We demonstrate that aldehyde‐substituted donor–acceptor cruciforms [1,4‐bis(arylethynyl)‐2,5‐distyrylbenzenes] are useful dosimeters for primary amines, primary diamines, and secondary amines. The 1, n ‐diamines are particularly reactive towards this dosimeter and can be detected in less than 100 ppm concentration. Using a single aldehyde‐functionalized cruciform in seven different solvents allowed us to discern fourteen different amines by digital photography and statistical evaluation of the response patterns extracted as red, green, blue (RGB) values.
