“…Traditional methods such as atomic absorption spectrometry and inductively coupled plasma mass spectrometry, though accurate, are often cumbersome and not suited for quick or in-field measurements. Photoswitchable fluorescent probes uniquely tune their spectral responses to precisely detect Mg 2+ and Ca 2+ ions, emitting distinct fluorescence at specific wavelengths, which enhances detection accuracy by minimizing spectral overlap [ 98 , 99 , 100 , 101 , 102 , 103 ]. Additionally, these probes offer adjustable fluorescence signals that can be dynamically controlled with external stimuli, allowing for real-time, responsive monitoring of ion concentrations in complex environments.…”

“…Exploiting the specific nucleophilic addition of cyanide ions to distinct electron-deficient double bonds, two additional dithienylethene-based photochromic fluorescent probes for cyanide detection have been developed [ 170 , 171 ]. Several photoswitchable fluorescent probes were synthesized by integrating diarylethene with various structural units possessing active hydrogens, such as hydroxyl and hydrazine groups [ 101 , 172 , 173 ]. Cyanide ions interact with these active hydrogens either by forming hydrogen bonds or by abstracting hydrogen.…”

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.
