  The growth and assembly of aminobenzoate (NH<sub>2</sub>C<sub>6</sub>H<sub>4</sub>COO<sup>-</sup>) isomers (<i>ortho</i>, <i>meta</i> and <i>para</i>) on Cu(110) have been investigated with a scanning tunneling microscope (STM) at 4.7 K. At the initial stage, well-ordered islands of (4×3) and (3×4) superstructures are formed for <i>ortho</i>- and <i>para</i>-aminobenzoate layers, respectively. The growth of <i>ortho</i>- and <i>para</i>-aminobenzoate layers were found to proceed in different manner from each other, which is responsible for the intermolecular interaction through the hydrogen bonding. In the case of <i>meta</i>-aminobenzoate, short-ranged (6×4) superstructures were observed. Our STM study clearly demonstrates that the substituent position on the aminobenzoate affects not only the superstructure patterns but also their growth process. We suggest that the hydrogen bonding plays a key role in the molecular linkage, being controlled by positioning of the substituents.<br>
