Molecular planting of a single organothiol into a “gap-site” of a 2D patterned adlayer in an electrochemical environment† † Electronic supplementary information (ESI) available. See https://doi.org/10.1039/d1sc07227g

ABSTRACT: The self-assembled inclusion of molecules into two-dimensional (2D) porous networks on surfaces has been extensively studied because 2D functional materials consisting of organic molecules have become an important research topic. However, the isolation of a single molecular thiol remains a challenging goal. Here, we report a method of planting and isolating organothiols onto a 2D patterned organic adlayer at an electrochemical interface. In situ scanning tunneling microscopy revealed that the phase transition of an ovalene adlayer is electrochemically induced and that the gap site created by three ovalene molecules serves as a 2D molecular template to isolate thiol molecules and to standardize the distance between them via the formation of precise selective open spaces, suggesting that electrochemical “molecular planting” opens applications for 2D patterns of isolated single organothiol molecules. Gap sites electrochemically created in the ovalene adlayer can accept a single thiol.
