Key Points

Develop a photo-driven model based on the Curtin-Hammett principle for controlling chemical equilibria.
Established a photochemical model for light-driven information ratchets.
Synthesized microgels with varying crosslinker content and characterized their responsiveness to temperature and pH.
Developed a reliable protocol for light-controlled imine exchange in microgels.
Confirmed the significance of acid in forming a reactive oxonium intermediate affecting condensation kinetics.
Demonstrated successful integration of functional amines into microgel cores via light-gated imine exchange.
Showed that the imine exchange process is reversible, reinstating the release of trifluoromethylated benzylamine.

Implication

Demonstrates a new light-gated imine exchange method in microgels, suggesting advancements in molecular machines.
