Fluorescence‐switch‐based logic devices are very sensitive compared with most of the reported devices based on UV/Vis absorption systems. Herein, we demonstrate that a simple molecule, 5,10,15,20‐tetra‐(4‐aminophenyl)porphyrin (TAPP), shows protonation‐induced multiple emission switches through intramolecular charge transfer and/or aggregation‐caused quenching. Highly sensitive INHIBIT and XOR logic gates can be achieved by combining the intermolecular assembly with the intramolecular photoswitching of diprotonated TAPP (TAPPH 2 2+ ). In addition, molecular simulations have been performed by DFT for a better understanding of the emission‐switching processes.
