AI Article Synopsis
- A modular system has been created for attaching molecules in a precise upright position on metal surfaces using a triazatriangulenium salt with an electrophilic center.
- Functional molecules are linked through C-C bond formation, allowing for adjustable distances from the surface and between the functional units based on the platform size.
- The self-assembly of both the parent and functionalized platforms on Au(111) surfaces leads to stable, hexagonally ordered layers.
Article Abstract
A modular system has been developed to mount molecules upright onto metal surfaces in a well controlled geometry. The approach is based on a reactive platform (triazatriangulenium salt) with an electrophilic center. Functional molecules are attached via C-C bond formation. The distance from the surface can be varied by a spacer, and the distance of the functional units from each other by the size of the platform. Self-assembly of the parent triazaangulenium salt as well as the functionalized platforms on Au(111) surfaces results in stable, hexagonally ordered adlayers.
