Area of Science:

Materials Science
Soft Electronics
Supramolecular Chemistry

Background:

Fluorescent hydrogels (FH) show promise for soft electronics but face challenges in mechanical stability and printability.
Existing methods struggle to prevent aggregation and self-quenching of fluorescent components within hydrogel networks.

Purpose of the Study:

To develop mechanically stable and printable fluorescent hydrogels.
To enhance fluorescent performance and stability for applications in soft electronics and 3D printing.

Main Methods:

Co-assembly of peptide hydrogelators with transition metal ions.
Covalent linking of ligands to peptide hydrogelators for precise metal ion capture.
Incorporation of metal-ligand complexes to stabilize the hydrogel network.

Main Results:

Achieved optically transparent, highly fluorescent hydrogels.
Demonstrated prevention of chromophore aggregation and self-quenching.
Created a white light fluorescent supramolecular hydrogel using three different metal ions.
Confirmed printability of the hydrogels into various patterns.

Conclusions:

The developed fluorescent hydrogels exhibit enhanced stability and fluorescence.
Metal ion incorporation via ligand-assisted co-assembly is an effective strategy.
These hydrogels are suitable for extrusion-based 3D printing in soft electronics fabrication.
