In 2019,ChemPhysChem included an article by Urner, Leonhard H.; Schade, Boris; Schulze, Maiko; Folmert, Kristin; Haag, Rainer; Pagel, Kevin. Electric Literature of C4H7BrO2. The article was titled 《Switchable Solubility of Azobenzene-Based Bolaamphiphiles》. The information in the text is summarized as follows:
The ability to design amphiphiles with predictable solubility properties is of everlasting interest in supramol. chem. Relevant structural parameters include the hydrophobic-hydrophilic balance and structural flexibility. In this work, we investigate the water solubility of azobenzene-based triglycerol bolaamphiphiles (TGBAs). In particular, we analyzed the structural effects of backbone hydrophobicity, flexibility, and cis/trans isomerization on the water solubility of a subset of five TGBAs. This leads to the first example of a non-ionic bolaamphiphile whose water solubility can be changed by irradiation with light. The underlying kinetics were monitored using liquid chromatog. and a closer anal. of the underlying aggregation processes provides a mechanistic understanding of the light-driven dissolution process. We anticipate that the results obtained will help to engineer bolaamphiphiles with predictable solution properties in the future. In addition to this study using 4-Bromobutanoic acid, there are many other studies that have used 4-Bromobutanoic acid(cas: 2623-87-2Electric Literature of C4H7BrO2) was used in this study.
4-Bromobutanoic acid(cas: 2623-87-2) belongs to carboxylic acids. The chief chemical characteristic of the carboxylic acids is their acidity. They are generally more acidic than other organic compounds containing hydroxyl groups but are generally weaker than the familiar mineral acids (e.g., hydrochloric acid, HCl, sulfuric acid, H2SO4, etc.).Electric Literature of C4H7BrO2
