COA of Formula: C6H4N2In 2020 ,《Fluorinated carboxylic acids as powerful building blocks for the formation of bimolecular monolayers》 was published in Chemical Communications (Cambridge, United Kingdom). The article was written by Pinfold, Harry; Greenland, Christopher; Pattison, Graham; Costantini, Giovanni. The article contains the following contents:

We compare the ability of a prototypical dicarboxylic acid and its fluorinated analog to act as mol. building blocks for the formation of self-assembled monolayers. While fluorination is found to prevent homomol. self-assembly, it greatly increases the ability of the carboxylic acid to act as a hydrogen bond donor for the formation of bimol. networks. In the experiment, the researchers used 4-Cyanopyridine(cas: 100-48-1COA of Formula: C6H4N2)

4-Cyanopyridine(cas: 100-48-1) belongs to pyridine. Pyridines, quinolines, and isoquinolines have found a function in almost all aspects of organic chemistry.

Furthermore, the bioprobes were capable of monitoring the movements of the LDs in real time. The authors believe that bioprobes would provide new avenues to designing bioimaging and biol. diagnosis.
