Spectroscopic changes from a solution of the amphophile 5,10,15,20-tetraphenylporphyrin in N,N-dimethylformamide using inputs of acid (HClaq) and base (KOBut) are interpreted as XOR and INHIBIT logic operations. The combination of these two operations gives rise to a device that acts as a molecular half-subtractor.
