A switchable electrochromism and electrochemiluminescence bifunctional sensor based on the electro-triggered isomerization of spiropyran/layered double hydroxides†
Abstract
A bifunctional ultrathin film (UTF) electrode was fabricated based on layered double hydroxides (LDHs) and spiropyran (SP), which exhibited electrochromism and electrochemiluminescence (ECL) sensing behavior toward temperature and Zn2+ ions.
