Based on the photo-induced electron transfer(PET) mechanism, a redox-aetive fluorescent molecular bistable switch was obtained with ferrocene as a reversible redox-control of PET and fluorophore anthracene as signaling unit. The fluorophore emission behaviors were studied under different conditions. With various chemicals as input signals and emission intensity under different conditions as output signals, the protonation and oxidation were used to realize the molecular logic function. The inputs and corresponding outputs give an excellent correlation with the truth table for a digital AND logic gate at molecular level.
