Exploring Molecular Patterns: Insights from Phenyl-TOTA on Gold Surfaces

Each dot in these vibrant green patterns represents a molecule resting on a gold substrate. More specifically, these are phenyl-functionalized trioxatriangulenium (phenyl-TOTA) molecules, characterized by a phenyl ring extending from a base shaped like an inverted bowl.

Molecular Patterns on Gold

The meticulous observations revealed that the molecules fit seamlessly into the grooves of the gold’s crystalline structure, showcasing hexagonal and linear arrangements.

Investigating Phenyl Ring Rotation

The researchers aimed to explore whether rotating the phenyl ring on one phenyl-TOTA could influence the rotation of a neighboring molecule. Thanks to the high resolution of their STM, they were able to focus on individual molecules, discovering that under specific conditions, each single-molecule dot appeared to split into two distinct dots.

This phenomenon was ultimately linked to the alignment of each phenyl ring, providing fascinating insights into molecular interactions.
