The dual chromogenic and fluorogenic chemodosimetric behaviour of substituted 5‐amino‐1,2‐dihydro‐2‐methyl‐1,6‐naphthyridine‐8‐carbonitriles was investigated. The reaction‐based indicators operate by an unusual rearrangement followed by ring contraction to generate a pyrrolopyridine, with a “naked‐eye” response and chromofluorogenic selective sensing for Cu 2+ ions. The structure of the pyrrolopyridine was confirmed by single‐crystal X‐ray analysis.
