Abstract

Multi-responsive fluorescent materials have attracted much attention in recent years, but the synthesis routes were always complicated. In this work, a simple method was proposed to fabricate multiple responsive fluorescent microparticles, which could respond to tree types of external stimuli, including temperature, electric potential and H2O2 to change particle size and morphology. These microparticles were easily fabricated from radical polymerization of vinylidene ferrocene and N-isopropylacrylamide. Interestingly, when fluorescein (FITC) was encapsulated in the polymeric microparticles, fluorescence intensity of the obtained assemblies could change significantly with the three stimuli mentioned above. This work may provide a new path for the simple synthesis and construction of multi-responsive fluorescent microparticles.
