“…The ratiometric approach helps to eliminate variations caused by environmental changes, thereby stabilizing the detection process across different conditions. Following this, Guo et al reported on a photoluminescent probe based on a cyclometalated iridium(III) complex specifically designed for selective detection of thiophenol [ 220 ]. The probe molecule incorporates two photochromic diarylethene (DTE) units and a 2,4-dinitrobenzenesulfonyl (DNBS) group.…”

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.

“…Hence, it is necessary to explore luminescent probes with much longer emission wavelengths. Some types of luminescent probes based on the emission mechanisms of Förster resonance energy transfer (FRET), 8,9 photoinduced electron transfer (PET), 10,11 intramolecular charge transfer (ICT) 12,13 and excited-state intramolecular proton transfer (ESIPT), 14 have been widely explored to detect environmental and biological species. The optical signal detection method exhibits the advantages of small sample consumption, convenient and rapid operation, and high sensitivity and accuracy.…”

“…[26][27][28][29][30][31][32][33][34][35] A convenient approach to prepare photochromic fluorescent switches is to combine DAEs with an energy-level matched fluorophore. [36][37][38][39][40][41] The construction methods of DAE-based fluorescence switches are mainly divided into two categories: covalent binding and noncovalent assembly. We consider that the non-covalent assembly has the following advantages over the covalent binding: (1) the choice of fluorophore becomes larger.…”
