- Anthracene compound, preparing method of anthracene compound and organic light-emitting device
-
The invention provides an anthracene compound. The anthracene compound has a structure in the formula (I), wherein Q is the C1-60 alkyl group or the C6-60 aryl group or the C5-60 condensed ring group or the C5-60 heterocyclic group; Ar is the C6-60 aryl group or the C5-60 condensed ring group or the C5-60 heterocyclic group; and Ar1 is H, the C1-60 alkyl group, the C1-60 alkoxy group, the C1-60 ether group, the C6-60 aryl group, the C6-60 condensed ring group, the C6-60 heterocyclic group and the C6-60 arylamine group. Compared with the prior art, the anthracene compound is connected with an aromatic compound through anthracene, and the Q, Ar and Ar1 groups are introduced, so that a device emits blue light after the organic compound is applied to the organic light-emitting device; and meanwhile, the means that the above groups are used for adjusting the light-emitting wavelength is adopted, the light-emitting efficiency of the organic light-emitting device is high, and the service life is long.

- Compound containing anthracene and pyrene and preparing method and application thereof
-
The invention provides a compound containing anthracene and pyrene and a preparing method and application thereof. The compound has a structure shown in formula I, wherein R1 and R3 are independently selected from substituted or unsubstituted C1-C60 alkyl groups, substituted or unsubstituted C6-C60 aryl groups, substituted or unsubstituted C10-C60 condensed ring groups or substituted or unsubstituted C5-C60 heterocyclic groups; R2 is selected from hydrogen, substituted or unsubstituted C6-C60 aryl groups, substituted or unsubstituted C5-C60 heterocyclic groups, substituted or unsubstituted C10-C60 condensed ring groups or substituted or unsubstituted C5-C60 arylamine groups; n is 0 or 1. When current density is 20 mA/cm2, the current efficiency of the compound with the structure shown in formula I is as high as 8.9 cd/A, and service life is as long as 8500 h which is much longer than that of existing electroluminescent materials.

- Multiple C-H activations to construct biologically active molecules in a process completely free of organohalogen and organometallic components
-
(Chemical Equation Presented) Step by step: Highly selective cross dehydrogenase arylation of acetanilides was developed to construct biaryls under mild condition. With this method, different aryl C-H bonds were activated in sequential reactions to construct functionalized carbazoles (see scheme), which are present as key structural units in various biological molecules and organic optical materials.
