A double target fluorescent sensor based on diarylethene for detection of Al3+ and Zn2+

A visible-light-gated donor–acceptor Stenhouse adduct chemosensor: synthesis, photochromism and naked-eye colorimetric/fluorometric sensing of Al3+ and Zn2+

“…After complexing with metal ions, the fluorescence intensity enhances due to the formation of a rigid chelate to inhibit –CN– isomerization. 15–20 Roy et al recently reviewed the dual chemosensors for metal ions, which plays a guiding role in exploring the response of dual metal ions. 21…”

“…After complexing with metal ions, the fluorescence intensity enhances due to the formation of a rigid chelate to inhibit -CNisomerization. [15][16][17][18][19][20] Roy et al recently reviewed the dual chemosensors for metal ions, which plays a guiding role in exploring the response of dual metal ions. 21 Recently, various photochromic compounds have been constructed as chemosensors for metal ions, and their main strategy is to combine responsive functional groups with photochromic molecules.…”

A Naphthol and Nitroaniline‐Based Dual‐target Chemosensorfor Fluorometric Sensing of Al3+ and Colorimetric Sensing of Fe3+

“…[2][3][4] However, aluminum accumulated in excess in the body causes diseases such as mild depression, Parkinson's disease, fatigue, memory loss, and Alzheimer's disease. [5][6][7] Therefore, it is needed to develop analytical tools that selectively sense Al 3 + ion. [8,9] Iron usually has the two oxidation states of ferrous ion (Fe 2 + ) and ferric ion (Fe 3 + ), which play important roles in the body, such as enzymatic catalysis, oxygen transport, electron transport, and cellular metabolism.…”

“…Aluminum is plenty in the earth‘s crust [1] and is widely used in various fields like medical purposes, the manufacturing industry, food additives, and packing materials [2–4] . However, aluminum accumulated in excess in the body causes diseases such as mild depression, Parkinson‘s disease, fatigue, memory loss, and Alzheimer‘s disease [5–7] . Therefore, it is needed to develop analytical tools that selectively sense Al 3+ ion [8,9] …”

Immediate detection of Co2+ by a phthalazine‐based colorimetric chemosensor

“…Up-to-date, diverse analytical techniques like fluorescence, [15][16][17][18][19][20][21][22] atomic absorption spectroscopy, 23,24 the electrochemical method, 25,26 voltammetry and inductively coupled plasma mass spectrometry have been developed for metal-ion sensing. [27][28][29][30] However, some methods rely on the use of highly sophisticated instruments that are expensive and require operators with the necessary expertise.…”
