Controllable mol. self-assembly is vital for nanostructure construction. Here, three different self-assembling networks are realized by varying the chem. composition of the mol. building blocks of the same architecture. This is the first time that S···N electrostatic attraction has been employed to regulate surface self-assembly. All mol. structures are characterized using low-temperature scanning tunnelling microscopy. The d. functional theory calculations elaborate the structure formation mechanism. In the experiment, the researchers used many compounds, for example, 5,8-Dibromoquinoxaline (cas: 148231-12-3Quality Control of 5,8-Dibromoquinoxaline).
5,8-Dibromoquinoxaline (cas: 148231-12-3) belongs to pyrazine derivatives. Pyrazines are part of several biologically active polycyclic compounds; examples are quinoxalines, phenazines; and the bio-luminescent natural products pteridines, flavins, and their derivatives. Pyrazines are chemical compounds (technically called “methoxypyrazines”) found in grape skin and stems that are responsible for many “green” flavors in wine. Levels of pyrazines are dependent on viticultural practices, climate, and grape variety.Quality Control of 5,8-Dibromoquinoxaline
