Key Points

To investigate how different solvents and acid concentrations affect the gelation process of dipeptide-based gelators.
Utilized tert-butyl containing solvents for gelation experiments.
Employed two tBu-protected dipeptide precursor gelators.
Analyzed gelation behavior and network morphology under varying acid concentrations.
Demonstrated that solvent choice significantly influences gelation effectiveness.
Showed changes in network morphology based on solvent and acid concentration variations.
Found that material stability varies with different solvent-induced gelation parameters.

Abstract

The tunability of solvent-induced gelation mechanism using tert-butyl (tBu) containing solvents and two tBu-protected dipeptide precursor gelators (Boc-Phe-Phe-OtBu 1 and Boc-Leu-Phe-OtBu 2) is reported. Gelation behaviour, network morphology, material stability,...
