A three‐component molecular ensemble consisting of the constitutionally dynamic cage 1 , rotaxane 2 and luminophore 3 acts as a signal transducer which assimilates three input signals, i. e., Zn 2+ , H + , and Cu + , to perform individual logic operations (e. g. a 3‐input NOR gate with catalytic output, 3‐input AND gate with optical output) and operates as an unconventional 3‐input demultiplexer.
