The First Detection of a Clar's Hydrocarbon, 2,6,10-Tri-tert-Butyltriangulene:  A Ground-State Triplet of Non-Kekulé Polynuclear Benzenoid Hydrocarbon

Improved All-Carbon Spintronic Device Design

“…The destabilizing effects of topological frustrations and the presence of free radicals on the proposed TZGNF and bow-tie based devices are rarely, if ever, mentioned, despite the well-documented experimental difficulties of isolating such structures2538. However, topological frustration is not a prerequisite for spin ordering, and by careful device design their detrimental effects can be avoided.…”

“…Attempts at synthesis of non-Kekuléan hydrocarbon structures have resulted in unstable structures that decay at ambient conditions, destroying the desired properties at room temperature25 or that oxidize in a few days when exposed to ambient atmosphere26. Stable non-Kekulé structures exist but generally require the introduction of non-carbon atoms2728.…”

Review on graphene spintronic, new land for discovery

“…According to [87] and previous work on vacancies in graphene [98], a single vacancy results in the formation of a local moment with , and the sign of the spin coupling between two single atom vacancies would depend on whether or not they belong to the same sub-lattice [99]. This was confirmed experimentally [100,101] and by first-principles calculations [21,82,89]. However, for the finite graphene nano-flakes calculated by the authors, no spin-polarized state was caused by vacancy(es) [54].…”

Atomic displacements due to spin–spin repulsion in conjugated alternant hydrocarbons

“…It can be interpreted by considering that the carbon sites where certain radicaloid structures exist suffer the largest spin-spin repulsion and so their atomic displacements are relatively large. In the case of the triangulene illustrated in Figure 3 [24]. All these findings indicate that the index pp G is a good indicator of the spin density at sites in GNFs.…”
