A highly soluble poly(1,3,4-oxadiazole) (POD) substituted with long alkyl chains showed reversible electrochemical fluorescence switching between dark (n-doping) and bright (neutral) states. POD film was photo-patterned to obtain high contrast secure images which displayed patterned image reversibly under a step potential of +1.8/−1.8V (vs. Ag/AgCl).
