“…The basic design approach for these Zn 2+ photoswitchable probes involves coupling a photochromic diarylethene to a ligand structure specific to the target ion (Figure 5). When Zn 2+ binds to the ligand, the resultant complex exhibits a fluorescent response, which can be modulated by the light-controlled "open" or "closed" states of the diarylethene, thus paving the way for the development and application of various related Zn 2+ fluorescent probes [121][122][123][124][125][126][127][128][129][130][131]. Fu et al introduced a sophisticated ratiometric fluorescent chemosensor for Zn 2+ , utilizing a novel diarylethene compound that is covalently bonded to an 8aminoquinoline-2-aminomethylpyridine unit [121].…”

In recent years, significant advancements have been made in the research of photoswitchable probes. These probes undergo reversible structural and electronic changes upon light exposure, thus exhibiting vast potential in molecular detection, biological imaging, material science, and information storage. Through precisely engineered molecular structures, the photoswitchable probes can toggle between “on” and “off” states at specific wavelengths, enabling highly sensitive and selective detection of targeted analytes. This review systematically presents photoswitchable fluorescent and colorimetric probes built on various molecular photoswitches, primarily focusing on the types involving photoswitching in their detection and/or signal response processes. It begins with an analysis of various molecular photoswitches, including their photophysical properties, photoisomerization and photochromic mechanisms, and fundamental design concepts for constructing photoswitchable probes. The article then elaborates on the applications of these probes in detecting diverse targets, including cations, anions, small molecules, and biomacromolecules. Finally, it offers perspectives on the current state and future development of photoswitchable probes. This review aims to provide a clear introduction for researchers in the field and guidance for the design and application of new, efficient fluorescent and colorimetric probes.

“…These showed the derivatives of 8-aminoquinoline in the presence of amide gradually to be acknowledged. Several studies focusing on improving and increasing the sensitivity and selectivity of fluorescent probes for Zn 2+ based on 8-amidoquinoline and its derivatives are widely developed [47,48]. Further, 8-amidoquinoline derivatives exhibit fluorescence properties for sensing Zn 2+ based on important signaling mechanisms and internal charge transfer (ICT) [48,52].…”

Mass-spectrometry-based and X-ray fluorescence-based techniques have allowed the study of the distribution of Zn2+ ions at extracellular and intracellular levels over the past few years. However, there are some issues during purification steps, sample preparation, suitability for quantification, and the instruments’ availability. Therefore, work on fluorescent sensors based on 8-aminoquinoline as tools to detect Zn2+ ions in environmental and biological applications has been popular. Introducing various carboxamide groups into an 8-aminoquinoline molecule to create 8-amidoquinoline derivatives to improve water solubility and cell membrane permeability is also a recent trend. This review aims to present a general overview of the fluorophore 8-aminoquinoline and its derivatives as Zn2+ receptors for zinc sensor probes. Various fluorescent chemosensor designs based on 8-amidoquinoline and their effectiveness and potential as a recognition probe for zinc analysis were discussed. Based on this review, it can be concluded that derivatives of 8-amidoquinoline have vast potential as functional receptors for zinc ions primarily because of their fast reactivity, good selectivity, and bio-compatibility, especially for biological applications. To better understand the Zn2+ ion fluorophores’ function, diversity of the coordination complex and geometries need further studies. This review provides information in elucidating, designing, and exploring new 8-amidoquinoline derivatives for future studies for the improvement of chemosensors that are selective and sensitive to Zn2+.

“…Typically, the fluorine-containing diarylethenes are connected with fluorescent chromophores through single bonds, and this process is associated with huge energy loss in the fluorescence emission process. 11–14 To overcome this drawback, it is essential to combine the fluorine-containing diarylethene and the fluorescent chromophore with a π-conjugated linker, which can alter the emission wavelength and also reduce the energy loss. 15–17 Therefore, chromophores that can be conjugated to fluorine-containing diarylethenes are highly desirable and have gained significant focus.…”
