Self-Assemblies of Carboxylic Acid Derivatives with Different Symmetry: Adjusting by Solvent and Guest Molecules
In this research, the self-assembly behaviors of two different symmetry carboxylic acid derivatives (<b>H</b><sub><b>3</b></sub><b>BTE</b> and <b>H</b><sub><b>4</b></sub><b>BTE</b>) regulated by solvent and guest molecule (coronene, COR) were explored at the liquid/solid interface by scanning tunneling microscopy, and the formation mechanism was investigated by density functional theory. In 1-phenyloctane, only <b>H</b><sub><b>3</b></sub><b>BTE</b> molecules dissolved with extremely low concentration and self-assembled into a honeycomb structure and a new strip structure, while <b>H</b><sub><b>4</b></sub><b>BTE</b> could not. In 1-heptanoic acid, <b>H</b><sub><b>3</b></sub><b>BTE</b> and <b>H</b><sub><b>4</b></sub><b>BTE</b> were easily dissolved, in which <b>H</b><sub><b>3</b></sub><b>BTE</b> formed a regular row structure and <b>H</b><sub><b>4</b></sub><b>BTE</b> formed a tetragonal structure, respectively. The host-guest interaction was investigated by introducing the COR molecules into their self-assembly structures, and due to the different symmetry, <b>H</b><sub><b>3</b></sub><b>BTE</b> and <b>H</b><sub><b>4</b></sub><b>BTE</b> displayed different accommodation behavior.
