Compound, organic electroluminescent device and electronic device

The invention belongs to the technical field of OLEDs and provides a compound with a structure of a chemical formula 1, wherein X1, X2 and X3 are C or N, and at least one of X1, X2 and X3 is N; X4, X5and X6 are C or N, and only one N exists in X4, X5 and X6; L1 and L2 are each independently selected from the group consisting of a single bond, a C1-C20 alkylene group, a C6-C30 arylene group, a C3-C30 heteroarylene group, and a C3-C20 cycloalkylene group; Ar1 and Ar2 are each independently selected from the group consisting of a C1-C20 alkyl group, a C3-C20 cycloalkyl group, a C6-C30 aryl group, a C3-C30 heteroaryl group, and Si(R1R2R3). According to the phenanthrene fused ring compound provided by the invention, compound molecules have strong planar ductility. The strong planar ductility of the compound molecules can enhance the rigidity of the material and prolong the service life of the material. Besides, the molecular parent nucleus and the aryl substituent group are prone to forming a large conjugated system, and a plurality of nitrogen atom centers exist at the same time, so that the intramolecular electron cloud density is increased, the electron mobility and the transition rate can be improved, and an organic light-emitting device has relatively high device efficiency. The invention further provides the organic light-emitting device and an electronic device.

Aryl diazinyl ketoximes: Synthesis and configurational assignment

Preparation of a series of new aryl diazinyl ketoximes (7a,b - 12a,b) required as synthetic building blocks is described. Separation of the E/Z-isomers obtained was achieved by means of chromatography, their configuration was assigned using nmr techniques. Moreover, procedures for the synthesis of the starting ketones (1b - 6b) are given.

REACTION OF METHOXY-N-HETEROAROMATICS WITH PHENYLACETONITRILE UNDER BASIC CONDITIONS

The monomethoxyl derivatives of various ?-electron deficient N-heteroaromatics reacted with phenylacetonitrile in tetrahydrofuran in the presence of sodium hydride to give α-phenyl-N-heteroareneacetonitriles in the yields ranging from 45 to 78percent.On the contrary, the reaction of these methoxyl derivatives with ethyl cyanoacetate or malononitrile under similar conditions was restricted within narrow limits.The synthesis of benzoyl-N-heteroaromatics by the air-oxidation of α-phenyl-N-hetroareneacetonitriles was described additionally.
