protocols based on Cu(I) template synthesis and “click” reactions for the synthesis of functionalized [2]catenanes are described. A straightforward procedure, involving high dilution conditions at high temperatures (70 °C), affords [2]catenanes bearing two identical peripheral groups in high yields. For the preparation of non-symmetrically functionalized [2]catenanes, a second milder and simpler protocol
of a formyl-fullerenoporphyrinbuildingblock. Condensation of this aldehyde with pyrrole in CHCl3 with BF3·Et2O as catalyst followed by p-chloranil oxidation yielded a pentaporphyrinic scaffold surrounded by four peripheral C60 subunits. By following a similar strategy, a bis-porphyrin buildingblock bearing an aldehyde function was prepared and used for the construction of a nonaporphyrin array by

Two benzothiadiazole-based COFs, constructed using “two-in-one” monomers, exhibit significantly different photocatalytic hydrogen generation performances due to their distinct imine bond orientations.
