The article was titled 《Cyclopentadienone Derivative Dimers as Tunable Photoswitches》.Recommanded Product: Pyridin-3-ylboronic acid The article contains the following contents:
A series of photoswitchable cyclopentadienone derivative dimers bearing bromo, thienyl, 4-(dimethylamino)phenyl, 3-pyridinyl, 4-nitrophenyl and cyano groups was designed and facilely synthesized. Photoswitching properties such as the photoconversions in the photostationary state (PSS), the thermal kinetics and thermal half-lives of photoisomers were systematically studied. These photoswitches show high fatigue resistance and large photoconversions in the PSS. This work proves that the photoswitching properties of photoswitches based on cyclopentadienone dimers can be tuned by substitution groups and also pave the way to functionalize the cyclopentadienone derivative dimer-based photoswitch, which is important for its future applications. The results came from multiple reactions, including the reaction of Pyridin-3-ylboronic acid(cas: 1692-25-7Recommanded Product: Pyridin-3-ylboronic acid)
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Recommanded Product: Pyridin-3-ylboronic acid
