Supramolecular Gel Formation Based on Glycolipids Derived from Renewable Resources

Area of Science:

• Supramolecular Chemistry
• Materials Science
• Organic Synthesis

Background:

• Self-assembled supramolecular gels from natural molecules offer promising applications.
• A versatile synthetic strategy for structural analogues is needed.
• Renewable resources are increasingly important for sustainable chemistry.

Purpose of the Study:

• To develop a facile synthetic method for glycolipids from renewable resources.
• To investigate the gelation behavior of synthesized glycolipids.
• To characterize the self-assembly mechanism and properties of the formed hydrogels.

Main Methods:

• Synthesis of glycolipids using cashew nut shell liquid and d-glucose.
• Gelation studies across various solvents and oils.
• Morphological analysis (SEM), CD spectroscopy, XRD, FTIR, and rheological analysis.

Main Results:

• A glycolipid was synthesized in good yield from renewable feedstocks.
• Compound 5b exhibited hydrogel formation with a low critical gelator concentration (0.29% w/v).
• Characterization revealed twisted fibers, an entangled network, and self-assembly driven by hydrogen bonding, hydrophobic, and π-π stacking interactions.

Conclusions:

• A facile synthesis of glycolipids from renewable resources was achieved.
• The synthesized glycolipid demonstrates excellent hydrogel-forming ability.
• The study provides insights into the self-assembly of supramolecular gels, crucial for their application in soft materials.
