Abstract:

5-(Benzyloxy)-isophthalic acid (BIC) derivatives and heptanol (HA) molecules adsorb on a highly oriented pyrolytic graphite (HOPG) surface. The surface forms a 2D network structure through weak hydrogen bond interactions. We used molecular dynamics to simulate this adsorption process and perform quantitative analysis of the characteristic parameters, such as the structure geometry, amount of energy, and the number, length and angle of the hydrogen bonds. We compared these results with the experimental result and performed correlational research on the forming tendency and stability between the hydrogen bonds and the chiral selfassembled structure.

Key words: Chiral, Self-assembly, Molecular dynamics, Hydrogen bond
