“…Unlike normal singleselective chemosensors, detection and analysis of multiple ions via a single fluorescent probe that possesses diverse spectral properties is not only cost-efficient, time-saving and labor-saving, but also beneficial for operational efficiency and simplicity with reducing environmental pollution. Accordingly, constructing simple, novel and multiple-ion responsive fluorescent probes has become a promising research focus [4][5][6][7][8][9][10][11][12].…”

Construction of fluorescent probes for zinc ion (Zn2+) and cadmium ion (Cd2+) is significant for the safety of humans. However, the discriminating recognition of Zn2+ and Cd2+ by a single probe remains challenging owing to their similar properties. Herein, a novel deoxycholic acid derivative containing 8‐hydroxyquinoline fluorophore has been facilely synthesized through click chemistry to form a clamp‐like probe. Using its perfect bonding cavity from 1,2,3‐triazole and quinoline, this molecule showed favorable solvent‐dependent fluorescent responses and distinguished Zn2+ and Cd2+ in different solvents. In ethanol aqueous solution, it displayed good selectivity and ratiometric fluorescence to Zn2+ with 30 nm spectroscopic red‐shifts. In acetonitrile aqueous solution, it exhibited good selectivity and ratiometric fluorescence to Cd2+ with 18 nm spectroscopic red‐shifts. Moreover, the unique microstructural features of the probe in assembly were used to reflect its recognition processes. Due to its merits of low detection limit and instant response time, the probe was utilized for sensing Zn2+ and Cd2+ in water, beer and urine with high accuracy. Meanwhile, this probe served as a handy tool and was employed to obtain inexpensive test strips for the prompt and semiqualitative analysis of Zn2+ and Cd2+ with the naked eye.

“…There are various methods for the detection of metal ions, such as atomic spectrometry, electrochemical analysis, fluorescence spectrometry, UV-visible spectrometry, the biochemical method, the colorimetric method, etc., which have their own advantages and disadvantages. Fluorescence spectrometry has become the most common method for metal ion detection because of its high sensitivity, as well as its simplicity and rapidity compared with other methods [2,3].…”

The naphthalene derivative fluorescent probe F6 was synthesized and a 1 × 10−3 mol/L solution of Al3+ and other metals to be tested was prepared for the subsequent experiments. The Al3+ fluorescence system of the naphthalene derivative fluorescent probe F6 was successfully constructed as demonstrated by fluorescence emission spectroscopy. The optimal time, temperature and pH of the reaction were investigated. The selectivity and anti-interference ability of the probe F6 for Al3+ were investigated by fluorescence spectroscopy in a methanol solution. The experiments showed that the probe has high selectivity and anti-interference ability for Al3+. The binding ratio of F6 to Al3+ was 2:1, and the binding constant was calculated to be 1.598 × 105 M−1. The possible mechanism of the binding of the two was speculated. Different concentrations of Al3+ were added to Panax Quinquefolium and Paeoniae Radix Alba. The results showed that the recoveries of Al3+ were 99.75–100.56% and 98.67–99.67%, respectively. The detection limit was 8.73 × 10−8 mol/L. The experiments demonstrated that the formed fluorescence system can be successfully adapted for the determination of Al3+ content in two Chinese herbal medicines, which has good practical application.
