In this paper, we present a novel concept for “smarter” photolabile organic compounds combining not one but two caged functions. As proof of principle, this diarylethene-based compound possesses two inhibited chem. groups (OMe and OAc) and its efficient release in different solvents is reported. In low- to medium-polarity media, both MeOH and AcOH are released, with a slight preferential uncaging of AcOH except in 1,4-dioxane, where MeOH is preferentially released. In contrast, DMSO or DMF render AcOH release strongly dominating. DFT calculations of the corresponding photoreactive conformations not only afford strong support to the observed release of MeOH and AcOH but also qual. explain the preferential release of acid in terms of dispersive noncovalent interactions. Finally, mechanistic aspects are discussed on the bases of the spectroscopic observations and of the TD-DFT calculations In the experiment, the researchers used many compounds, for example, Benzo[b]thiophen-3-ylboronic acid (cas: 113893-08-6Synthetic Route of C8H7BO2S).
Benzo[b]thiophen-3-ylboronic acid (cas: 113893-08-6) belongs to benzothiophene derivatives. Benzothiophene finds use in research as a starting material for the synthesis of larger, usually bioactive structures. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.Synthetic Route of C8H7BO2S
