“…The colloidal aqueous suspension containing nanoparticles of 157 emits appreciable fluorescence (Φ f = 0.017) and undergoes efficient photochromic reactions (Φ o→c = 0.20 and Φ c→o = 0.96). Nanocrystals of compound 156 grown in sol–gel thin film also exhibit fluorescence . A photoswitchable probe 195 was prepared for living cells imaging using an amphiphilic diarylethene, which has both hydrophilic and hydrophobic chains at each end of the diarylethene unit .…”

“…27 Thanks to its multiple merits, DTE derivatives are potential candidates for numerous applications, including data storage, nondestructive readouts, and optical devices. [28][29][30] To date, numerous studies have focused on DTE-based photoswitchable materials, such as polymeric solutions, 31 sol-gels 32 and surfaces, and interfaces. 33 However, DTE-based polymeric solid materials are rare.…”

Photoswitchable polymeric materials are promising candidates for rewritable patterning and optical information storage. However, traditional solid photoswitchable polymers are generally hampered by a low fatigue resistance and slow photoresponse. To overcome these two key deficiencies, in this study, we examined a simple synthetic strategy for producing photoswitchable polyurethane films via the covalent attachment of an excellent photochromic diarylethene. The as‐prepared diarylethene‐based polyurethane (DTE–PU) film showed rapidly reversible isomerization and splendid photoreversibility (>20 times). Additionally, the as‐prepared DTE–PU film in the closed form possessed outstanding thermal irreversibility and long‐term optical stability. Photowritten patterns on the DTE–PU film remained steady for more than 2 weeks. These eminent properties made the DTE–PU film a promising candidate for multifarious applications, including rewritable patterning and stable optical information storage. © 2019 Wiley Periodicals, Inc.

“…Among them, the interesting properties of organic dyes have been utilized in various studies. The dyes with colorful chromophores, such as diarylethenes , and spiropyrans, , have been used as photochromic materials based on their color change due to their structural changes by external light stimulation. In addition, some dyes are expected to be used as functional materials for electroluminescence, laser devices, etc., and some of them are already in use.…”

The thin films consisting of crystalline ZnO particles were prepared on fluorine-doped tin oxide electrodes by electroless deposition. The particles were deposited from an aqueous solution containing zinc nitrate, dimethyamine−borane, and eosin Y at 328 K. As the Pd particles were adsorbed on the substrate, not only the eosin Y monomer but also the dimer and debrominated species were rapidly adsorbed on the spherical ZnO particles, which were aggregated and formed secondary particles. On the other hand, in the absence of the Pd particles, the monomer was adsorbed on the flake-shaped ZnO particles, which vertically grew on the substrate surface and had a high crystallinity. The photoelectric conversion efficiency was higher for the ZnO electrodes containing a higher amount of the monomer during light irradiation.
