A highly selective multi-responsive fluorescence sensor for Zn²⁺ based on a diarylethene with a 4,6-dimethylpyrimidine unit

Abstract

A novel multi-responsive fluorescence sensor based on a diarylethene derivative with a 4,6-dimethylpyrimidine unit was developed for Zn2+ detection.

One-pot preparation of pyrazole “turn on” and “turn off” fluorescent sensors for Zn2+ and Cd2+ directly from chalcones via in situ aromatisation

“…10,11 Standard protocols for screening fluorescent sensors in organic solvents were followed throughout. 31…”

Zinc-Induced Luminescent l-Valine-Based Pseudopeptidic Soft Bioinspired Materials for Precise Tuning of Nanoassembly

“…Therefore, much effort has been oriented toward the judicious design and synthesis of appropriate fluorescence sensors for the quantitative detection and determination of various metal ions. , Zn­(II) ion is an essential element that influences various biological activities that play significant roles in environmental and biological systems. , Zinc is the second most abundant metal ion in the biological system. It is crucial for maintaining normal cellular activities, including cell division, mammalian reproduction, muscle contraction, hormone regulation, protein synthesis, and DNA synthesis. − In the human body, the normal Zn­(II) level is between 200 and 300 mg, and deviation of zinc levels (above or below) from this value can cause many health problems. A deficiency of Zn­(II) may cause several symptoms of diseases, such as brain dysfunction, Parkinson’s disease, immune suppression, skin damage, diabetes, and slow growth .…”
