Condensed-ring aryl compound, organic electronic device, and application thereof

The invention provides a condensed-ring aryl compound, an organic electronic device, and an application thereof. The compound has the structure represented as the formula (I) or (II), wherein X1, X2 and Y1 are independently selected from a combination of a connecting bond, N and CR6, the ring A and the ring B are in a conjugated structure, any one of the R1 to R4 and the R6 are independently connected to the ring A the ring B via a single bond or a double bond, and/or the any adjacent two among the R1 to R4 and the R6 form a ring C, being an electron-withdrawing ring, the R5 is selected from aconnection bond, R7-substituted or -non-substituted C6-C30 aryl groups, and R7-substituted or -non-substituted C2-C30 heteroaryl groups, and the R1 to R4, R6 and R7 are electron-withdrawing groups. The compound is free of intramolecular stacking and can prolong service life of the device, wherein the substituent groups are electron-withdrawing groups, and the compound has LUMO energy level of -4.6 to -6.0 eV. The compound can serve as a P-doping material.

Mechanistic Studies on the Electrochemical Reductive Coupling of some Polyhalogenonitrobenzenes. A New Example of a Radical Anion Dimerization

Coupling processes with loss of one halogen atom per ring are observed when heavily substituted polyhalogenonitrobenzenes (polyfluoro- and polychloro-) are electrochemically reduced in DMF.Product analyses and cyclic voltametry mechanistic studies suggest that in the particular case of pentafluoronitrobenzene, direct dimerization of the radical anions occurs prior to C-F bond fragmentation.On the contrary, reduction of the nitro group is the only observed process when less substituted polyhalogenonitrobenzenes are used in the same conditions.Nitro group reduction is also the main process for all the studied polyhalogenonitrobenzenes when the reactions are carried out in protic solvents. - Keywords: Reductive Coupling, Radical Anions, Fluoronitroaromatics, Dimerization
