Electrochemical Self-Assembly of π-Conjugated Molecules on Gold Surfaces

Research data investigates the potential-dependent adsorption of two π-conjugated brominated molecules, PPr-4Br and DTPPr-4Br, on Au(111) surfaces. The dataset includes results from in situ electrochemical scanning tunneling microscopy and voltammetry experiments, published by Rajendiran Balasaravanan on figshare in 2026. It provides atomic-scale insight into how molecular design and electrochemical control cooperate to determine interfacial organization.

Use Cases

• Modeling molecule-substrate coupling based on π-conjugated backbone structure mentioned in the description
• Analyzing the effect of electrode potential on molecular mobility and ordering pathways described in the study
• Comparing structural evolution of planar versus thiophene-incorporated molecules under positive polarization
• Training models to predict adlattice formation from electrochemical parameters and molecular geometry

Strengths

• Includes data from in situ electrochemical scanning tunneling microscopy, providing direct atomic-scale observation
• Compares two distinct π-conjugated molecules (PPr-4Br and DTPPr-4Br) under controlled potential windows
• Data is associated with a published scientific study, providing context and validation

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Dataset size is 1.5 MB, indicating a relatively small-scale experimental dataset
