Volume 12 Issue 4, April 2017

Triangulene is a triangular segment of graphene, but any attempt to draw alternating single and double bonds for the whole molecule leaves two electrons unpaired. Those two electrons make this molecule extremely reactive and challenging to isolate. Now, Niko Pavliček and co-workers have overcome the difficulties by using atomic manipulation techniques and succeeded in synthesizing triangulene on various surfaces. The cover shows a pattern realized with an atomic force microscope image of a single triangulene molecule.
