Organoboron-functionalized 1,2-dithienylcyclopentene [1-(5-chloro-2-methylthien-3-yl)-2-[5-(dimesitylboryl)-2-methylthien-3-yl]cyclopentene] was prepared, characterized by x-ray crystallog., et al. and found to show photochromism (via photocyclization). Its absorption spectra can be modulated by fluoride and mercuric ions. The maximum of the photostationary state shifts from 560 to 490 nm upon the addition of fluoride anions and to 450 nm upon the addition of mercuric cations. The modulation mechanism was studied.

A series of novel, functional sym. and unsym. photochromic thiophene oligomers based on bisthienylethenes (BTEs) were synthesized via control of the reaction condition with a Suzuki coupling method. Their optical, photochromic quantum yields, two-photon and electrochem. properties in THF as well as in poly(Me methacrylate) (PMMA) films were measured and discussed. The fluorescence emission can be tuned reversibly by alternating irradiation with UV and visible light. These BTEs could be used as nanowires, fluorescent switch and electrochem. switch.

We previously developed a dithienylcyclopentene dopant that bears two methylenedioxy-bridged binaphthyl moieties. Herein, we report our new findings on related compounds that entail different bridge lengths in their binaphthyl units. Three new compounds were synthesized. It was found that variations of the bridge length resulted in significantly different photoresponsive properties in LC media.

Zhou, Zhiguo published the artcileModulation of the Photochromic Property in an Organoboron-Based Diarylethene by a Fluoride Ion, Category: chlorides-buliding-blocks, the publication is Organic Letters (2006), 8(18), 3911-3914, database is CAplus and MEDLINE.

Organoboron-based diarylethene was successfully synthesized and exhibited photochromic property. Furthermore, its photochromic property can be modulated by a fluoride ion. The absorption maximum of the photostationary state shifted from 655 to 490 nm upon addition of a fluoride ion. The modulation mechanism is attributed to the special Lewis acid-base interaction between a trivalent boron atom and a fluoride ion.

Li, Wenjie published the artcileTriptycene-based porous polymers regulated by diarylethenes, Related Products of chlorides-buliding-blocks, the publication is Dyes and Pigments (2018), 72-76, database is CAplus.

Linear and star triptycene-based porous polymers regulated by diarylethenes were constructed via Pd (0)-catalyzed Suzuki coupling reaction, resp. Both triptycene-based porous polymers performed reversible photochromism in solid state but exhibited distinctive solvent-dependent photochromism in solution Their surface area and porous properties were further analyzed by nitrogen sorption isotherms. Results showed that the sp. surface areas and total pore volumes of the two polymers can be reversibly tuned by adjusting the open- and the closed-ring of diarylethene upon irradiating with UV and visible light. These distinctive properties have potential applications in the photo-switched gas adsorption and the probe of chloride solvents.

A novel photo-switchable polymer P-PHT containing diarylethene (DAE) and tetraphenylethene (TPE) moieties and a triazole linker in the repeating unit was synthesized to study the aggregation-induced emission (AIE) behavior of TPE with both the open and closed forms of DAE in P-PHT with high water contents. The photo-switching phenomena of DAE (from open to closed forms under UV-irradiation) in P-PHT were prominent in organic solvent (THF), high water contents (at 90% H₂O) and acidic conditions. Upon UV-irradiation of P-PHT at 90% water content, the AIE of TPE was completely quenched via an energy transfer event from TPE to cyclized DAE. Interestingly, the rare monomeric emission of TPE was first discovered by the photo-cyclization of DAE in P-PHT compared with the AIE behavior of TPE with the open form of DAE in P-PHT with AIE favorable conditions of high water content (90% H₂O) and acidic conditions.

Owing to the compact size, immunity to electromagnetic interference, high sensitivity and real-time monitoring, optical waveguide sensors based on a refractive index change have become an emerging approach for smart sensing in the internet-of-things system. For this purpose, the synergetic efforts in material engineering (sensing materials) and optical engineering (waveguide design and fabrication) are both indispensable. Here we report a Mach-Zehnder interferometer (MZI) waveguide with photochromic dye-doped polymer sensing films for UV light detection. Firstly, UV light induced photochromism of a synthesized dye DAECHO in solution and in the solid state is investigated to understand the relationship between their structure and optical properties, especially the photochromism-induced refractive index change for waveguide sensors. Then the MZI structure is designed and simulated to optimize the performance of refractive index sensing. Following the standard microfabrication process of double photolithog.-development, the device is fabricated with a DAECHO doped polymer as a sensing cladding material for UV light detection. The evanescent sensing of MZI is performed to detect weak UV light from 10 μW cm^-2 to 100 μW cm^-2 at 365 nm. Our demonstration of MZI for UV light detection indicates the potential of portable and highly sensitive UV light waveguide sensors for real-life applications.

Li, Bin published the artcileGold(I)-Coordination Triggered Multistep and Multiple Photochromic Reactions in Multi-Dithienylethene (DTE) Systems, Computed Properties of 219537-97-0, the publication is Inorganic Chemistry (2012), 51(3), 1933-1942, database is CAplus and MEDLINE.

The preparation, characterization, and photochromic properties of a mononuclear Au(I) complex (100) with two identical DTE-acetylides and a dinuclear Au(I) complex (2000) with both DTE-acetylide and DTE-diphosphine are described. Both Au(I) complexes exhibit multistep and multiple photocyclization/cycloreversion reactions. Particularly, four-state and four-color photochromic switch is successfully achieved for the dinuclear Au(I) complex upon irradiation with appropriate wavelengths of light. In contrast, fully ring-closed form is unattained through multiple photocyclization for the two corresponding model organic compounds coupling with the same DTE units as Au(I) complexes but without Au(I)-participation. It is demonstrated that coordination of Au(I) ion to DTE-acetylides exerts indeed a crucial role in achieving stepwise and selective photocyclization and cycloreversion reactions for both Au(I) complexes, in which the coordinated Au(I) atom acts as an effective “barrier” to prohibit intramol. energy transfer between multi-DTE moieties.
