Simple but effective! 8‐Methoxyquinoline, an unsophisticated fluorophore, displays both 2:1 multiplexer and 1:2 demultiplexer digital functions (see picture). Protonation of the fluorophore results in completely different optical spectral profiles and multiplexing/demultiplexing behavior is obtained by exploiting the proton‐driven reversible modulation of two complementary absorption and fluorescence signals.
