Nondestructive Room-Temperature Adsorption of 2,4,6-tri(2^<i>t</i>-thienyl)-1,3,5-triazine on a Si-B Interface: High-Resolution STM Imaging and Molecular Modeling

Organic nanostructures on semiconductors are currently investigated but the surfaces are known to interact strongly with molecules. To reduce the molecule-surface interaction, we used the Si(111)-B √3 × √3R30°. Deposition of isolated 2,4,6-tri(2^<i>t</i>-thienyl)-1,3,5-triazine, was achieved at room temperature without modification of their π skeleton. This fascinating arrangement, observed by STM, has been validated by full density functional theory computations onto the entire system. The theoretical results give a clear explanation for the specific adsorption sites of molecules on the substrate.
