    • John Wiley & Sons, New York, It is noteworthy that DIAZpar rings are not perfectly parallel to either NAPHin or NAPH out, the angles between their planes being 3.0° and 2.5°, respectively The refinement of (9)2 gives values of the indexes that are higher than usual due to the disorder associated with some of the triflate counterions and solvent molecules. However, this disorder does not involve the main structure of the catenane and, therefore, the discussion within the text, as can be observed from the ellipsoid representation included in the supporting information Herein, we report preliminary results about the emission properties of these systems. Further studies on the optical characteristics and the application of these and other related structures are currently ongoing When CH3NO2 is used, only the lowest energy band can be observed due to the strong absorption of this solvent below 360 nm

    • At the concentrations that the fluorescence studies were carried out, some dissociation of the PdII metallocycles into free ligands is possible. Therefore, the quenching observed for catenanes 3 (8)2 and 3 (9)2 could have some contribution from the interaction of ligand 3 with cyclophanes 8 and 9. In the case of the inclusion complexes derived from metallocycle 6a,b ·NO3 the fluorescence quenching can be attributed only to the formation of the inclusion complex, as the interaction between the guests and free ligand is very limited in this concentration range
