Research highlight

This research presents the adsorption behavior of various molecular complexes, including phthalocyanine and Pd pincer complexes, on metal surfaces such as Cu(100) and Cu(111), and gold (Au(111)). Utilizing a low-temperature, high-magnetic scanning tunneling microscope, we analyze molecular growth dynamics and interactions at temperatures ranging from room temperature to 4 K. Findings from this study contribute to understanding two-dimensional molecular organization and self-ordering mechanisms on conductive substrates, with implications for nanotechnology and materials science.
