- DIINDENOPERYLENE DIANION. LOCAL vs. PERIPHERAL CONTRIBUTIONS TO THE AROMATIC CHARACTER
-
Diindenoperylene (1) is shown to undergo a two electron reduction process to its dianion 2.Both neutral and doubly charged systems exhibit an enhanced diamagnetic character which is belived to be acquired via two different mechanisms.

- Electronic structure of diindenoperylene radical anion
-
The electronic structure of diindenoperylene (periflanthene) radical anion has been studied on the basis of the ESR, electronic absorption, and linear dichroism spectra.The observed results are interpreted in terms of the SCF MO calculations within the framework of the ?-electron approximation.

- A two-[...] synthetic method
-
The invention discloses a method for synthesizing periflanthene. The method comprises the following steps that fluoranthene, sodamide and organic solvent are added to a reaction container, inert gas is charged into the reaction container, then heating is carried out to carry out a synthetic reaction, and a mixed solution of the periflanthene is obtained; after the mixed solution with the periflanthene is cooled, absolute ethyl alcohol is dropwise added, then water is dropwise added, and periflanthene crude products are obtained through filtering. Compared with the prior art, the method has the advantages that reaction path raw materials can be obtained easily, cost is low, the yield is high, the technological requirement is low, operation is easy, the reaction process and aftertreatment are safe, purification is easy, and industrial production is facilitated.
