Abstract

Molecular architectures (Kagome networks, coordinated/covalent dimers and branched coordination chains) via self-assembly, Ullmann reaction and pyridine coordination of 4-[(4-bromophenyl)ethynyl]pyridine are found to be sensitive to the underlying metallic surfaces. The molecular species were characterised on the surface by low-temperature scanning tunnelling microscopy (LT-STM) at sub-molecular level.
