Exploration into the domain of molecular adsorption on two-dimensional (2D) materials carries significant expectations, offering insights into unprecedented physicochemical phenomena and paving the way for the future development of nanodevices [1,2]. The present work explores the intricacies of the adsorption of the prototypic molecule Perylenetetracarboxylic dianhydride (PTCDA) on single layers of polycrystalline hexagonal boron nitride (h-BN) grown on Pt(111) surfaces, focusing on the structural and electronic properties of adsorbed molecules near domain boundaries. This research has been conducted under ultrahigh vacuum conditions, utilizing a variable temperature scanning tunneling microscope as the main characterization tool.
