The fluorophore‐spacer 1 ‐receptor 1 ‐spacer 2 ‐receptor 2 system (where receptor 2 alone is photoredox‐inactive) shows ionically tunable proton‐induced fluorescence off‐on switching, which is reminiscent of thermionic triode behavior. This also represents a new extension to modular switch systems based on photoinduced electron transfer (PET) towards the emulation of analogue electronic devices.
