The authors report three self-assembled iron complexes that comprised an anti-parallel open form (o-L-anti), a parallel open form (o-L-syn), and a closed form (c-L) of diarylethene conformers. Under kinetic control, Fe^II₂(o-L-anti)₃ was isolated, which exhibited a dinuclear structure with diamagnetic properties. Under light-irradiation control, Fe^II₂(c-L)₃ was prepared and exhibited paramagnetism and spin-crossover behavior. Under thermodn. control and in the presence of indispensable [Fe^III(Tp^*)(CN)₃]^–, Fe^II₂(o-L-anti)₃ and Fe^II₂(c-L)₃ transformed into tetranuclear Fe^III₂Fe^II₂(o-L-syn)₂, which exhibited complete spin-crossover behavior at T_1/2 = 353 K.

Li, Ziyong published the artcileA Photoswitchable Triple Chemosensor for Cyanide Anion Based on Dicyanovinyl-Functionalized Dithienylethene, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is European Journal of Organic Chemistry (2019), 2019(22), 3614-3621, database is CAplus.

The development of new sensors for the accurate detection of cyanide anion has attracted more and more attention due to their potential applications in environmental and biol. systems. Here, two novel near-IR (NIR) photochromic compounds 1a and 1b, which were modified by the dicyanovinyl fragment with cyanide recognition function, were developed. Surprisingly, 1a presented an unprecedented triple sensing performance for cyanide anion (colorimetric-fluorescent-colorimetric), which can be used as a potential precision sensor for CN^– in environmental and biol. systems. Although 1b did not show triple detection behavior for CN^–, it could recognize CN^– and F^– synchronously and selectively by naked eyes. Also, their NIR photochromic behaviors could be modulated by the cyanide anion. Their sensing mechanism for CN^– or F^– was confirmed by absorption spectral studies, NMR titration, and DFT calculations

Maximo, Patricia published the artcilePhotomodulation of ultrastable host-guest complexes in water and their application in light-controlled steroid release, Synthetic Route of 219537-97-0, the publication is Organic Chemistry Frontiers (2022), 9(16), 4238-4249, database is CAplus.

The cucurbit[8]uril (CB8) synthetic receptor was shown to form high-affinity host-guest complexes with dicationic dithienylethene (DTE) photoswitches I [R = H, Me; R¹ = 1-iodo-1-methyl-2-pyridyl, 1-iodo-1-methyl-3-pyridyl, 1-iodo-1-methyl-4-pyridyl] in water. ITC experiments combined with computational studies suggest that the formation of the inclusion complexes was mainly driven by a combination of hydrophobic effects, ion-dipole, hydrogen- and chalcogen-bonding interactions. The binding affinities were observed to be much higher for the DTE closed isomers, reaching values in the picomolar range (up to 10¹¹ M^-1) while the open isomers display up to 10 000-fold lower affinities, setting ideal conditions for the development of robust photoswitchable host-guest complexes. The light-responsive affinity of these photoswitches toward CB8 was explored to control the encapsulation and release of nanomolar affinity steroids via competitive guest replacement.

Shi, Maohu published the artcileSynthesis and spectroscopic properties of photochromic dithienylethene-functionalized subphthalocyanine conjugate, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Journal of Porphyrins and Phthalocyanines (2016), 20(8/11), 1082-1089, database is CAplus.

A subphthalocyanine-dithienylethene dyad has been synthesized and characterized by ¹H-, ¹³C-NMR, HR-MS, UV-visible and emission spectroscopy. The results show that photoinduced isomerization of dithienylethene moiety from close-form to opened form can be achieved under visible light using subphthalocyanine as a light-harvesting unit and the fluorescence properties of subphthalocyanine could be modulated by the isomerization state of the dithienylethene moiety.

Morant-Giner, Marc published the artcileFunctionalisation of MoS₂ 2D layers with diarylethene molecules, COA of Formula: C15H14Cl2S2, the publication is Journal of Materials Chemistry C: Materials for Optical and Electronic Devices (2021), 9(33), 10975-10984, database is CAplus.

