Colorless, highly toxic phosgene is long considered a great menace to human health and national security. An excellent aggregation-induced emission (AIE) + TICT characteristic ratiometric colorimetric fluorescent sensor, TPE-CI, was constructed by combining a TICT-based 3-benzo[d]imidazole-chromen-2-imine with an AIE-based tetraphenylethene (TPE) unit. A TPE-CI probe detects phosgene in organic solvents by a change from the TICT process to the AIE process, but also in solids by a new change from the AIE + TICT process to the AIE process. TPE-CI exhibited convenient use as a test strip with rapid response (<6 s in solvent; 2 min in air atm.) and excellent and fair sensitivities for visual inspection of trace phosgene in organic solvents and as a gas. A calculated limit of detection was 0.36μM in solvent and 0.27 ppm in air, far below the acute phosgene exposure level for human response. Satisfactory results indicated this AIE + TICT strategy may offer valuable thinking to develop convenient solid-state optical sensors with dual ratiometric and colorimetric fluorescence response for gaseous phosgene identification. In the part of experimental materials, we found many familiar compounds, such as Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8Application In Synthesis of Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine)
