Modulation of a fluorescence switch of nanofiber mats containing photochromic spironaphthoxazine and D-π-A charge transfer dye

▶ We have designed PMMA nanofiber mats containing a photochromic SPO and fluorescent TCF. ▶ Photoswitchable PMMA nanofiber mats containing SPO/TCF were prepared by electrospinning. ▶ Reversible modulation of fluorescence intensity was achieved by irradiation with UV/vis.
