, p. 3669 - 3673 (2020)
A C-H functionalization strategy for the expedient access to photoreactive chemical probes of commonly found heterocyclic fragments or drug molecules of pharmaceutical relevance is described. A series of aryl glyoxylic acid reagents featuring pendant alkyne or azide clickable handles have been developed for application in the radical-mediated appendage of benzoyl fragments onto simple heteroaromatic fragments, as well as more complex drug-like compounds. This unprecedented strategy of chemical probe synthesis allows for direct access to photoreactive chemical probes without any requirement of fragment pre-functionalization or significant synthetic re-evaluation.

Paragraph 0149-0151; 0152-0155, (2020/05/01)
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.
