Developing new visible light-triggered NIR photochromic sensors for the accurate detection of volatile amine vapors in the solid state is highly desirable. Herein, three novel dithienylethene-bridged difluoroboron β-diketonate dyes Di-BF2bdk-DTE1-Di-BF2bdk-DTE3, in which BF2bdk group not only functions as electron acceptor but also responds to amine vapors, have been developed. Upon alternating irradiation with blue light (460-470 nm) and near-IR light (760-770 nm), they displayed excellent NIR photochromism and fluorescent switching behaviors in toluene and in the PMMA film. Moreover, they showed an unprecedented triple sensing performance for volatile n-propylamine vapor in the PMMA film state (fluorescent-colorimetric-colorimetric). Therefore, they would be utilized as triple sensing membranes for selective detection towards volatile primary or secondary amine vapors in environmental and biol. systems.
