irradiation with blue light (460–470 nm) and near-infrared 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
迫切需要开发新的可见光触发的近红外光致变色传感器,以精确检测固态中的挥发性胺蒸气。在此,已经开发了三种新颖的二
