Using polycyclic aromatic hydrocarbons for graphene growth on Cu(111) under ultra-high vacuum. Applied Physics Letters, 121(19), Article 191603. https://doi.org/10.1063/5.0122914

Ultra-high vacuum deposition of the polycyclic aromatic hydrocarbons azupyrene and pyrene onto a Cu(111) surface held at a temperature of 1000 K is herein shown to result in the formation of graphene. The presence of graphene was proven using scannin... Read More about Using polycyclic aromatic hydrocarbons for graphene growth on Cu(111) under ultra-high vacuum.

N-Heterocyclic Carbenes: Molecular Porters of Surface Mounted Ru-Porphyrins (2022)
Journal Article
Knecht, P., Meier, D., Reichert, J., Duncan, D. A., Schwarz, M., Küchle, J. T., Lee, T., Deimel, P. S., Feulner, P., Allegretti, F., Auwärter, W., Médard, G., Seitsonen, A. P., Barth, J. V., & Papageorgiou, A. C. (2022). N-Heterocyclic Carbenes: Molecular Porters of Surface Mounted Ru-Porphyrins. Angewandte Chemie International Edition, 61(49), Article e202211877. https://doi.org/10.1002/anie.202211877

Ru-porphyrins act as convenient pedestals for the assembly of N-heterocyclic carbenes (NHCs) on solid surfaces. Upon deposition of a simple NHC ligand on a close packed Ru-porphyrin monolayer, an extraordinary phenomenon can be observed: Ru-porphyrin...

Silicene, the two-dimensional (2D) allotrope of silicon, is a promising material for electronics. So far, the most direct synthesis strategy has been to grow it epitaxially on metal surfaces; however, the effect of the strong silicon-metal interactio...
