The reversible photoswitched near‐infrared‐(NIR)‐emitting Boron‐dipyrromethene (BODIPY) containing nanparticles are reported. Dithienylethene derivatives are used as the photochromic unit in the nanoparticle to control the on and off of fluorescence BODIPY molecules. As a result, it is demonstrated that these nanoparticles conduct robust reversible modulation of the NIR fluorescence in vitro and in the cell culture with negligible toxicity. This study may offer a new approach to the use of these nanomaterials for numerous photonic and biophotonic applications.
