Novel supramolecular polymers are synthesized from lysine peptides and carbon dioxide (CO2). These switchable materials can trap and release molecules, offering versatile applications in materials science.
Area of Science:
- Supramolecular Chemistry
- Polymer Science
- Biomaterials
Background:
- Supramolecular polymers offer tunable properties through non-covalent interactions.
- Developing stimuli-responsive materials from biocompatible sources is a key research area.
Purpose of the Study:
- To design and synthesize novel linear and cross-linked supramolecular polymers.
- To utilize biologically friendly lysine peptides and carbon dioxide (CO2) as building blocks.
- To investigate the switchable and molecule-trapping capabilities of these polymers.
Main Methods:
- Synthesis of supramolecular polymers via bubbling CO2 through solutions of lysine peptides in organic solvents.
- Characterization of polymer structures and properties.
- Demonstration of molecule entrapment and release using a model dye.
Main Results:
- Successful formation of supramolecular polymers from specific lysine peptides and CO2 at ambient temperatures.
- Polymers exhibit gelation, are isolable, storable, and thermally reversible to monomers.
- Demonstrated switchable properties and ability to trap, store, and release foreign molecules like coumarin 2.
Conclusions:
- Biologically friendly lysine peptides and CO2 can form novel, switchable supramolecular polymers.
- These materials possess tunable physical properties and قابلیت for molecular encapsulation.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
