Stereoselective Seed-Induced Living Supramolecular Polymerization

Area of Science:

• Supramolecular Chemistry
• Polymer Science
• Materials Science

Background:

• Nature utilizes stereoselective and temporally controlled supramolecular polymerizations.
• Living supramolecular polymerization (LSP) enables synthesis of polymers with controlled length and narrow dispersity.
• Achieving stereoselective control in supramolecular polymerization has been challenging due to monomer design constraints.

Purpose of the Study:

• To develop a method for synergistic stereo- and structural control in supramolecular polymerization.
• To realize an unprecedented stereoselective seed-induced living supramolecular polymerization (LSP).
• To design and synthesize chiral, well-defined functional materials.

Main Methods:

• Development of a stereoselective seed-induced living supramolecular polymerization (LSP) approach.
• Utilized bischromophoric naphthalene diimide (NDI) enantiomers with a chiral binaphthyl amine core.
• Demonstrated homochiral and seeded growth experiments.

Main Results:

• Achieved unprecedented synergistic stereo- and structural control in supramolecular polymerization.
• Successfully demonstrated homochiral and seeded growth using designed NDI enantiomers.
• The chiral monomers exhibited strong self-recognition abilities and pathway complexity.

Conclusions:

• Stereoselective seed-induced LSP offers a powerful strategy for creating precisely controlled chiral supramolecular polymers.
• This approach overcomes limitations in designing chiral-discriminating monomers for supramolecular polymerization.
• The developed method paves the way for advanced functional materials with tailored stereochemical properties.
