An AIE-based fluorescent test strip (OPD-TPE-Py-2CN) for rapid and sensitive detection of gaseous phosgene was designed. The fluorescence changes from blue to green upon exposure to phosgene. And the detection limit (1.87 ppm) is lower than the “harmless” level of human response to acute phosgene exposure.
