Photochromic mol.-incorporated optical devices offer desirable properties for photocontrollable optical systems, including advanced optical data storage and super-resolution imaging. However, these mols. require multiple illumination sources, such as UV and visible light, for reversible photochem. reactions, which restricts their potential for advanced application. This study reports an effective strategy for modulating photoisomerization via a single near-IR light source assisted by plasmonically enhanced photoswitchable upconversion photoluminescence (UCPL). The proposed quasi-periodic metal nanostructures to facilitate the resonance modes in the broadband region enable the substitution of the detrimental high-energy light source (i.e., UV light) with near-IR stimuli, which is associated with UCPL enhancement of over two orders with spectrum orthogonality. To validate this concept, the accelerated reversible-photoisomerization kinetics is exptl. confirmed by three- and tenfold amplification of the PL intensities of the photochromic disulfonyldiarylethene derivatives Further validation of the proposed strategy is performed using photodynamic imaging, which reveals accelerated photoisomerization, high photocyclization stability, and high spatial resolution In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Related Products of 10243-15-9).
3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) belongs to benzothiophene derivatives. Benzothiophenes are valuable heterocycles that are widely used in medicines, agrochemicals, and materials science. It is found within the chemical structures of pharmaceutical drugs such as zileuton, raloxifene, and sertaconazole, and also BTCP.Related Products of 10243-15-9
