Cyclic and linear conjugated small mols. comprising dithienylethene (DTE) and thiophene groups were synthesized via Suzuki and McMurry couplings. The cyclic mol. was polymerized via ring-opening metathesis polymerization (ROMP) using a second-generation Grubbs catalyst to produce a DTE- and thienylene vinylene-containing conjugated polymer. DTE-containing small mols. exhibited (quasi-) reversible photochromism through alternating UV and visible light irradiation The small linear mols. showed faster photochromism than the cyclic mol. In contrast, the linear dimer and polymer did not undergo photochromism; however, they showed efficient photoluminescence, with quantum yields of 0.26 and 0.18, resp.

Li, Jiting published the artcileSynthesis and properties of pyridyl dithienyl ethene axially coordinated to Mn(II)-porphyrin, COA of Formula: C15H14Cl2S2, the publication is Yingyong Huaxue (2017), 34(4), 402-407, database is CAplus.

Organic photochromic materials have bottleneck problems including low photon yield, poor fatigue resistance and destruction of recorded information after read-out in practical application. In this paper the pyridyl dithienyl ethene axially coordinated to Mn(II)-porphyrin was synthesized by 1-(5-chloro-2-methylthien-3-yl)-2-[5-pyridyl-2-methylthien-3-yl] cyclopentene via halogenations, Friedel-Crafts acylation, McMurry coupling and Suzuki coupling by using 2-methyl-thiophene as the starting material coordinating with Mn(II)-porphyrin. Photochromic properties and fatigue resistance of the target compound were investigated by UV-visible (UV-Vis) spectrum, and the function of nondestructive readout was also reached by fluorescence spectrum. The exptl. results indicate that the target compound possesses good photochromic properties and fatigue resistance, and the ”write-read-erase” process can be achieved by using the light of 254 nm, 490 nm, and 550 nm, resp., without concomitant loss of data which is expected to be used in binary storage devices.

A kind of basal diarylethene through an easy synthetic procedure was synthesized and characterized, and a Suzuki coupling reaction was frequently operated to obtain the diarylethenes derivatives with some vivid functional groups like bromo, amido and pyridine. Two methods for derivatives of these switches contain porphyrins were described. All of their spectroscopic and photochromic properties were studied and intercompared. It is indicated that the difference in electron densities of the π-conjugated system of the closed forms has effects upon the absorption maxima in visible region of UV-Vis spectra. Dithienylcyclopentenes linked to porphyrins could emit luminescence substantially that display potentials to be used in the applications of nondestructive readout upon binary data storage and smart materials.

Their structures have been reliably confirmed by NMR, ESI-MS or MALDI-QTOF-MS, and elemental anal., and their energy-minimized structures of open- and closed-ring isomers were investigated by the theor. calculation Investigation of the photochromic properties of these dithienylethene-based [2]catenanes has revealed good reversibility and excellent fatigue resistance upon irradiation with UV or visible light. Notably, formation of the [2]catenanes enhanced the photochromic properties compared with those of the corresponding macrocyclic ammonium salt, implying that the non-covalently interacting components of the [2]catenanes could affect the photoswitchable properties.

Bis(imino nitroxide) bridged by a diarylethene annulated isomer was synthesized and the exchange interaction between the two radicals was determined by the simulation of the ESR spectrum. The exchange interaction was found to be as large as that of the closed-ring isomer, suggesting that the annulated isomer can be used as a highly-conductive mol. wire in mol. electronics.

Chai, Xianzhi published the artcileTargeted photoswitchable imaging of intracellular glutathione by a photochromic glycosheet sensor, Related Products of chlorides-buliding-blocks, the publication is Beilstein Journal of Organic Chemistry (2019), 2380-2389, database is CAplus and MEDLINE.

The development of photochromic fluorescence sensors with dynamic and multiple-signaling is beneficial to the improvement of biosensing/imaging precision. However, elaborate designs with complicated mol. structures are always required to integrate these functions into one mol. By taking advantages of both redox-active/high loading features of two-dimensional (2D) manganese dioxide (MnO₂) and dynamic fluorescence photoswitching of photochromic sensors, we here design a hybrid photochromic MnO₂ glycosheet (Glyco-DTE@MnO₂) to achieve the photoswitchable imaging of intracellular glutathione (GSH). The photochromic glycosheet manifests significantly turn-on fluorescence and dynamic ON/OFF fluorescence signals in response to GSH, which makes it favorable for intracellular GSH double-check in targeted human hepatoma cell line (HepG2) through the recognition between β-D-galactoside and asialoglycoprotein receptor (ASGPr) on cell membranes. The dynamic fluorescence signals and excellent selectivity for detection and imaging of GSH ensure the precise determination of cell states, promoting its potential applications in future disease diagnosis and therapy.

Mech. interlocked structures such as rotaxanes and catenanes provide a novel backbone for constructing functional materials with unique structural characteristics. In this study, we have designed and synthesized a series of photoswitchable rotaxanes and catenanes containing photochromic dithienylethene fragments using a template-directed clipping approach based on dynamic imine chem. Their structures have been confirmed using NMR, mass spectrometry and elemental anal. Investigations into their photoisomerization properties indicated that these dithienylethene-based mech. interlocked mols. have good reversibility and excellent fatigue resistance upon irradiation with UV or visible light. Interestingly, the mech. interlocked mols. containing two dithienylethene backbones display around a 2-fold increase in the molar absorption coefficient compared with that of the mono dithienylethene derivative Furthermore, the introduction of the fluorophore pyrene in the dithienylethene component facilitates these mols. to serve as fluorescent switches.

Sanchez, Rafael S. published the artcileLight- and Redox-Controlled Fluorescent Switch Based on a Perylenediimide-Dithienylethene Dyad, Synthetic Route of 219537-97-0, the publication is Journal of Physical Chemistry C (2012), 116(12), 7164-7172, database is CAplus.

The development of luminescent materials that are sensitive to both optical and elec. stimuli is of high interest for the fabrication of future information-processing devices. In this study we report about a novel fluorescent mol. switch (1) that can be light- and redox-controlled. This compound has been synthesized by covalent tethering of a perylenediimide fluorophore (PDI) to a dithienylethene (DTE) unit. The photochromic properties of the DTE group are preserved in the dyad, which can be reversibly converted between open (1o) and closed (1c) states upon irradiation In addition, 1 displays electrochromicity, and its ring-opening process can be promoted quant. by electrochem. oxidation Whereas the open-ring state of the switch is highly fluorescent, the emission of the PDI group in 1c is quenched by energy transfer to the DTE group. This allows large fluorescence modulation between the two states of 1, which can be operated either as an all-optical switch or by a combination of photo- and electrochem. stimuli.
