A highly selective fluorescent sensor for Cd 2+ based on a new diarylethene with a 1,8-naphthyridine unit

A highly selective and sensitive fluorescent chemosensor for Zn2+based on a diarylethene derivative

“…[25][26][27][28][29] On the other hand, an increasing number of photochromic molecular systems have been used as uorescent probes to detect metal ions in recent years. [30][31][32] Among these photochromic materials, diarylethenes have attracted increasing attention due to its excellent anti-fatigue for switching the intensity of uorescent emission as well as its potential applications in molecular switching devices. 33,34 Heretofore, a variety of Zn 2+ uorescence chemosensors decorated with diarylethenes have been reported.…”

A bifunctional sensor based on diarylethene for the colorimetric recognition of Cu2+ and fluorescence detection of Cd2+

“…The weak uorescence of 1o was attributed to the isomerization of the C]N bond. 39,59 Aer the addition of Cd 2+ , a stable complex 1o 00 was formed, which inhibited the isomerization of the C]N bond and increased the rigidity of the molecule, resulting in a chelation enhanced uorescence (CHEF) effect. 60,61 The uorescence spectrum of 1o could be recovered by adding 60 equiv.…”

A highly selective fluorescent chemosensor for Mg2+ based on a diarylethene with a quinoxaline unit

“…The fluorescent probes are widely used because it does not need expensive equipment. However, among the fluorescent probes, diarylethene derivatives have drawn the attention of many researchers owing to their advantages—fatigue resistance, thermal stability, and fast response . Furthermore, diarylethene derivatives are the most potential photochromic materials that can be used as optical memory for optical switching devices .…”
