“…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.…”

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.

“…Many DAEs exhibit strong photochromism with high cyclization quantum yields, high thermal stability of the closed isomer, and high fatigue resistance. Originally, DAEs were intended as optical storage media [7,8] but due to their promising photophysical properties, the application interest quickly expanded to fields such as photopharmacology, [9,10] molecular sensors, [11,12] high-resolution microscopy, [13][14][15][16][17][18] and functional organic electronics. [19,20] In 2013 our lab introduced a new class of DAEs in which one of the aryl moieties was replaced by a pyrimidine nucleobase of a nucleoside (Figure 1b) or oligonucleotide.…”

A DNA‐Based Two‐Component Excitonic Switch Utilizing High‐Performance Diarylethenes

Nucleosidic diarylethenes (DAEs) are an emerging class of photochromes but have rarely been used in materials science. Here, we have developed doubly methylated DAEs derived from 2'-deoxyuridine with high thermal stability and fatigue resistance. These new photoswitches not only outperform their predecessors but also rival classical non-nucleosidic DAEs. To demonstrate the utility of these new DAEs, we have designed an all-optical excitonic switch consisting of two oligonucleotides: one strand containing a fluorogenic double-methylated 2'-deoxyuridine as a fluorescence donor and the other a tricyclic cytidine (tC) as acceptor, which together form a highly efficient conditional Förster-Resonance-Energy-Transfer (FRET) pair. The system was operated in liquid and solid phases and showed both strong distance-and orientation-dependent photochromic FRET. The superior ON/OFF contrast was maintained over up to 100 switching cycles, with no detectable fatigue.

“…Photochromic compounds could be switched between two isomers by alternating irradiation with ultraviolet and visible lights, and have been used to construct various reversible fluorescent switching systems [36][37][38]. Among the photochromic compounds, diarylethene (DT) have attracted the attention of many researchers, and be used in the construction of fluorescent switching systems with various organic fluorophores and quantum dot [39][40][41][42]. On the other hand, some works have been carried out on the reversible fluorescence switching systems using CDs.…”

Photo-controlled fluorescent switching is of great utility in fluorescence sensors, reversible data storage, and logic circuit, based on their modifiable emission intensity and spectra. In this work, a novel photo-controlled reversible fluorescent switching system was constructed based on photochromic diarylethene (DT) molecular modified fluorescent carbon dots (CDs). The fluorescent CDs acted as fluorescent donors and the photochromic diarylethene molecular functioned as acceptors in this fluorescent switching system. The fluorescence modulation efficiency of the fluorescent switching was determined to be 97.1%. The result was attributable to Förster resonance energy transfer (FRET) between the CDs and the diarylethene molecular. The fluorescent switching could undergo 20 cycles without significant decay.
