Elucidating the intramolecular contrast in the STM images of 2,4,6-tris(4',4'',4'''-trimethylphenyl)-1,3,5-triazine molecules recorded at room-temperature and at the liquid-solid interface

Star-shaped 2,4,6-tris(4',4'',4'''-trimethylphenyl)-1,3,5-triazine molecules self-assemble at the solid-liquid interface into a compact hexagonal nanoarchitecture on graphite. High resolution scanning tunneling microscopy (STM) images of the molecules reveal intramolecu...

Description
Summary:Star-shaped 2,4,6-tris(4',4'',4'''-trimethylphenyl)-1,3,5-triazine molecules self-assemble at the solid-liquid interface into a compact hexagonal nanoarchitecture on graphite. High resolution scanning tunneling microscopy (STM) images of the molecules reveal intramolecular features. Comparison of the experimental data with calculated molecular charge density contours shows that the molecular features in the STM images correspond to molecular LUMO+2.
