Based on the chemical‐sensitive fluorescence emission behaviors of the molecular switch 4‐bromo‐5‐methoxy‐2‐(2‐pyridyl)thiazole ( 2‐BMPT ), the communication of logic information between two functional units has been realized. With the rational control of the protonation and coordination reaction of 2‐BMPT , an upstream switching unit (a 1:2 demultiplexer) and two downstream data‐processing units are involved and interconnected in the communication. The two output states of the 1:2 demultiplexer serve as the initial input states of the two parallel downstream data‐processing units, which execute the information communication between the two circuit layers. Furthermore, in the parallel data‐processing layer, the logic gates of INHIBIT and YES accomplish their specific logic functions. Therefore, a molecular cascade circuit composed of an upstream switch and two downstream processing units has been constructed based on the chemical‐modulated fluorescence properties of 2‐BMPT .
