Potential-Dependent Self-Assembly of π-Conjugated Molecules on Au(111)

Atomic-scale imaging data from an electrochemical study investigates the potential-dependent adsorption of two π-conjugated brominated molecules, PPr-4Br and DTPPr-4Br, on a gold surface. The dataset, authored by Rajendiran Balasaravanan and last updated in May 2026, includes results from in situ electrochemical scanning tunneling microscopy and voltammetry. It demonstrates how electrode potential governs self-assembly through a competition between molecular mobility and substrate pinning.

Use Cases

• Modeling molecular adsorption behavior based on electrode potential and molecular structure.
• Comparing self-assembly pathways of different π-conjugated molecules based on backbone chemistry.
• Investigating the relationship between substrate coupling and long-range order in electrochemical interfaces.

Strengths

• Includes data from in situ electrochemical scanning tunneling microscopy and voltammetry, providing direct atomic-scale insight.
• Compares two distinct π-conjugated molecules (PPr-4Br and DTPPr-4Br) under varying electrochemical conditions.
• Data is associated with a specific scientific publication, providing context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (1.1 MB), which may limit the scope of analysis.
