Compound, organic light-emitting device, and electronic device
The invention belongs to the technical field of organic materials, and provides a compound with a structure as shown in a chemical formula 1 which is described in the specification. In the chemical formula 1, Ar1, Ar2, Ar3 and Ar4 are H or a group as shown in a chemical formula 1-1, and at least one of Ar1, Ar2, Ar3 and Ar4 is the group as shown in the chemical formula 1-1. As the molecular structure of the compound contains a triarylamine group, and contains an electron-donating triphenylamine part and a molecular large conjugated system, the molecule of the compound has the property of intramolecular charge transfer. An organic light-emitting device prepared from the compound has high device efficiency. Compared with the prior art, an organic electroluminescent material disclosed by theinvention has higher stability, so the service life of an organic electroluminescent device is prolonged. In addition, a phenanthrene fused ring derivative is used for structural modification of an electron donor and an electron acceptor respectively, so the photophysical and electrochemical properties of the material can be effectively regulated and controlled, and a luminescent layer material with a narrow energy level band gap is obtained. The invention further provides the organic light-emitting device and an electronic device.

Novel Burgess reagent mediated C-to-N aryl migration reaction in nitrones
Nitrones undergo useful transformations with Burgess reagent. The reaction ostensibly involves a [3 + 2] annulation across a σ-bond followed by rearrangement involving C-to-N aryl migration. On the basis of available experimental evidence, plausible mechanisms for the rearrangement and the overall conversion have been proposed.

Bifunctional organic materials for OLEDs based on Tr?ger's base: Subtle structural changes and significant differences in electroluminescence
Three bifunctional organic materials based on Tr?ger's base (TB) scaffold have been designed, synthesized and their functional utility in OLEDs demonstrated through fabrication of devices. The diarylamino-functionalized TBs, i.e., A-TB, PA-TB and P-TB, are all amorphous with considerably high Tgs and permit modulation of electroluminescence with variation of one of the N-aryl rings, e.g., anthryl to 10-phenylanthryl to pyrenyl. Subtle structural modifications are found to manifest in rare pure yellow EL emission from PA-TB.

Synthesis of OLED materials of several triarylamines by palladium catalysts and their light emitting property
Primary aryl amines reacted with aryl halides to give the secondary aryl amines by the catalysis of [Pd(dba)2/P (t-Bu)3] at 80°C in toluene. Secondary aryl amines reacted with 1-bromo-pyrene and 9-bromo-phenanthrene and 2,7-dibromo-9H-fluorene to afford the OLED material of aminopyrene derivatives and aminophenanthrene derivatives and diamino-9H-fluorene type by the catalysis of [Pd(OAc)2/P(t-Bu) 3] at 120°C in o-xylene. The product structures were established by 1H NMR, 13C NMR, 13C(DEPT), HRMS spectra. Physical properties were examined by UV-vis, PL and DSC spectra.
