A multichannel device for information encryption that uses two fluorescent positional isomers of quinoxaline derivatives is reported. The asymmetry in their electron distribution results in distinguishable acid‐/pH‐responsive emissions that can be separately collected in different fluorescent channels. Thus, the reliability of the encryption can be improved by a minimal compositional difference and responsive mechanism on the molecular level. More information can be found in the Communication by N. Merbouh, F. F. Loeffler, et al. (DOI: 10.1002/chem.202103441).