Functionalisation of two-dimensional (2D) materials with stimuli-responsive mols. has been scarcely investigated. Here, MoS₂ layers obtained by chem. exfoliation are covalently and non-covalently functionalised using two photoswitchable diarylethene derivatives under their open- and closed-ring isomers. The choice of these light-responsive mols. is based on their excellent thermal irreversibility and fatigue resistance. The characterization of the resultant mol./2D heterostructures proves the successful anchoring of the mols. by both approaches as well as the influence that the driving interaction has on the photoswitching behavior of the diarylethene isomers after their deposition on the 2D layer.

Boyer, John-Christopher published the artcilePhotomodulation of Fluorescent Upconverting Nanoparticle Markers in Live Organisms by Using Molecular Switches, Computed Properties of 219537-97-0, the publication is Chemistry – A European Journal (2012), 18(11), 3122-3126, S3122/1-S3122/17, database is CAplus and MEDLINE.

It is successfully demonstrated that the ability to modulate the luminescence from upconverting nanoparticles in vitro and in vivo by taking advantage of the well-understood photochem. of DTE mol. switches decorated onto nanoparticle surfaces by the use of CuACC chem. By reversibly converting the photoswitch back and forth between the two isomers by using UV and visible light, we are able to toggle the system between on (bright fluorescence) and off (quenched fluorescence) states. This process can be cycled multiple times before any degradation of the nanoparticles or the photo-switch renders the system impractical. The system has an advantage over ‘caged’ fluorophores as the luminescence of our designed nanoparticles can be repeatedly cycled through on and off states. Systems such as the one described not only have the capacity to reversibly control the intensity of the probe emission, through selective absorption, they can also alter the color of the emitted light from multicolored probes; this further enhances the imaging capabilities.

Warford, C. Chad published the artcileFrom slow to fast – the user controls the rate of the release of molecules from masked forms using a photoswitch and different types of light, Application In Synthesis of 219537-97-0, the publication is Chemical Communications (Cambridge, United Kingdom) (2015), 51(32), 7039-7042, database is CAplus and MEDLINE.

Exposure to UV light generates a ring-closed isomer of a diarylethene, which undergoes very slow bond breaking and release even after the light is turned off. The rate of release is increased by exposing the isomer to UV and/or visible light.

Two stable core-modified rubyrins I and II bearing one and two dithienylethene (DTE) units were synthesized. With one “closed-form” DTE unit, I shows aromaticity associated with its conjugated circuit of 26 π-electrons. In contrast, II containing one “open-form” DTE unit has non-aromatic properties.

Zhai, Yan published the artcilePhotoswitchable micelles for the control of singlet-oxygen generation in photodynamic therapies, SDS of cas: 219537-97-0, the publication is Biomacromolecules (2018), 19(6), 2023-2033, database is CAplus and MEDLINE.

Inadvertent photosensitizer-activation and singlet-oxygen generation hampers clin. application of photodynamic therapies of superficial tumors or s.c. infections. Therefore, a reversible photoswitchable system was designed in micellar nanocarriers using ZnTPP as a photosensitizer and BDTE as a photoswitch. Singlet-oxygen generation upon irradiation did not occur in closed-switch micelles with ZnTPP/BDTE feeding ratios >1:10. Deliberate switch closure/opening within 65-80 min was possible through thin layers of porcine tissue in vitro, increasing for thicker layers. Inadvertent opening of the switch by simulated daylight, took several tens of hours. Creating deliberate cell damage and prevention of inadvertent damage in vitro and in mice could be done at lower ZnTPP/BDTE feeding ratios (1:5) in open-switch micelles and at higher irradiation intensities than inferred from chem. clues to generate singlet-oxygen. The reduction of inadvertent photosensitizer activation in micellar nanocarriers, while maintaining the ability to kill tumor cells and infectious bacteria established here, brings photodynamic therapies closer to clin. application.
