Photoswitching electrospun nanofiber based on a spironaphthoxazine–isophorone-based fluorescent dye system

A bistable photoswitching photochromic spironaphthoxazine/isophorone-based fluorescent dye system was investigated. The photoregulated fluorescence switching behavior of a spironaphthoxazine/isophorone dye loaded poly(methyl methacrylate) nanofiber was also studied. Reversible modulation of fluoresc...

Description
Summary:A bistable photoswitching photochromic spironaphthoxazine/isophorone-based fluorescent dye system was investigated. The photoregulated fluorescence switching behavior of a spironaphthoxazine/isophorone dye loaded poly(methyl methacrylate) nanofiber was also studied. Reversible modulation of fluorescence intensity was achieved using alternating irradiation with UV and visible light. The erasable and rewritable optical storage based on spironaphthoxazine/isophorone dye loaded poly(methyl methacrylate) nanofiber has been developed. ► A photoswitching spironaphthoxazine/isophorone dye system was investigated. ► The photoregulated fluorescence switching behaviour of the nanofiber was examined. ► Reversible modulation of fluorescence intensity was achieved. ► The erasable and rewritable optical storage of the nanofiber was developed.
