A fluorescence switch based on a controllable photochromic naphthopyran group

Synthesis of heterocyclic naphthoquinone derivatives as potent organic fluorescent switching molecules

“…At the same time, a photo switchable organic fluorescent material has promising application of optoelectronic, fluorescent probe and fluorescent sensor devices working on the basis of fluorescence properties and inter-conversion of chemical species under the influence of light irradiation [8][9][10].…”

Preparation and photochromic properties of layer-by-layer self-assembly films and light-responsive micelles based on amphiphilic naphthopyran derivative

“…The first one is about photo-controlled fluorescence switching [21][22][23], in which the photoisomerization of naphthopyran molecules can modulate the fluorescent intensities of fluorophores. The second is about the introduction of naphthopyrans into nanostructures (layer-by-layer (LBL) self-assembly films and nanoparticles).…”

Solvent-dependent fluorescence enhancement and piezochromism of a carbazole-substituted naphthopyran

“…So far, diarylethene, spiropyran and spirooxazine derivatives have been extensively studied for constructing fluorescence-photochromism switches, whereas less attention has been paid to NP unit [11][12][13][14]. Up to now, only a few examples using photochromism of naphopyran to modulate the fluorescence via different ways, such as the binding of metal ion and protonation, photoinduced energy and electron transfer have been reported [15][16][17][18]. The photochromic reaction of naphthopyran molecule is illustrated in Scheme 1.…”

“…Recently, our group reported the photochromic fluorescence switching adopting NP as photochromic unit and benzimidazole as fluorescent moiety [17][18][19][20]. Reversible modulation of fluorescence intensity was implemented by the photochromism of NP unit.…”
