Triangulene-based Nanostar
A star-shaped triangulene cyclic hexamer, which accumulates 12 unpaired electrons, was prepared by combining solution chemistry and on-surface synthesis. The resulting triangulene-based nanostar was visualized by bond-resolved scanning tunneling microscopy on a gold substrate. The particular magnetic ordering of the 12 unpaired electrons gives rise to collective spin excitations.
