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 fluores- cence 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.

    A new and simple quinoline-based fluorescent probe for discriminative sensing of Zn2+ and Cd2+ has been synthesized by inserting an amide group into the 8-aminoquinoline fluorophore and a propargylamine chelating site. This easily-available chemosensor displayed selective and distinct ratiometric fluorescence responses to Zn2+ in almost totally water solution through its amide tautomer binding form, and to Cd2+ in CH3CN aqueous medium through its imidic acid tautomer binding form, respectively. Moreover, the in situ prepared probe 1–Zn2+ complex could act as a relay fluorescent sensor selectively toward pyrophosphate (PPi) and adenosine 5’-triphosphate (ATP) anions via further complexation. Thus, with good specificity, low detection limits and fast response time, a highly efficient fluorescence platform for simultaneous multi-analyte detection has been developed by using the uncomplicated single molecule. Finally, this multi-functional probe was applied successfully for analysis of all the target ions in the tap water sample and on test paper strips, and bioimaging of Zn2+ in mung bean sprouts with low phytotoxicity.

    A new and simple 8-aminoquinoline–rhodamine conjugate-based fluorescent probe was constructed. This chemosensor displayed simultaneously significant fluorescent enhancement for Cr3+ in CH3CN solution and Cu2+ in ethanol solution with high selectivity and sensitivity. The solvent-dependent binding modes provided facile and efficient dual-analyte fluorescent detection. Besides, the concomitant differentiable colorimetric changes with Cr3+ and Cu2+ in CH3CN medium contributed easy and sensitive analysis of both cations by absorbance measurements and naked eyes. Finally, the probe was applied to detect Cr3+ and Cu2+ on silica gel plates.

    A novel fluorescent and colorimetric probe containing deoxycholic acid and rhodamine moieties was developed by click chemistry, and its cascade selective detection of ferric ion (Fe3+) and pyrophosphate (PPi) was investigated in details by spectral measurements. The probe displayed turn-on orange fluorescence and colorless to pink color change upon binding with Fe3+ by reversibly forming the metal complex and opening the spirolactam ring of rhodamine. Through a tandem ligand exchange, PPi with higher affinity for Fe3+ removed the metal from the complex and restored the spectral signal of the probe. The experimental results suggested that this novel molecule could serve as an efficient and economical dual signal chemosensing system for cascade bi-target analysis of Fe3+ and PPi with high selectivity, low detection limits and fast response time. Notably, this bi-functional probe also showed excellent performances in monitoring Fe3+ and PPi on silica gel plates, in water samples and living cells.

    In this work, a novel and simple deoxycholic acid-based fluorescent probe for solvent-dependent multi-detection of Cu2+, C2O42– and P2O74– has been facilely constructed by click chemistry. This probe displayed sensitive recognition toward Cu2+ in low-water-content CH3CN aqueous solution (CH3CN–H2O, 99/1, v/v) via strong fluorescence quenching. Whereas, in DMSO–H2O medium (1/1, v/v), it exhibited significant fluorescent enhancement for C2O42– and P2O74– over a wide range of tested anions. Moreover, with low detection limits and fast response time, the developed fluorescent molecule was used successfully for analysis of the target ions on test paper strips and in water samples.

 

 

Zhen Zhang*, Yuan Zou, Chengquan Deng, Liesu Meng. A simple rhodamine hydrazide-based turn-on fluorescent probe for HOCl detection. Luminescence, 2016, 31, 997.

    Hypochlorous acid (HOCl) plays a crucial role in daily life and mediates a variety of physiological processes, but abnormal levels of HOCl has been associated with numerous human diseases. It is therefore of significant interest to establish a simple, selective, rapid, and sensitive fluorogenic detection of HOCl in environmental and biological samples. A hydrazide-containing fluorescent probe based on a rhodamine scaffold was facilely developed that could selectively detect HOCl over other biologically relevant reactive oxygen species (ROS), reactive nitrogen species (RNS), and most of the common metal ions in vitro. By an irreversible oxidation–hydrolysis mechanism, upon HOCl-triggered opening of the intramolecular spirocyclic ring during the detection, the rhodamine hydrazide-based probe exhibited large fluorescence enhancement in the emission spectra with fast response, low detection limit, and comparatively wide pH detection range in aqueous media. The probe was further successfully applied to monitoring trace HOCl in real tap water and imaging both exogenous and endogenous HOCl within living cells. It is anticipated that the simple and useful probe might be an efficient tool to facilitate more HOCl-related chemical and biological researches.

    A simple rhodamine hydrazide-based fluorescent turn-on probe was developed for fluorescence detection of hypochlorous acid (HOCl) in aqueous media and living cells. On the basis of a HOCl-mediated oxidation-hydrolysis mechanism, this new probe features high sensitivity, comparatively wide pH detection range, fast-response, and great photostability toward HOCl in aqueous solution. Owing to its hydrazide structure, the probe also exhibits excellent selectivity for HOCl over a panel of biologically relevant reactive oxygen species (ROS), reactive nitrogen species (RNS), and most of the common metal ions in neutral buffer. Particularly, with cell membrane permeability and low cytotoxicity, the probe is capable of responding to intracellular changes in HOCl levels in living cells by fluorescence imaging and flow cytometry.

    A rhodamine 6G hydrazide fluorescent chemosensor was prepared for the rapid HOCl detection in aqueous media. The system makes good use of the irreversible HOCl-mediated selective oxidation reaction to generate fluorescent response proportional to the amount of HOCl in neutral buffer. This probe exhibits great photostability, high sensitivity, and good selectivity for HOCl over other reactive species and most of the common metal ions. Furthermore, the probe is cell membrane permeable, and its applicability has been successfully demonstrated for fluorescence imaging of both exogenous and endogenous HOCl within living cells. Cytotoxicity assays prove that this probe is almost nontoxic to the cultured cell lines under the experimental conditions.
