Scientists finally synthesized Triangulene Molecule after 67 years

  • Triangulene is a triangle shaped molecule synthesized by scientists in IBM laboratory.
  • Triangulene has magnetic properties and it is a reactive molecule and is related to Graphene.
  • It was 1950 when first time hypothesis of a triangle shaped molecule was proposed.

The researchers had been trying to make triangle shaped  molecule for a very long time that is about 67 years. But looks like 2017 has been good for science and researchers as scientists finally created Triangulene that is an unstable molecules with so many unpredictable properties. This a strange molecule which was always considered  impossible to be synthesized but scientist have finally made it.triangulene bond length


Triangulene is made up of carbon atoms that have 4 electrons in its outermost shell. According to Huckel’s Rule Triangulene has all the aromatic molecules’s property. Triangulene has 22 pie electrons, it is cyclic and is planar. Whenever you try to create any resonance structure of the Triangulene now matter how hard researcher try there will always be two unpaired electron because carbon can not form five bonds to put the double bonds in the middle ring. It is actually made bye joining of six hexagonal carbon molecule by their edges forming a triangular structure which is only on carbon atom thicker than normal Grephene.

The Triangulene molecule is created by IBM’s research team by altering the position of atoms to desired places using a microscope tip that looks like needle. It was very difficult for researchers to synthesize Triangulene because it was very unstable and scientist had to work very hard to verify its existence, but finally scientists stabilized it so that its existence could be verified.

A 67 years old hypothesis

Erich Clar in 1950 proposed a hypothesis about Triangulene molecule. It was always considered impossible . According to Erich Clar — hypothetically at any rate — a triangle-molded hydrocarbon could be produced using six combined roundabout benzene particles that would have a considerably number of iotas and electrons, however would leave two unpaired electrons because of its plan.Triangulene diagram

Clar attempted and neglected to make Triangulene in the lab. It’s a staggeringly troublesome errand, in light of the fact that those two unpaired electrons don’t care to stay unpaired, so promptly respond with anything around them.Ordinary amalgamation procedures include researchers responding atoms together to develop bigger structures. Be that as it may, for just about 70 years, analysts have attempted to make Triangulene along these lines.”When you blend it, it will oxidize,” said one of the analysts, Niko Pavliček.

The IBM group conquered this by utilizing an alternate system — as opposed to working up a structure atom by particle, they initially made a bigger antecedent structure and after that whittled it down.The forerunner had two or three additional hydrogen iotas on it to make the particle was steady. These hydrogen iotas were launched utilizing an electron shaft, leaving the insecure Triangulene particle.They were even ready to picture the structure utilizing an examining test magnifying instrument.

What can be applications of Triangulene ?

  • This can be used in our computer, mobiles and other electronic devices as batteries they can give a backup of many days after charging for seconds.
