Fig. 2

a The schematic illustration of the radical diffusion monitoring process. The indicator caused the color of the gel to change from orange to purple upon contact with iron ions. b The results of radical diffusion. c The changes in the LCE precursor before and after adding the APS solution. LCE precursor is composed of 1 g of RM82 and an equimolar amount of EDDET dissolved in 1 g of N, N’-dimethylformamide. d, e FTIR spectroscopy of LCE film before and after soaking in APS solution. All scale bars are 1 cm.
