Therefore, developing an accurate and highly sensitive detection method is of critical importance. In this work, we have synthesized a sulfo-cyanine-based dye (CyNH) for the selective rapid detection (&lt;1 min) of phosgene by Near-IR turn-on colorimetric and fluorescence responses. Notably, CyNH exhibited a 3-fold fluorescence enhancement at 756 nm accompanied by a distinct color change from light blue to dark blue by the appearance of strong absorption signal at 600 nm, with a detection limit of 1.17 ?M. To enable on-site detection, a 3D-printed sensor of the CyNH-coated 3D-printed substrate was developed, which shows visible color changes upon exposure to phosgene. Furthermore, integration of this sensor with a smartphone camera and its processing capabilities allows for real-time quantification of phosgene concentrations by eliminating the need for costly analytical instruments. To the best of our knowledge, the development of an NIR probe enabling dual colorimetric and fluorescent NIR detection of phosgene using a 3D-printed sensor is scarcely reported. This innovative 3D-printed, smartphone-assisted sensing platform offers a practical and sustainable approach for future phosgene detection applications in various fields. 2026 American Chemical Society Subject The topic of the resource 3D-printed sensor; colorimetric; cyanine; fluorescence; near-IR; phosgene Publisher An entity responsible for making the resource available American Chemical Society Relation A related resource ISSN: 27719855; Language A language of the resource English Type The nature or genre of the resource Article Rights Information about rights held in and over the resource Restricted Access; Hardcopy may be available in the library Format The file format, physical medium, or dimensions of the resource online
