFs) have been exploited for energy storage, carbon capture and membrane technology . Inclusion of chromophores in these porous crystals opens up many new possibilities for the generation of new optically-functionalized materials by post-assembly . The development of such materials is not trivial. Among many factors, pore size, shape and geometry should obviously be correlated with the nature of the guest molecules. For example, Harris, Guillaume et al. reported organic crystals with multicomponent inclusion and controlled guest arrangements during the growth process . Guest molecules were also placed in different areas and shells of MOFs .
