The design and synthesis of polymer-based metallomacrocycles relying on metal-ligand interactions remain a challenge in the polymer field. Instead of utilizing chem. reactions to synthesize macrocycles, a general approach is proposed to construct metallomacrocyclic structures through supramol. self-assembly of a specific macroligand with suitable transition metal ions. Therefore, a new ditopic macroligand (L) consisting of PEG end-capped with 2,6-bis(1,2,3-triazol-4-yl)pyridine derivatives is prepared via CuAAC “”click”” reaction. Four types of metal (Fe2+, Zn2+, Ni2+, and Cu2+) complexes are obtained by simply mixing a solution of metal ions and L in appropriate concentrations The investigation of the coordination chem. suggests that coordination of L with Cu2+ results in the formation of a [1+1] metallomacrocycle, while the other metal complexes exclusively lead to the formation of linear metallopolymers and/or larger aggregates. This work provides new insights into designing metallomacrocycles and may have potential application in the synthesis of catenanes and other cyclic or cycle-based topol. architectures.

2,6-Dibromopyridine(cas: 626-05-1) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. Reference of 2,6-Dibromopyridine
