Abstract
In accordance with the present invention, there is provided a method for preparing a reversible, self-assembly of an imbedded hexameric metallomacrocycle within a macromolecular superstructure. The method occurs by an intramolecular mechanism in which a macromolecular skeleton possesses multiple ligands capable of reversible assembly-disassembly triggered by the presence of metal ions.
Claims14
A method of preparing a metallomacrocycle, the method comprising the steps of:
- preparing an alkene-modified ligand, wherein the ligand is a terepyridine;
- reacting a plurality of ligands with a first source of a metal ion to form a primary hexameric metallomacrocycle;
- crosslinking the primary hexameric metallomacrocycle with a first catalyst;
- forming a self-assembled metallated macrocyclic complex
- and a macromolecular secondary superstructure
- wherein the metallated macrocyclic complex is embedded within the macromolecular secondary superstructure
- disassembling the self-assembled metallated macrocyclic complex by demetallation to form a demetallated macrocycle.
A method of reversibly self-assembling an imbedded metallomacrocycle within a macromolecular secondary superstructure, the method comprising the steps of:
- preparing an alkene-modified ligand, wherein the ligand is a terepyridine;
- reacting a plurality of the alkene-modified ligands with at least a first source of a metal ion to form a primary hexameric metallomacrocycle;
- crosslinking the primary hexameric metallomacrocycle with a first catalyst;
- forming a self-assembled metallated macrocyclic complex
- and a macromolecular secondary superstructure,
- wherein the metallated macrocyclic complex is embedded within the macromolecular secondary superstructure
- disassembling the self-assembled metallated macrocyclic complex by demetallation to form a demetallated macrocycle.
