The synthesis of six new, functionalized 180 pyridyl donor ligands and their coordination-driven self-assembly into supramolecular rectangles is reported. Three of the new donors have been functionalizedwith hydrophobic straight chain alkane units (C₆, C₁₂, and C₁₈) while the remaining three have beenfunctionalized with derivatized di-, tetra-, and hexaethylene glycol hydrophilic units (DEG, TEG, andHEG, respectively). The resulting self-assembled hydrophobic and hydrophilic supramolecular rectangleshave been fully characterized by multinuclear NMR and electrospray ionization mass spectrometry.Molecular force field modeling suggests that the functionalized rectangles range in size from roughly3.0 × 2.9 to 3.0 × 6.0 nm² in size.
