Charge transport properties in single-walled carbon nanotubes (SWCNTs) can be significantly modified through doping, tuning their elec. and thermoelec. properties. In our study, we used more than 40 nitrogen-bearing compounds as dopants and determined their impact on the material’s elec. conductivity The application of nitrogen compounds of diverse structures and electronic configurations enabled us to determine how the dopant nature affects the SWCNTs. The results reveal that the impact of these dopants can often be anticipated by considering their Hammett’s constants and pKa values. Furthermore, the empirical observations supported by first-principles calculations indicate that the doping level can be tuned not only by changing the type and the concentration of dopants but also by varying the orientation of nitrogen compounds around SWCNTs. In the experiment, the researchers used many compounds, for example, Pyridin-4-ol (cas: 626-64-2Safety of Pyridin-4-ol).
Pyridin-4-ol (cas: 626-64-2) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Safety of Pyridin-4-ol
