Many self-sorting systems have been established by using hydrogen bonds, metal-ligand interactions, solvophobic effects, and reversible covalent bonds. In recent years, the metal-ligand coordination-driven self-sorting has attracted tremendous attention. Several strategies have been developed to increase the degree of self-sorting, for example, by controlling ligand geometry and metal coordination number. Here, we would like to achieve self-sorting of complexation of functionalized 2,2′:6′,2〃-terpyridine ligands with suitable metal ions and to increase the degree of self-sorting by enhancing steric hindrance and inductive effects of the ligands. Electrospray ionization mass spectrometry (ESI-MS) was utilized to identify intact assemblies and to compare the relative stability of hetero-terpyridine complexes. Construction of metallo-supramolecular rod-coil and rod-coil-rod block copolymers was used as a demonstration of this powerful self-sorting process. The resultant block copolymers were well characterized by 1H NMR, DOSY NMR, AFM, and TEM. It was found that the self-assembled morphology could be controlled by adjusting their hydrophilic/hydrophobic ratio.論文使用權限: 不同意授權三聯口比口定自分類self-sortingterpyridinesupramolecular copolymerthesis
