✦ Synopsis
The functionalized ligands 1 and 2 bearing hydrogen-moderate selective increase of the fraction of the [(1a) 2 Cu] + or [(1b) 2 Pd] 2+ complex depending on the Janus substrate bonding recognition groups have been synthesized. Their assembly by metal ions such as Cu I and Pd II having different used. Largest enhancements are observed for those Janus substrates that may be expected to display highest coordination geometries generates different receptor architectures for the binding of suitable substrates. Addition geometrical complementarity with the two complexes. These results represent a process directed by target binding based of the complementary bis(imide) Janus molecules (4-7) to [1a, 2a, CuTf] or to [1b, 2b, Pd(BF 4 ) 2 ] mixtures leads to a on dynamic combinatorial chemistry.
