Photocontrolled reversible modulation of lanthanide luminescence in mesoporous silica nanospheres by photochromic diarylethenes

Abstract

Reversible modulation of the luminescence properties of Ln3+ ions has found many applications in the fields of biology, information and chemistry. However, it is still a challenge to efficiently remote...

Recent Development of Photochromic Polymer Systems: Mechanism, Materials, and Applications

“…With the development of technology, monochromatic fluorescence encryption [ 107 ] and anti-counterfeiting [ 108 ] can no longer meet the needs of people. To achieve encryption of different color fluorescence [ 105 ], Jiang et al.…”

Photochromic diarylethene induced fluorescence switching materials constructed by non-covalent interactions

“…Therefore, both competitive absorption and FRET can quench the luminescence of Eu 3+ ions, which will greatly improve the sensitivity of luminescence switching. 83 Although photo-controlled modulation of Ln 3+ luminescence by photochromic DAEs has been widely reported, it is usually performed in organic solvents or solid state. In 2021, Li and colleagues developed a water-soluble photoswitchable supramolecular coordination polyelectrolyte (SCP) by the electrostatic assembly of a cationic photochromic DAE (compound 9 in Fig.…”

Reversible trans-to-cis photoisomerization and irreversible photocyclization reactions of a Co-coordinated stilbene derivative on chiral di-β-diketonate lanthanide complexes

“…[27][28][29][30][31] Photochromic molecules such as spiropyrans (SPP) and diarylethenes (DTE) have been introduced into lanthanide complexes to study their photo-stimuli properties, where photo-control of the isomerization of the SPP unit allows reversible absorption/luminescence modulation ability by regulating the uorescence resonance energy-transfer mechanism between the SPP acceptor and the lanthanide donor. [32][33][34] Light-controlled luminescence ON-OFF switchable hybrid materials can be synthesized by loading Eu 3+ complexes and DTE into monodisperse mesoporous silica nanospheres, 35 and efficient photo-modulation of Eu(III) and Yb(III) luminescences using DTE ligands has been achieved for optical encryption. 36 We have studied a series of lanthanide complexes functionalized with the photoisomerizable azobenzene (AZO) molecule that allow excellent reversible trans-to-cis photoisomerization of AZO using different-wavelength-light stimuli with good fatigue.…”
