Description
Summary:•Ruthenium-functionalized microgels were synthesized through the combination of microfluidic-based droplet technique and inter crosslinking of presynthesized functionalized linear polymers.•We perform the microgel synthesis and functionalization under facile conditions and, therefore, significantly reducing some key complexities in the synthesis.•The prepared microgels displayed a variety of complex behaviors, including catalysis of nonlinear chemistry, photo-memory behavior and photo-triggered structural degradation. Ruthenium-functionalized microgels were prepared with the combination of microfluidics-based droplet template approach and the direct crosslinking of two types of functionalized polymers within the droplet “microreactor”. The microgels displayed a variety of properties, including the catalytic capability for Belousov-Zhabotinsky reaction, white light induced structural memory behavior and monochromatic lights triggered photolysis and structural degradation behaviors. The photo degradation mechanism is also proposed and further verified by multiple characterization methods.
