The two materials, XFAI06 and XFAI07, are themselves NIR-II fluorescent molecules, but because of their aggregation-induced luminescence properties, they can also be called AIE molecules. If you need to use the direction of aggregation-induced luminescence, you can choose these two products. They are good choices for in vivo functional imaging of large animals,including large depth microscopic imaging of living cerebral blood vessels in rats, visual stroke imaging and major organs (gastrointestinal tract and bladder) imaging.
