Abstract
A method was developed for the preparation of temperature-responsive multifunctional nanoreactor by coating the poly (N-isopropylacrylamide) (PNIPAM) on the external surface of silica/lanthanide-POMs/Au spheres. The nanoreactor showed the repeated on/off catalytic activity and switchable luminescence by temperature stimuli. For example, the nanocomplexes showed strong red luminescence in solution and excellent catalytic activity in the reduction of 4-nitrophenol at 25°C. However, when the temperature was 40°C, the red luminescence almost disappeared in solution and catalytic activity was sharply decreased. Moreover, in solutions of K4Fe(CN)6 containing Na2SO4 at 25°C, it demonstrated the well-defined cyclic voltammograms (CV) peaks with large peak currents, showing the “on” state; at 40°C, the CV response was significantly suppressed, showing the “off” state. The smart nanoreactors have great potential for applications in many fields, such as bio-materials, controlled labeling catalysis, switches and so on.
