The design and self-assembly of two new flexible supramolecular nanoballs are described. These assemblies incorporate two flexible tritopic amide and ester building blocks and were prepared in excellent yields (96−97%) via coordination driven self-assembly. The first resulted from the reaction of 4 equiv of a new tritopic ester ligand N,N‘,N‘ ‘-tris(4-pyridylmethyl) trimesic ester and 3 equiv of C4 symmetric Pd(NO3)2. The second analogous structure was obtained by the self-assembly of a flexible N,N‘,N‘ ‘-tris(3-pyridylmethyl) trimesic amide and Pd(NO3)2. The assemblies were characterized with multinuclear NMR spectroscopy, electrospray ionization mass spectroscopy, elemental analysis, and TGA. Mass spectrometry along with NMR data and TEM view confirms the existence of the two assemblies. MM2 force field simulations of the cages showed a ball shape with the diameter of the inner cavity of about 2.1 and 1.8 nm for 2a and 2b, respectively, which were also corroborated by TEM analysis.
